45-degree bevel cutter

What are they like??

Like most types and varieties of other cutters, 45-degree cutters differ in the values inherent in the three main characteristics:

Length of the product, from a few to more than a dozen centimeters. Depending on the precision of processing, the thinner, more accurate phase of the work (cutting, finishing to smoothness and sharpness of the edges and ribs of the cut product), the smaller the diameter of the cutting part is chosen.

The engine speed is 3000-15000 rpm.

What is a chamfer? Chamfer. is a surface formed by beveling the end edge of the material, it is used in technological, technical, as well as in decorative and ergonomic purposes. Chamfers on holes and welding chamfers are the most common. Of all types of chamfers most often found at an angle of 45 degrees.

How to perform this uncomplicated design element (chamfer) while spending a minimum of time and money? In this your production will help the company LLC “Rbh-tools” and our online store rbh-tools.ru. We have a wide range of quality tools and accessories for this at our warehouse on Lenkomori str. The most widespread bevels are chamfers. 2/1, pp. 1) there are high quality tools made in Japan and Taiwan at minimum prices.

The most practical solution for chamfering is the block chamfer cutter with multiple chamfer blades. Our cutter bodies are made by RBH in Taiwan, which makes them high quality and cheap. They are equipped with interchangeable multifaceted inserts made in Japan, such world brands as: Hitachi, Kyocera, Mitsubishi, Sumitomo.

Let’s go over the nomenclature of the chamfer cutters:

  • Corpus chamfer cutter CMAD. This mill under the plate Hitachi and its features are that it is able to process chamfers by milling, drilling and turning in the holes from 3 to 20 mm, it means it can be applied on the lathes, milling machines, boring machines, coordinate-boring machines. Total length of 160 mm allows you to mill chamfers in hard to reach areas, and the shank diameter of 20 mm, which makes it tough enough to work with large protrusions.
  • TC bevel cutter body. This body is good, because it gives its owner a wide choice of inserts, both from manufacturers, and from alloys and chipbreakers. This allows you to choose the optimal insert for any material to be machined. The indisputable advantage of this tool is the triangular plate, that is, the whole three cutting edges. We offer this cutter series in two versions with diameters of 25 and 40 mm, so you can chamfer the holes from 6 to 36 mm while turning or drilling, and the shank diameter in both versions is 12 mm and they can be mounted in the collet ER20.
  • VMSP router bits for chamfering. This version does not have as much choice of inserts, but has a square shape, which means four cutting edges and bodies with two teeth, which increases the minute feed, reduces machining time, and consequently reduces your fixed costs.
  • TCRM bevel cutter. This is the most interesting series in our product range. This cutter allows you to chamfer bores starting at 0 mm. But it’s also a cutter with which you can engrave any surface.

Cutter for drywall. purpose, types, review of manufacturers

Gypsum plasterboard is a very popular construction material. With its help, you can perform any work: level a wall or make an interior partition. Often with the help of gypsum board sheets are formed various arches or structures with increased complexity.

While erecting such constructions it is often necessary to minimize the number of joints between the gypsum boards. To avoid careful fitting of each such joint, its priming, reinforcing and puttying, experts are increasingly resorting. to its milling. In this article, the master plumber will tell you about the types of cutters for working with drywall.

Advantages and disadvantages of milling drywall

Plasterboard is the most suitable material for creating an original interior of any room. Drywall in its composition does not contain harmful substances and chemicals, so it is absolutely safe for health.

Plasterboard sheets differ in color and size. The thickness of this material varies: 8, 12.5, 16.5 and so on. д., and the color is gray or blue. But there are such types as GKLV (water-resistant gypsum board), GKLO (material with increased fire resistance), GKLOV (fire-resistant gypsum board).

It is not difficult to cut it, much more difficult to carry out the cutting of complex shapes of this material. Using the classic method will require a very long time, so as a tool to increase the productivity of such works, a cutter for drywall is used.

Among the undoubted positive characteristics of this method of cutting gypsum board are the following:

  • Time saving. The use of the considered technological process reduces the cost of working time in the construction of boxes and corners. Everything without exception is performed significantly quickly. In addition, there is no possibility of spoiling the material if you follow all the tips.
  • Reduced number of exposed cutters. This makes the construction tidier and also greatly simplifies the work: no need for puttying or sanding. In addition, you do not need to fix everything except the bends. this significantly reduces costs and allows you to save time.
  • The possibility of forming systems without erecting a frame. If the box or corner ledge will not be a load, you can not increase the profile of similar components. They have a good hardness of their own and will stand for many years without deforming.

The disadvantages of this method should include the following points:

  • The financial cost of purchasing a tool and cutter set;
  • Significant air pollution from gypsum dust;
  • Need to know how to select the right nozzle for the specific case.

But the ease with which milling can be accomplished allows you to completely ignore the disadvantages of this method of working with drywall.

For each specific case special cutters for working with drywall are used. The following types of drywall cutters are most commonly used:

As a rule, any highly professional technician, who often needs to use such tools for processing drywall sheets, should have such a set of cutters. At home masters, the main tool for the processing of drywall boards will be a V-shaped mill.

Application possibilities for V-shaped cutters

The installation of drywall structures, for which the V-shaped cutter is used, can be carried out independently. The capabilities of this type of cutters allow you to produce various products from drywall, the sides of which will be joined at an angle.

In this case, the edges of the GPB will be perfectly fitted to each other, which allows you to avoid additional processing of such places during the repair.

If you want to make a U-shaped box, making a depression in the material with a V-shaped cutter can easily create a shape without a frame. Such a design can be made without completely cutting the drywall. It is enough to notch the cutter in the right place of the material, and then bend and glue the cuts to get a shape that will not have joints in the corners.

The nozzle of this shape also allows you to perform a variety of shaped cuts, which are difficult to do with a straight disc cutter. The use of the nozzle allows you to reduce the time of work with the material, this quality is especially evident in the construction of large-scale interior elements from gypsum board sheets.

In order to properly mill gypsum board sheets, it is necessary to know how to handle the tool, as well as to purchase a high-quality cutter for the work.

The best result gives the V-shaped cutter on a special machine, which is not always advisable to purchase for small volumes. Often rental services are provided by construction trade centers and services, but in home conditions it is quite possible to do without hand tools.

The advantage of a handheld device is mobility, allowing you to do all the cutting directly on site. Visual inspection and adjustment of the angle of inclination is carried out with one’s own hands.

To mill drywall and create profile parts from it on the scale of the repair team or yourself will need:

  • Drywall (better if it is water-resistant).
  • Cutting table.
  • A router.
  • Cutters.
  • Industrial vacuum cleaner with cyclone filter.
  • Rule.
  • Clamps.
  • Protective equipment (gloves, respirator).
  • Painting tape.
  • Primer and brush for it.
  • Adhesive: polyurethane foam, PVA, “Uniflot”, hot melt glue, etc. д.

Work on milling and shaping parts can be divided into preparatory and basic.

  • For the convenience of further marking, cut from plywood a measure of width equal to the distance from the center of the cutter to the stop edge of the cutter.
  • On the mounting table, use clamps to secure a rule or level to use as a stop when milling.
  • Adjust the router so that the cutter makes a cut to the full thickness of the drywall sheet, but does not touch the bottom layer of cardboard. Allow for a residual layer of plaster no thicker than a quarter of a millimeter.
  • If you have many similar parts to make, it is also a good idea to cut the measurements for each joint from plywood.
  • Calculate the number of seams, the distance between them and their location on the sheet.
  • Saw off a piece of drywall of the desired size.
  • Using the edge mill, bevel the edges in advance at the points of plane joints.
  • Mark the line of the router with a scythe line.
  • Mark the edge of the router with a scythe line.
  • Place the sheet of plasterboard against the ruler.
  • Apply the measure for the cut to the rule.
  • Press the edge of the router against the measure with the left side. In free movement, the cutter moves to the left, so the stop should be on this side.
  • Make the first cut along the entire height.
  • Make a second cut through the same groove in the opposite direction. this is done for a clean cut.
  • Cut all the grooves on the side of the plate.
  • If the geometry of the part requires milling the drywall on both sides, carefully turn the sheet over and repeat the work.
  • Apply primer with a semi-dry brush.
  • Apply adhesive to the joints of one side.
  • Position the part so that the joints are vertical.
  • Apply adhesive to the joints of the second side.
  • Give the part the desired shape, check the geometry of the corners.
  • Fix the construction in this position with masking tape until it is completely dry.

Milling drywall is a very convenient and profitable solution when creating constructions from drywall. This technique, while requiring more expensive equipment, allows you to work more precisely and faster than traditional methods of working with gypsum plasterboard.

If you mill without using a vacuum cleaner, it can lead to complete contamination of the room. It is better not to perform processing on wood, because this material is denser than sheets of drywall, and therefore the edge will turn ugly and rough. For quality work is worth using high quality cutters, so take care of it in advance.

If it is financially possible, it is better to buy a complete set of cutters for the work. It makes it possible to make a specific cut and cut out shapes with different shapes. Availability of multiple nozzles also makes it possible to process materials at any degree of inclination. But it is recommended that beginners buy cheaper milling cutters, because it is worth learning to work with the milling machine first. Later, you can buy new and more expensive sets.

If you decide to buy cutters for drywall, it is worth doing it in special construction markets. There you can find all kinds of varieties and all price categories.

Among the popular manufacturers of power tools for the processing of drywall use cutters of the following brands:

  • Bosch. this type of product is in high demand, as it has great technical abilities;
  • “Enkor”. the equipment of this brand is made of strong, high-quality material, contains hard alloy tips, is distinguished by its durability and long service life;
  • “Globus”. the brand is known for producing a sturdy instrument designed for machining hard or soft wood.
  • Sekira. for the production of this brand appliances are used hard alloys, high-speed steel. this makes it strong, comfortable to work.

The choice of brand depends on the surface of the plasterboard, the size of the machine or the cost. In addition, it must fit the technical process.

Chamfering

Chamfering is often used for technical, technological purposes. is the beveling of the edge on the ends of the material. It is primarily used to reduce the risk of sharp edges. as well as for easy installation. Chamfering is carried out at different angles, the values of which are determined by the design goals. The most common angle is 45°. Mandatory chamfering is made on the ends of cylindrical shafts, bores, body parts. But it is often used in a variety of decorative elements to give them expressiveness. So on products made of wood the chamfer is made in the form of recesses on its edges. Wood chamfering can be regular, shaped and rolled (extruded). However, decorative chamfers are used to decorate gemstones, articles made of the most different materials, including metals. Chamfering makes an attractive, noble, memorable interior.

For industrial production, end mills with replaceable multi-faceted inserts with four effective cutting edges are used. They can be used not only to chamfer, but also to mill flats and ledges, shaped surfaces, conduct contouring. But what milling cutters are used for routing chamfers on workpieces at home?? Processing of chamfers, V-shaped slots, internal chamfers, chamfering for welding and deburring are carried out with small end mills, long chamfers and special chamfer mills. This operation is usually best performed at home on numerically controlled table milling machines with special programs and automatic tool change. It will not be difficult to chamfer on 4- and 5-axis mini milling machines, which have the ability to rotate not only the spindle, but also the workpiece:

  • with end mills with an angle of 90 degrees;
  • with end mills. with a planing angle of 45 degrees;
  • use long face milling cutters for chamfering.

When chamfering workpieces made of different materials the following practical recommendations should be followed.

  • Considering that in most cases the depth and width of cut is much less than the diameter of the cutter, you need to choose a high cutting speed and high feed per tooth;
  • the selected cutting mode should consider the roughness requirement for the chamfer.

Chamfering cutters ET series

For chamfering, ET series solid carbide end mills with special geometric shape, with an apex angle of 90 degrees are used. This shape can be obtained when processing the ET4SEM range of cutters on the grinding machine. Cutters with a diameter of 1-2 mm at the apex are suitable for this. These cutters can mill materials of hardness up to HRC55, including various steel grades, cast irons, heat-resistant alloys. Four cutting edges can easily be chamfered on other, softer materials: organic glass, wood, PVC, plastics, etc.д. WF-25 hard alloy is coated with black ALTiN film, making Taiwan ET cutters suitable for high-speed machining.
