is the motor that drives the electric shaft. In the future, the load is transferred to the actuators, one of them may be a drill bit for the drill. The milling cutter is a snap-in like a screwdriver or drill. Depending on the configuration and width of the cutting part in the body of the material being processed, recesses of various profiles, samples and grooves can be created.
Features of the work with a drill with an
cutter Milling involves the processing of material with a cutter installed in the fixed case of the power device. It is assumed that the instrument regulates the speed, the depth of entry into the material being processed. But the array has to move on which the action is performed. Such machines are called milling machines.
It is possible to use a drill as a milling cutter only in some cases. The reason is the particular accuracy of the work, great effort on the drive. Cutters for drills are designed specifically, taking into account the power, and methods of regulating the device. Of great importance for the work is the shape of the drill and its center of gravity.
Features of using the cutter for the drill:
- changing the load vector can damage the gearbox, if you put additional pressure on the workpiece;
- motor overheats, requires frequent rest;
- load on the plastic case can cause the armature to skew and deform;
- mount in the chuck with a horizontal axis of work is unreliable.
All this says that the drill as a frezer works in an unusual position and with uncharacteristic directions of resistance forces. To work with a milling nozzle for a drill, you need to slowly, with caution.

The tool is a shank for fastening in the cartridge and the cutter, which is made of special steel. Initially, the mill is honed under a certain operation. The equipment is made with strict accuracy to eliminate backlash. Sharpening and steel hardness is selected for the characteristics of the material being processed.
It is better to select the profile and depth of cut on a sample of material of similar hardness. In this case, the drill is installed in the clamps at the desired distance and the speed is selected that corresponds to the work to be done.
For a drill bit, only end mills with a shank are used. For long-term work without sharpening it is better to choose cutters for plywood. They can not be sharpened by yourself.
The drill bit for wood differs according to the type of treatment:
- rounding - round the corners;
- V-shaped - make a sample in the body of the workpiece;
- disk and faltsevy - create grooves;
- fillet - internal groove on the edge;
- dovetail - connecting nodes for thorn-groove;
- edging - process the edges of the planes.
Wood mills are distinguished by their mild impact on the material in order to prevent chipping and hardening of the edge to brittleness.
Features cutters with shanks for metal processing
Metal is a solid material with a uniform crystal lattice. It is processed rigidly, the main indicator is the speed of work.
Depending on the desired result, the cutter for metal of various configurations is used for a drill:
Face cones are used for vertical metal processing. More often they are treated with a plane.
If the teeth are positioned on the end and side edge of a flat disk, you can drill a recessed profile on the plane. So grooves and grooves. If you do not use a disc, a cylinder with smoothly curved grooves, you can process a horizontal surface, remove the layer, smooth out irregularities. For each operation, a special metal cutter for the drill is selected. At the same time it is necessary to remember about the load on the motor and bearings, not allowing the tool to overheat.

Requirement for the manufacture of tough cutters. The tool must work effectively, keeping the cutting surface sharp for a long time. Often, in order to save expensive hard-alloy steel, the cutters are assembled, the body is made of ordinary steel, and the teeth are made of alloys.
Cutters need to buy only from reputable manufacturers. At the same time check the quality of sharpening, uniformity of the structure, pay attention to the material of the cutting edge. Especially control the density of the prefabricated cutters.
Cutter, as any cutting tool requires careful handling. The cutting edge does not tolerate heat, vibration, and misuse.
We process plastic with a drill with an
cutter. A special feature of plastic processing is its viscosity. When exposed to a high speed cutter, the plastic first begins to be wound on the cutter, and then thinned. Therefore, the selection of drills, and processing speed of each polymer causes certain difficulties. Plastic drill for the drill is selected depending on the type of material:
From the name it is clear, thermoplastics under the action of temperature gain fluidity, chips from such materials are drain, with melted edges. Reactor plastics are not susceptible to softening when heated. Often this material is produced with reinforcement. Based on the properties of the polymer, the cutters and the processing mode are selected.
Thermosetting plastics are machined with multiple cutters, while maintaining smooth processing. The depth of one cut should not exceed 2.5 mm. Otherwise, you can get the destruction of the treated surface. Taking into account the artificiality of the material, it is necessary to organize the suction of microparticles so that dust does not get into the respiratory organs of the worker.
Soft material needs to be cut with two-way milling cutters at low speeds so that the material does not “drip”.For sheet plastic it is better to use compression mills for processing edges.
We mill concrete with
. If there is a need to process the construction with a concrete cutter for a drill, diamond crowns with external cutters are used. The milling cutter is unscrewed from the base, the shank. Pobedit layer well cleans the hole, provided a powerful drill works in hammerless mode. These crowns are used to remove ceramic tiles from the wall, for finishing cleaning.
The use of pockets for drilling is fraught with danger. The drill must be held tightly, waiting for a jerk, since the density of the material in the wall may change, and the force of the impact will create a blow.
Why do you need an
magnetic base drill When developing a magnetic base drill, you were guided by the problem of creating holes in multi-ton metal structures that cannot be moved. Farms such as a large magnet attract a pair with an opposite charge. Creating a charged bed under the drill solved the problem of fixing the tool for drilling holes with high precision.

The drilling of large cross-section holes in the metal is carried out with different nozzles, including using a milling cutter for a drill on a magnetic bed. Usually such a nozzle is used in the form of a hollow crown. Drilling a drill on a magnet on a marking is guaranteed precisely. Until the bed is energized, the drill is held on a plane with a force of several tons per square centimeter. After switching off the current, the installation is moved to a new place easily; its weight does not exceed 25 kg.
A crown cutter can drill a hole in a structure up to 130 mm in diameter.
