How to drill at right angles
Using a metal corner
The most popular and simple method for right-angle drilling is to use a metal corner. To do this, you need to put a corner in the place of drilling so that the fold is exactly in the place of the future hole. Further, the drill bit fixed in the drill or screwdriver is applied to the inner fold of the lotion along its entire length. You need to drill slowly, avoiding deviations from the corner.
Best Right Angle Dremel Tool Attachment. 575 Right Angle Attachment for Rotary Tool REVIEW
This method is very good. The holes are produced with minimal error. The only downside is that the height of the angle limits the use of the drills used. For example, for a small hole, the drills are usually short. But when using such a lotion, the tool holder will rest against it, and not allow further advancement into the depth of the material.
With an ordinary mirror
The mirror method is suitable for any drill. It should only be placed on the material to be processed with the reflective part up, and when the drill rests against it, achieve a perfectly flat mowing line between the reflection and the cutting attachment itself. If there is a deviation during work, the line at the point of convergence will bend.
The method is really very good. The only drawback is that a perfectly even angle is obtained from only one plane. This can be changed by using two mirrors.
There is a combined way to use a corner and mirrors. Mirrors are attached to the two inner walls of the corner, and the mowing line is drawn at an equal distance from the point of convergence. This method can be considered the best among the others, since the accuracy of the work done will be very high.
3 best ways to drill at right angles
Not every home craftsman has a drilling machine that will make a hole at a perfect right angle. And it is almost impossible to drill with an ordinary electric drill or screwdriver. the error will still be noticeable. And yet there are several effective methods with which you can achieve perpendicular entry of the drill into the material.
With connecting nut
An accurate drilling result can be achieved by using a union nut or several ordinary nuts coiled with electrical tape. The process of use is very simple: the lotion is placed on the surface of the material being processed and held firmly by the hand; Next, you need to insert the drill into the hole and start working.
The accuracy of the result is amazing, but there is also a drawback. Unfortunately, with such gadgets, only rarely used diameters can be drilled perpendicularly: with an M5 nut, you will have to use a 4 mm cutting attachment, and with M10. 9 mm. It will be possible to get out of the position by drilling the thread of the nuts, then the holes will be of more common diameters.
All three methods are good in their own way. It all depends on the required angle accuracy, as well as the characteristics of the diameter used. In any case, it is not necessary to purchase an expensive drilling machine for single use. It is quite possible to do with improvised means that will allow you to get an impressive result.
A completely new way to drill at right angles without specials. appliances
And by the way, all those to whom this method seems fantastic, at the end of the publication there will be a video with this, and another simple way of drilling at right angles.
Anyone who has ever tried to drill a hole exactly at a right angle (90 др) with a drill or screwdriver knows that it is impossible to do this by eye.
trying to get a right angle by eye
Of course, for this you can use cheap attachments for a drill, but more often only a screwdriver is at hand, which simply does not fit into such a device. You need to look for a drill, insert it into a special device, and all this is a waste of precious time.
And just let’s consider the option that there is no drilling machine at hand, no drilling equipment, only one screwdriver, after all, this can often be outside the walls of the workshop.
What do we need? Small regular mirror.
If you want to drill a right angle in this way, you first have to tinker a little and fill your hand, but then you can surprise your friends and acquaintances with almost a trick. By the way, in addition to a mirror, you can use a CD (are there still such in nature?), Or else, something else from which the drill will be reflected. The whole trick is that the drill and its reflection in the mirror line up in a straight line.

Making a homemade device
Devices for drilling wood: a. the use of a stop for drilling holes in round workpieces; b. the use of a stop for drilling holes in the vertical plane; c. template for drilling the end face and plane of the workpiece: 1. workpiece; 2. template; 3. holes in the template; 4. clamp with which the template is attached.
In practice, drilling a groove at a right angle can be very difficult. Often for this, many craftsmen use special devices. However, these options are often tailored to specific types of drilling equipment. Some are suitable for hand drills with accessory grip seats, while others for cordless.
There are also universal options, but they are expensive. For people engaged in the manufacture of furniture, this device is indispensable. For a person who makes something in rare cases, the cost will be quite high.
Such an assistant can be made independently, from the remnants of chipboard. The initial blank of such a device looks like bars stuffed on the basis of this material.
This is where the holes need to be drilled later to help the drill find the correct point and angle. A small part of the material is installed end-to-end on the main panel.
Before assembling the fixture, it is worth making a mark for 3 holes with different sections.
Use of the drill guide.
Take 3 screws with diameters corresponding to 5 mm, 6.3 mm and 7 mm. According to these dimensions, grooves are drilled in 3.5 mm, 4 mm and 4.5 mm.
Further, the device is assembled. Holes are drilled for the first holding component, which is immediately fixed. After that, a groove is made for another holder. At the time of drilling, a chipboard block is placed between these two parts to create more accurate results for the second element. A self-made device must be sturdy and must not walk in all directions.
Such a device will make it possible to make grooves only as a drilling device to create a right angle at the end of the panel. An additional device is made of this material to center the drill and drill a hole on a flat base. To do this, holes are drilled in a chipboard bar in an amount of 3 pieces with a diameter of 3.5 mm, 4 mm and 4.5 mm. Next, the marks on the prepared panels are fixed, the drill must go through the object, a groove is outlined.
As soon as the markings are made correctly, you need to lower the device onto the panel, place the drill, observing a right angle. Now you can drill.
The grooves are made in the same way in the end part. The drill goes through the assistant, the hole is marked, the structure is firmly connected to the side of the manufactured object, after which the drill can be used.
Using a conductor
You can drill a deep hole in a perpendicular sample using a special tool. a jig. over, such activities are carried out not only on a flat base, but also on the rounded parts of the blanks, at the corner points.
Component parts of the conductor:
- Core, allowing you to make markings for the drill.
- Plastic stencil.
- Guide sleeves in the amount of 6 pieces, the diameter of which corresponds to 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm.
How to drill 90 degrees with a drill
Anyone who has ever worked with a drill or screwdriver knows that it is very difficult to drill a hole at exactly 90 degrees by hand. This happens because we see the drill only from one side, and we can only align it in two planes. My idea is simple. using two small mirrors (they work like mirrors in a wardrobe), you can achieve an almost accurate 90 degree drilling.
All you need to make a mirror drill guide is two small mirrors, two wooden blocks and double-sided tape, or mirror glue. Regular glue cannot be used because it can damage the mirror.
You just need to glue the bars between each other at 90 degrees.
And glue mirrors to them.
Now all that remains is to attach the guides to the drilling site and simply align the drill “by eye” in parallel with your reflections. Even a slight deviation of the drill in one of the planes will be immediately visible. This is how easy it is to drill holes by hand, with almost the same precision as on a drilling machine. Another advantage of such a mirror guide is its size, with its help it is easy to drill a hole both on the wall and on the ceiling.

How to make a pvc berry picking tool.
In the process of drilling grooves, a situation often arises in which it is not easy to get flawlessly even corners. How to drill a perpendicular hole at a specific depth? To do this, you should use the advice of experienced craftsmen. They offer several options for getting out of this situation.
Hole drilling tools.
There are practically no joinery jobs that do not use a drill and fasteners. In the process of drilling, it is worth knowing about the important principles of this activity:
- you need to drill a hole only at a given point;
- the hole has a fixed size;
- at the time of drilling, the tool must be at right angles.
If all the listed requirements are clearly met, we can talk about the success in the work:
- use of special drills;
- a clear fixing of the material will help to secure the work and make it noticeably easier;
- even pressure on the drill.
So, for this purpose, you can use a wooden block of a square shape, press a drill with a drill strongly to its base and perform the desired action.
Another method is also associated with the use of a homemade device, only it has the form of the letter “T” with an internal angle of 90 degrees.
Drilling methods: incomplete holes in products in pairs (a); using an attachment plate (b); в. holes in the corner; d. in planes at an angle; d. on a cylindrical surface; e. in hollow parts.
The drill is placed at one of these points and placed on the mark, after which drilling is performed. Taking into account the length of the drilling device, the depth of the groove is determined.
To get a precise right-angle hole, you can use a guide. Its strictly fixed position will allow avoiding errors, deviations from a given angle. Certain varieties of such a tool help to make grooves not only vertically, but also while observing other angles.
The nozzle has a depth-limiting device, adjustable by a stopper and a spring. The purchase of such a tool will protect you from damage to workpieces, furniture.
Features of the position of the jig for drilling in different areas of the workpieces
Technology of drilling holes in a pipe using a jig.
- For rounded parts, use a notch without corners located on the sole of the device.
- At the corner points and on the cylinders, you should use the V-shaped element that comes with the kit.
- To fix the middle end line of the part, you need to install 2 nails in the corresponding grooves at the corner points of this device. The jig is rotated in such a way that the fasteners are connected to the edge of the element. The central part of the sleeve, intended for drilling a hole, is placed in the middle of the end part of the part.
To mark the center point of the groove, a core is taken.
- Place the named element in the middle of the hole and fix the stencil on it.
- Put the bushing on this post with the expanding part upwards, its diameter corresponds to 4 mm, insert into the template. Such a part must be centered and pressed against the material with a clamp.
- Remove the core together with the bushing from the template, which should not move.
- The guide sleeve is placed in the stencil of a certain section.
- Using a drill, a hole is made of a certain depth.
Practical advice from specialists
Concrete wall drilling pattern.
In order for the drill to stand exclusively vertically in the process of drilling the openings, use a square. It is placed strictly at right angles, in parallel with the drill.
Regular carpentry work involves the purchase of a special stand, it will hold the power tool perpendicularly. The stand allows you to control the depth of the grooves.
To firmly fix the wooden block, you should use a vise or workbench. Holding the material in your hand is completely unsafe: at the time of its processing, a dry base can crack and crack, injuring the master.
To ensure the smoothness of the entry slot, it is recommended to place any remnant of the board under its base, which can later be thrown away. You can drill the product. This technique works well for flat surfaces.
Drilling a hole straight at a 90 degree angle is not an easy task. It can take a lot of effort to keep the drill straight and vertical. BullseyeBore suggests doing this with multiple laser concentric rings.
The BullseyeBore drill uses a simple red laser to project three rings onto the surface where you are going to drill. To keep the drill as level as possible during the process, observe the three rings. The two inner ones will remain in the same position, no matter how the drill tilts, and the outer one can move. By aligning the position of the largest ring with the two smaller ones, you will provide the drill with a strictly vertical position, and the hole will turn out to be just perfect.
In addition, concentric rings can provide information on the depth of the hole. The distance between the large and middle circles will just indicate the drilling depth. If at the beginning there is such a picture:
In the middle of the process, the circles will get closer together:
And in the end they just merge:
The bit looks like a small transparent disc with a connector for easy installation on any drill. Lasers, optics and batteries are already installed inside. The disc is smooth, lightweight and shockproof.
Manufacturers are now developing a model where all the filling will be implanted into the drill chuck.
Right angle drill attachment
Greetings to all lovers of tinkering, today we will look at how to make a drill guide that will allow you to drill holes at right angles. The homemade product is made of plywood, and the author made the guides from steel tubes so that the weight of the attachment is not too large. Thanks to such a device, it will also be possible to confidently drill holes of large diameters using crowns. If you are interested in the project, I suggest studying it in more detail.!
Materials and tools used by the author:
List of materials:
– steel rods;
– threaded rods and nuts;
– joiner’s glue;
– self-tapping screws;
– epoxy adhesive;
– two springs.
The process of making homemade products:
Step one. We cut the details
First of all, we will cut all the necessary parts. If you look at the device, you can see 3 parts that are the same in shape, they have the shape of a horseshoe. We cut out these three parts so that they turn out to be the same, they can be glued together with double-sided tape and sanded all together.
After that, we immediately outline the places for the holes and drill them at right angles on a drilling machine. These holes will be needed so that you can install the tubes that are guides.
In the end, do not forget to cut out the base, you can glue one of the “horseshoes” made earlier to it with wood glue.
Step two. Central block
We make a central block that will move on the guides. A drill will be clamped in the central block, it is for it that we must make a clamp. We drill a hole with a crown in the diameter of the front of the drill, to which the handle is attached. Depending on the shape of the drill body, we modify the clamp with files.
The clamp will be pulled together using threaded rods and nuts, we wrap the threaded rods in plywood with epoxy glue. So that the clamp can be unscrewed and the drill can be taken out, the author uses “wing nuts”.
In the end, you will need to make and install linear bearings in the movable unit, these are a kind of bushings. Such bushings can be made on a lathe, each bushing is made of round timber through which holes are drilled. You can also use off-the-shelf steel linear bearings sold in China. We glue the linear bearings with good glue and fix them with self-tapping screws.
At the end of the step, as an additional support for the drill, the author glued and screwed on a triangular piece of plywood with self-tapping screws.
Step three. Assembly
We assemble the structure, first we install steel pipes in the base, the pipes are fastened with self-tapping screws or screws through the holes in the base. Next, you can install the middle mobile platform, after which we attach the upper platform. We securely fasten the tubes at the bottom and top with glue and screws so that nothing is distorted.
After making sure that the central block moves easily and does not wedge, you can install the springs. At first, the author put one spring in the center, but it was not enough, in the end it was decided to put two springs on the sides, which began to raise the platform with even and great effort. We fasten the springs with self-tapping screws and washers.
Step four. Final touches and tests
The homemade product is almost ready; at the end, a large diameter hole must be drilled at the base. We install a drill in the clamp and, using a large-diameter crown, drill the base.
We also fasten a wooden handle to the base, for which you can firmly hold the machine. And so that the drill does not fall down, the author made a retainer from wire.
First, you need to perform certain manipulations with the drilling tool. To do this, twist the nut and the fixing drill from the drill. After that, you need to mark its diameter on the plastic bottle as close as possible to the neck. Then transfer the circle corresponding to this diameter using a felt-tip pen. You should end up with a full circle.
This template, which must be cut out later, should also be noted on the bottle cap, and care should be taken to ensure that its width is sufficient for this.
The next step is to trim the bottle or jar. The choice of the trimmed structure should be approached very carefully, since this will further affect the depth of the holes created with the help of the guide.
Special attention should be paid to work safety. To do this, it is recommended to sand the edges of the can to make them even and smooth.
The holes that were previously applied to the bottle and its cap should be cut exactly along the intended mowing line using a clerical knife. Processing should be carried out with the edges of the slices, which must be thoroughly sanded. Then they take the lid and place it with the front side in the jar, acting on it with physical force to ensure the most snug fit. It is in this area that it is glued.
The strongest possible connection can be achieved if, after applying the glue, a strong compression is ensured, which must be maintained until the adhesive dries. Given that doing this work manually is fraught with certain difficulties, it will be useful to fasten several thin elastic bands on top, thanks to which the required pressure can be maintained.
After waiting for the glue to dry, the drill attachment can be used for its intended purpose. A drill is pushed into it, after which, using a plastic nut, it is fixed on the tool and the hole is drilled. Although it does not provide a choice of depth, this problem can be solved by making several of these tips and using the most suitable one as needed.
Semi-professional drill guides
Semi-professional guides can be equipped with various fixing devices for the bed, drilling depth adjusters, the angle can be set both along and across the tool swing plane. This makes the equipment more bulky.
Drilling work is one of the most frequently performed during the manufacture of various structures. over, a home craftsman most often solves this problem with a household drill. However, for the most part, the hole created does not differ in exact dimensions. And this can create certain difficulties when using it for its intended purpose.
You can get out of this difficult situation with the help of drill guides, which you can make yourself. This idea seems quite attractive for the reason that any owner can make such a nozzle, given that any available means can be used for this. However, having realized all the attractiveness of the guide, it must be remembered that it will not be able to become a full-fledged device for a drilling tool, so you should resort to using this nozzle only in emergency situations. Otherwise, the drill guide will fail pretty soon.
For the manufacture of the guide, the following materials and tools must be prepared:
- plastic bottle;
- plastic cover;
- stationery knife;
- felt-tip pen;
- universal glue;
- circular drill;
Making guides for a household drill with your own hands
A drill is usually used to create holes in the wall. But at the same time, there is no guarantee that it will turn out smooth. Therefore, to eliminate this drawback, you have to use additional devices in the form of a drill guide. Using it, you can do this work with less physical effort. At the same time, difficulties arise when drilling a hole at an angle of 90 degrees, and during the performance of certain works, the angle of the hole created should often be 45 degrees. In this case, it is necessary to carry out appropriate preparation of the working tool in order to fulfill this requirement.
It is quite difficult to create a hole in structures made of materials that are too hard. This causes the drill to slip out during operation, posing a hazard to the worker and those around him who could be injured. You can avoid such unpleasant consequences and at the same time simplify such a process with the help of such a device as drill guides. If necessary, they can be made independently, and the presence of a large number of options allows you to choose the most preferable among them.
Professional drill guides
As a rule, professional rack guides are equipped with their own drill chuck. Why is it done?
Even the most accurate drill clamp has a serious error. In addition, the drill gradually wears out, the bearings on the shaft give a little backlash. All this affects the drilling accuracy.
The fastening of the standard guide chuck is less susceptible to wear, since it is used less often. Plus, it doesn’t matter to you which drill connects to the chuck. It’s just source of rotation.
- high accuracy;
- thoughtful fastening to the workpiece;
- the ability to perform work with high intensity and load.
- high price;
- narrow specialization.
The device is a plastic case, in which guide sleeves for different diameters of drills are rigidly fixed. By limiting the deviation, you can drill with acceptable accuracy, and on various materials.
The jig is held with one hand and the other holds the drill. It is not necessary to constantly monitor the slip angle. In addition, the fixture allows you to accurately start drilling at a given point. No punching required.
Almost all guides with an angle of 90 ° allow you to work on rounded surfaces (pipes). For this, a special groove is provided on the lower support heel.
There are also simpler designs (if a clip for several diameters is inconvenient to use). For example, a mandrel into which bushings of various sizes can be inserted.
In addition to standard guides with an angle of “attack” 90 °, there are specialized conductors in which the bushings are located at a different inclination.
- low accuracy (there is a slight backlash in the guide sleeve);
- wear effect on the drill.
