How to spin an angle grinder if it is jammed

Table of Contents:

With a gas wrench

This method is considered not entirely safe, since the stopper can be broken, although in most cases, it is possible to unscrew the nut. To avoid breaking the spindle lock, do not apply too much force to the gas wrench. Retainer is designed to withstand the force of a standard wrench.

An overly tightened flange can be unscrewed using 2 gas wrenches. To do this, break off the protruding ends of the abrasive wheel with pliers so that you can reach the bottom flange with the first gas wrench. Next, tighten both flanges with wrenches and turn them in opposite directions (taking into account which thread on the spindle is right or left).

Purpose of discs and attachments

Discs for an angle grinder differ in purpose for:

  • detachable;
  • stripping
  • grinding;
  • sharpening.

Using a puncher

Some owners of an angle grinder, in a situation where the clamping nut is jammed, install a “chisel” or “jackhammer” nozzle into the hammer drill, insert it into the hole of the flange at an angle and turn on the hammer mode without rotation. Accordingly, the stop button must be pressed. Just a couple of gentle clicks with a perforator are enough (so as not to break the shaft retainer), and the nut will begin to turn.

How to properly change a disc to an angle grinder

Since wheels for an angle grinder are consumable, sooner or later they have to be changed. They are attached to the spindle of the angle grinder using a clamping flange (nut) with an M14 thread. To unscrew it, a special open-end wrench with pins on one side must be included with the angle grinder.

So, to replace your tool with an angle grinder, follow these steps.

  • De-energize the device by unplugging the power plug.
  • Lock the spindle of the angle grinder using the button located on the front of the housing. When the button is pressed, the stopper enters the hole of the disk installed in the gearbox, which fixes the spindle in a stationary position.
  • Insert the pins of the key into the holes on the pressure flange.
  • While holding the latch with one hand, turn the wrench to the left (counterclockwise) with the other hand until the nut comes loose. Then it can be unscrewed without a key and removed from the shaft. In this case, the spindle of the angle grinder rotates clockwise. But in which direction to unscrew the nut if your apparatus rotates the shaft counterclockwise? Remember: the clamping flange should always be unscrewed in the direction opposite to the rotation of the shaft.
  • Now you can change the tool after removing the old one. If you notice that dirt has accumulated inside the casing, then remove the bottom flange and use a steel brush to remove dirt from all surfaces.
  • Screw the flange onto the shaft by hand. Tighten the nut until you can no longer turn it without a key. After that, holding the stopper, tighten this nut with a wrench, but no more than a quarter of a turn, otherwise the disc will begin to deform.
  • After performing the above steps, the tool change is considered complete.

    Choosing and Replacing Discs for Angle Grinder

    Angle grinder (angle grinder), in common people called “angle grinder”, is widely used in construction and in everyday life during repairs. It can be used to carry out many different technological processes. In order to choose the right tool for performing a certain type of work, you need to familiarize yourself with what kind of discs and attachments for an angle grinder are. The tool for this device is selected by size and purpose.

    Sharpening

    To sharpen the tool, grinding machines (sharpeners) are usually used. But if you do not have the latter, but you have an angle grinder, then you can purchase a sharpening (grinding) wheel for it, with which you can easily sharpen almost any cutting tool.

    The main difference between sharpening wheels and cut-off wheels is their thickness (at least 5 mm).

    Using a penetrating lubricant

    Liberally spray the flange-to-shaft connection with WD-40 fluid. It tends to penetrate into inter-threaded spaces and small cracks. After applying the liquid, wait about 5 minutes and try to unscrew the fasteners with a standard wrench.

    Disassembly of the gearbox

    In the event that the retainer is broken, you will have to disassemble the gearbox to remove the tool from the angle grinder. Use pliers to break off the edges of the remaining abrasive wheel so that you can get to the bolts holding the gear cover. After that, unscrew the fasteners and open the gearbox. The cover will be removed together with the pinion shaft. Further, this shaft should be clamped in a vice, having previously laid aluminum gaskets between the steel jaws, and using a gas wrench, unscrew the flange (do not forget to determine the direction of unscrewing).

    Why is the lock nut tightening?

    The angle grinder, depending on the brand and diameter of the working disk, develops from 6,000 to 12,000 revolutions per minute. When the rotating disk sharply touches the surface to be treated, the following rapid processes occur.

    The cutting disc, cutting into the material, experiences great resistance and slows down somewhat, but the rotor of the electric motor rotates for a few more moments by inertia at the same speed and literally twists the spindle thread into the lock nut, pressing it into the cutting wheel. Now it will not be easy to unscrew it, especially with a native key.

    There are various ways to get rid of this defect. Not all of them pass without leaving a trace for the instrument. Here we will consider one of them, which can be called auto thermal.

    How to unscrew the disc nut of an angle grinder (angle grinder) if it is bitten

    So, if there is no way with the key, even if you insert it and hit it slightly with a hammer, then we begin to use something more serious.

    The first thing to try, but again without fanaticism, is to take a rod, insert it into the holes on the nut and, using a hammer, move the nut in the direction of its untwisting. The main thing here is not to break the button and not to rip the holes, as here

    The second thing that many advise is to warm the nut. We warm up the nut. As a result, it is slightly, but physically still obliged to expand. Resizing may or may not help.

    Do not pull all the way until the scroll hold button stopper or the button itself bursts. In this case, it is not the tool with which you unscrew it that breaks, but often the case of the angle grinder.

    The third method is the most effective, and, oddly enough, one of the safest for the angle grinder itself.
    We take and break off the edges of the disk along the nut.

    Next, we use a thin metal plate or another disc (thinner), and maybe a second angle grinder with a disc. In this case, a broken disc must be turned either with a plate or a disc. We try to sharpen the disc so as not to damage the nuts holding this disc, because they will still be useful to us. So we sharpen the whole broken circle until we grind it off and the nut is unscrewed.

    This business is 4-5 minutes, no more.

    If you will be using a second disc or metal plate, it is best to insert them in a vise to hold them. Since it is dangerous to hold such objects with your hands. This method is the most effective.!

    With a gas wrench

    The shoulder when using the gas wrench increases, therefore, the moment of force also increases. It is easier to unscrew stuck joints with such a tool. But if you try too hard, you risk crushing the flange or breaking the spindle rotation lock.

    How to unscrew a disc (nut) on an angle grinder, if bitten, jammed, does not unscrew

    an angle grinder, or as it is called more popularly and in a popular way, an angle grinder, nowadays an irreplaceable and very useful tool. Without him, neither here nor there! And if it suddenly fails, then you have to dodge in every possible way, look for alternatives and think about restoring the instrument. At the same time, it is impossible to use an angle grinder for its intended purpose because of what seems to be a simple lining when the disc cannot be unscrewed. Rather, the nut that holds this disc is not unscrewed. Here you can “break the wood”, namely, bend or break the key, damage the lock button, break the case, but never unscrew that same unfortunate nut. So, we will warn you right away, if it is not too late. If you suddenly do not unscrew the nut holding the disc with a key, then you need to change your tactics. And it is precisely the cardinal method of unscrewing that our article will be devoted.

    How easy it is to unscrew the nut of an angle grinder if the disc is jammed

    With a hammer drill in jackhammer mode

    The hammer drill must be switched to the chiseling mode without rotation. A 6 mm drill must be placed on the end of the flange or rest against the edge of the hole. The task is to unscrew the nut, to move it from its place. After that, unscrew it with your hands or with a key. During work, you need to block the rotation of the spindle.

    How easy it is to unscrew the nut of an angle grinder if the disc is jammed

    Various mechanisms make our work easier, both in production and in domestic conditions. But sometimes they bring unexpected and not very pleasant “surprises”. After all, it is impossible to foresee all the situations in which you will have to use the tools.

    This also applies to an angle grinder (an angle grinder. an angle grinder), when the cutting disc is clamped on it so strongly that it is impossible to unscrew the clamping nut with a standard wrench or other tools or methods. In this case, there is a risk of breakage of the quick clamping button of the disk and even the body of the tool, usually made of aluminum alloy. The matter is further complicated by the fact that the surface against which the working disk is pressed is often round and it is impossible to stop it.

    How to avoid biting the disc nut on an angle grinder

    And a few words about preventing such unpleasant precedents again. You can use small cardboard spacers by inserting them between the disc and the nut. As a last resort, we use a disc of a smaller diameter, unless of course the nut is tightened from above. As a result, it will be possible to unscrew such a nut without any problems. It will not be squeezed, for a bite on the thread.

    And another small video about a problem that I studied on my own experience.

    How to unscrew the nut on an angle grinder without a key: a simple life hack

    Before you unscrew the nut on the angle grinder, you will have to completely crumble the disc. If it is already destroyed, you can break it with your hands. There is an option to cut whole circles with a hacksaw on another blade for metal. The inner iron ring and pieces that do not lend themselves to mechanical stress must remain from the abrasive wheel. Then it is necessary to clamp an iron profile or any unnecessary plate in a vice, the thickness is less occupied in another way equal to the thickness of the disk (but no more). Then turn on the angle grinder and grind off the remaining abrasive to the seat sleeve. Subsequently, the flange can be simply unscrewed with the universal angle grinder wrench.

    The clamping nut must be heated with a hot air gun, in other words, with a gas burner, so that the metal becomes more pliable. Then turn it out with a universal wrench or with your hands. But the risk of this method is that you can spoil plastic parts and gearbox elements.

    With a gas wrench

    The shoulder with the use of the gas wrench increases, as it follows, and the moment of force also increases. It is easier to unwind stuck joints with such an inventory. If you try very hard, you risk crushing the flange or breaking the spindle rotation lock.

    switch to chiseling mode without rotation. A 6 mm drill must be placed on the end of the flange or rest against the edge of the hole. The task is to unscrew the nut, to move it from its place. Then we unscrew it with our hands, in other words, with a key. In due time of work, it is necessary to block the rotation of the spindle.

    Tapping the nut

    This method is similar to the previous one, with the difference that instead of a hammer drill or hammer drill, a chisel or metal rod of a suitable diameter is used. Having locked the spindle of the angle grinder, you need to insert the rod into the hole in the nut and tap it with a hammer in the direction of the wheel’s movement. By moving the flange slightly from its place, it can be unscrewed by hand. This method has the same disadvantage as when using a punch.

    How to unscrew the nut on an angle grinder without a key: a simple life hack

    An angle grinder or angle grinder is one of the most traumatic power tools. If used improperly, the cutting disc can jam, and even if everything is okay, after this incident, it is unlikely that it will be possible to unscrew the fixing nut after this incident by standard methods. neither a “native” key, nor a gas key, nor even a chisel with a hammer will help. How to unscrew the nut on the angle grinder?

    Measures to prevent jamming

    By taking care of the safe operation of the angle grinder in advance, you will save yourself the trouble of taking corrective measures. Such events include:

    • Placement of cardboard or plastic washers between disc, flange and spindle head. They do not allow the tool to jam, but even in the case of a corkscrew, they can be removed / melted and the element can be easily unscrewed.
    • The abrasive wheel must be correctly positioned. To do this, place the front side of the circle on the support flange (picture to the gearbox). It must not come into contact with the clamping nut. In this case, the standard metal ring in the center will act as a washer that protects against jamming.
    • Weld a regular nut on the clamping flange, which allows you to press the installed disc using a conventional wrench.
    • Check the tightening torque. No excessive force is required to install the cutting element. Otherwise, it will jam under intense loads.

    Conclusion: Difficulty replacing the grinding wheel

    Before removing the grinding wheel, it is better to try to unwind all parts and remove unnecessary objects that may be an obstacle. This makes it easier to change the grinding wheel.

    How often you need to change your angle grinder wheel depends on how often you use your angle grinder. If you use it often, your wheel will wear out faster and you will have to change the grinding wheel more often.

    Try to avoid malfunctions and change the grinding wheel in time. To protect yourself and not endanger your health, make sure that the power supply is not connected to your grinder before any manipulations.

    Difficulties in wheel replacement arise when nuts, washers, and screws become jammed or rusty. In this case, you will have to try several ways to remove the circle and make a lot of effort. It is also important to consider that grinding wheels can be very fragile. If you do not want breakage and deformation, you must be extremely careful when applying force to remove them. Remember that specific grinding wheels are suitable for specific metals. Choosing the wrong sanding disc is one of the causes of breakdowns and malfunctions.

    Why bites the nut on the angle grinder that holds the disc

    I will say, perhaps, a well-known truth. It bites nuts more often on angle grinders with a disc size of a significant size, say 150-180 mm or more. The thing is that the resulting torque, in the case of a disk impact at the time of the beginning of cutting, is much greater than for a disk, say 125 mm. As a result, by inertia, the nut tightens so tightly that it is very difficult to break it in the usual and usual ways. Now about the special ways.

    How to change a disk if it is jammed?

    What to do if the wheel on the “angle grinder” is stuck? This can happen, for example, when, as a result of work, pieces of the workpiece being cut sharply clamp the rotating disc. This often leads to its destruction.

    To unscrew the nut tightened as a result of rotation, if the circle is bitten, it can be very difficult.

    • One of these methods would be to use two gas keys at once. In this case, the remains of the disc must be broken with pliers. With one key, you need to clamp the part of the stem located under the disc, and with the other, unscrew the flange.
    • Sometimes, to gain access to the gas wrench to the rod “angle grinder”, you have to disassemble the gearbox.
    • A simple device saves from the problem of a jammed nut. cardboard or tin washers. They are often sold with an “angle grinder”. But over time, they can be lost or become completely unusable. Making homemade washers is not at all difficult. However, it is better not to neglect them.

    In extreme cases, the flange can be sawn with a hacksaw for metal and then replaced with a new one.

    How to remove it?

    Discs, especially those designed for cutting, burn out quickly and have to be replaced.

    It will be useful to remind once again about the need to disconnect the “angle grinder” from the network. Work to be done with fast rotating parts and better protect yourself.

    If you need to replace a worn disk, you need to perform a number of simple operations.

    spin, angle, grinder, jammed
    • The disc is secured to the stem stem with a threaded nut. In the kit of any angle grinder there is a special key, on the arms of which pins are fixed, which cling to the holes of the flange.
    • The spindle is fixed with a special button, the cotter pin of which, when pressed, enters the hole of the gearbox, thus fixing it. Having pressed the button with your right hand, at the same time with your left hand you need to unscrew the fastening nut with a wrench. If the nut has moved from its place, unscrew it by hand. That’s it, now the disc can be removed.

    Fix Locked Up (Jammed) Angle Grinder With Minimal Tools

    • There are times when the key, for some reason, was not at hand. What to do? The easiest way out is to stop working. But, as they say, this is not our method. It is also possible to unscrew the clamping nut of the “angle grinder” without a key. Often a pipe (gas) wrench is used for this. On such a key there is a device that spreads it. It is necessary to tighten the nut and, fixing the “angle grinder” gearbox with a button, move it from its place. Then it can be unscrewed by hand.
    • The nut has holes for fixing it with pins on the key horns, you can unscrew it by tapping with a hammer on a chisel or a bar that is pressed into the hole.
    • It is sometimes possible to push the nut off by simply tapping its edge with a hammer in the direction of twisting. However, in this case, damage to the flange may occur, especially the holes for the pins of the key; in the future, it may be impossible to apply the key to such a nut.
    • A very good result is obtained when using a nail to make a key. It is better to choose a large nail, from 100 mm. Using a hammer and pliers, the nail is U-shaped. With a hacksaw or chisel, the point and head of the nail are cut off. With such an improvised wrench, you can try to knock off the nut. You can bend the ends of such a key, then it will turn into a kind of open-end key, but this will require a lot of labor. You can also insert a gate, for example, a hammer or other nail, into the arc formed by a bent nail.

    How to Place a Disc on an Angle Grinder Correctly?

    The disc “angle grinder” (angle grinder) is one of its main working parts. It is the disc that determines the use of the instrument. With it, this machine can be used to cut, grind or polish various materials. Discs, depending on the purpose, differ from each other: from abrasive grit. for metal, steel milling cutters and circular saws. for wood processing, with diamond dusting. for stone and tiles, all kinds of brushes, brushes and emery wheels. for polishing various surfaces.

    The disc “angle grinder” is a consumable material, you cannot save on it in the process of work. The disc will gradually wear out (burn out) and must be replaced. When planning work, you need to be prepared for this and it is better to stock up on several removable disks in advance.

    How to install correctly?

    Installing a disk on an UMSH is not so difficult. You can change it simply by following the instructions, although there are some nuances here.

    First of all, you need to install the disc in the correct direction. This is especially important if it is detachable. Usually the side of the disc with the label on which the marking is indicated and, accordingly, the scope of its application, is slightly different from the opposite side. It may not appear immediately, but with prolonged intensive work, the difference will not only be noticeable. it will be obvious.

    On the side on which the label is glued, a wide pressure washer is placed, and the movable nut acts on it when tightening (installing the disc). The nut slides on the polished surface of the washer, without it it will become more difficult to tighten or unscrew, since the abrasive will firmly hold the nut and more effort will be required. This is especially important if a quick disc replacement is required or if it breaks down (jamming).

    There is always a chance of disc failure, but when installed correctly, it breaks only under heavy loads, the structure of the discs takes into account the difference in loads on both sides.

    With circular saws or other products that have teeth or a significant difference in two sides, there is usually no problem how to set. For example, a grinding disc cannot be fixed on the contrary: it will simply be impossible for them to work.

    Discs for stone, including diamond ones, have a special rotation indicator in the form of an arrow: when installing them, you need to fasten them taking into account where the rod will rotate.

    It is also important to consider the size of the disk when installing. In no case should you neglect safety and remove the protective cover. it is better to choose a disc of the appropriate diameter. Sometimes a worn-out disc from a large unit is placed on a smaller “angle grinder”. However, a worn disc, as a rule, cuts worse, the working surface is limited to about half the radius of the disc, the structure is slightly different. The disc burns faster and does less work. This operation can be justified if the diameter of the stem is the same. But you won’t be able to change it back.

    Debris must not get under the disk when installing. Of course, the clamping nut may well squeeze small objects, something will press into the surface of the circle. But an imperceptible skew will cause a displacement of the plane of rotation and, as a result, a strong vibration of the entire mechanism, it can cause the destruction of the disk and, of course, you should not hope for an accurate cut in this case.

    Before installing the disc, the “angle grinder” must be disconnected from the mains. this is a basic safety requirement, since a sudden turn on at this time is fraught with serious injuries.

    The clamping nut must be unscrewed with the wrench supplied with the tool. To prevent the stem from spinning, it must be locked by pressing a special button. It is necessary to unscrew the nut while holding the button down.

    After twisting the nut, the disc is put on the released stem, with the front side out, and you need to make sure that it is installed exactly in the seat.

    Angle Grinders. 5 Common Issues & How to Fix Them

    spin, angle, grinder, jammed

    The kit for the new “angle grinder” always includes a certain amount of cardboard spacers. when installing the disc, they must be laid so that they are between the disc and the clamping elements. These pads will help unscrew a broken or jammed disc.

    Further, the nut is manually tightened to the stop and tightened with a special wrench. That’s it, the “angle grinder” is ready to work.

    Advice

    If you had to use a gas wrench, you must remember about the very powerful shoulder of such a wrench and about the effort that is applied to the “angle grinder” parts. If you do not act carefully, the spindle lock could be ripped off or the gearbox could be damaged.

    All manipulations with the disc of the angle grinder must be carried out with the power supply completely disconnected (the plug must be removed from the socket). Any inadvertent pressing of the start button will cause the electric motor to turn on, and the rod rotation speed is very high. In this case, injuries cannot be avoided.

    Working with an “angle grinder” involves a lot of waste in the form of metal or wood shavings and dust. Before starting work, you must wear special safety glasses: they will protect your eyes from fragments of the cutting wheel itself in case of jamming and destruction.

    Glasses are needed not only as a safety element. If the eyes are protected, more attention can be paid directly to the work of the “angle grinder”, to ensure the correct cut or the choice of the correct mode of operation. This will allow the most efficient use of consumables (cutting wheels), minimize the occurrence of abnormal situations with a biting disc or its destruction.

    A protective mask that completely covers the face will perfectly replace glasses. this is especially important for a visually impaired master who wears diopter glasses, on which safety glasses cannot be worn.

    The disc on the “angle grinder” can be installed both “away from you” and “towards you”, depending on the direction of rotation and, accordingly, the flow of chips. This does not make a fundamental difference in work. However, the “angle grinder” with a circle “towards itself” when biting the disc tends to jump out of the cut forward, and not on the one who uses it. This is especially important when working with powerful tools, but even a small angle grinder can pose a serious hazard.

    A specially mounted extension cord with a plug socket, preferably without grounding, will help to quickly stop the operation of a machine that has escaped from the hands.

    “Angle grinder” is a rough tool and it is not worth striving to obtain an ideal surface as a result of its work, the main thing is to make a rough cut, which later, if necessary, can be processed in other ways.

    To work without clamps and jamming, it is better not to cut long metal workpieces to the end, leaving 1–2 mm of metal in the cut: they will be easy to break off afterwards, this will practically not affect the quality of the workpiece.

    It is better to place small workpieces in a vice or press them with a clamp to a workbench or other reliable horizontal surface. The quality of the cut and safety depend on the density of pressing.

    You can watch the following video on how to put the disc on the “angle grinder” correctly.

    Which side to put the disc on the angle grinder, what to do if the disc is jammed?

    Most specialists in repair and construction work today are familiar with the angle grinder or, as it is popularly called, the angle grinder. It is used to process a variety of materials, including stone, reinforced concrete, concrete, marble and many others. At first, beginners may have a number of questions, among which the most frequent are: how to properly install the disc on the angle grinder, how to attach the disc to the angle grinder, which side to put the disc on the angle grinder, and in which direction the disc should turn on the angle grinder. Let’s try now to give short answers to all these questions.

    spin, angle, grinder, jammed

    What you need to install the disc?

    Attaching a disc to an angle grinder is usually a fairly straightforward process, with a few rules to follow. In order to produce it, you need to arm yourself with the appropriate tool. a wrench, which will be needed to unscrew the nut. The next step after it has been unscrewed will be the replacement of the angle grinder disc or its initial installation. If something happens that grips the disc in an angle grinder, to remove it, you will have to crumble it and remove the remnants from the gap between the support flange and the nut using a flat screwdriver or chisel.

    Which side to put the disc on the angle grinder?

    Which side to put the cutting disc on can depend on several factors. Firstly, if the disk is not flat, then there is only one way to install it, and the question disappears by itself. Secondly, if the circle is still flat, you can focus on the label. if the angle grinder rotates away from itself, then it is installed with the label inward, if on itself, then, respectively, outward. If this principle is not followed, then you can expect undesirable results. a breakage of the disc during the sawing process or simply its quick wear.

    spin, angle, grinder, jammed

    As for the direction in which the disc rotates on the angle grinder, this is primarily a safety issue. It is believed that it is necessary to cut concrete in the direction of rotation of the disc or towards yourself. In an ideal position, the sparks should fly to the side to the left of the person operating the tool. If this does not work, then you can use a different position, when the beam of sparks is directed downward. In any case, a situation should not be allowed when sparks fly from the user, since in the event of a sharp jamming of the disc, the angle grinder will be directed in his direction.

    In other words, cutting materials against the direction of rotation of the disc or away from yourself is extremely unsafe, since in the case of a wedge, there is a sharp throw of the angle grinder in the direction of the person who is working. By the way, if you have additional questions about how to install a disc on an angle grinder, you can also watch training videos, which are more than enough on the Internet today.
