The modern tool market offers it in a wide range, even ring cutters are represented by dozens of models. Each of them has its own characteristics. In order for the ring mill to be able to fulfill all the expectations assigned to it, it is necessary to choose it correctly. Let’s see how to do it best..
Determined with the shank of the ring mill
A number of manufacturers of drilling machines use unique shanks in their manufacture, as a result, the buyer is forced to use exclusively their branded products. Such manufacturers include Nitto, Fein, and others. Other companies produce equipment with standard shanks..
It is important to understand that ring mills with unique shanks have a higher cost, and the difference in price is quite noticeable. Their use leads to higher prices for finished products. In addition, such a tool is less common, so if you have to buy a mill with a unique shank, it may not be in the whole city. So, you have to order online and wait for their delivery.
If the machine has a unique shank, you can purchase an adapter that allows the use of universal products.
We choose the material for the manufacture of ring mills for metal
Particularly widespread today are quickly cutting steel and hard alloys. The material of the first type in the common people is called «quick cutter», For this, special HSS steel is used, thanks to which it is possible to produce holes at higher speeds. An important advantage of the material is resistance to fracture. Hard alloys are special plates that are soldered into the cutter crown, they serve to cut metal.
Each material has its own characteristics, consider them in more detail:
• cost – carbide cutters are more expensive than quick cutters by approximately 20-25%;
• sharpening – carbide milling cutters do not require subsequent sharpening, but quick-cutters lend themselves to such processing;
• durability – the service life of quick-cutting tools is usually 20-25% lower than that of carbide tools;

• staff qualifications – carbide milling cutters require higher qualifications of specialists, otherwise a tooth can be quickly knocked out of the tool crown. It is impossible to restore such a defect; you will have to purchase a new cutter.
Having become acquainted with the features of various types of ring mills, you can choose the most suitable.
