We have a choice of mills with universal connection made of HSS, Cobalt-8 and since recent time from Tungsten Carbide Tipped. For each car we have also a tool, necessary to its use.
Ring mills (koronchaty drills) are 5 mm longer than Euroboor, in difference from mills of other producers, what is 20 more favorable
Ring mills (koronchaty drills) are intended for performance of through openings by diameter to the 12-130th and up to 100 mm in depth. Thanks to a special design use of the powerful drive as forces of cutting are small is not required. Operation happens at much more favorable modes of cutting. In the course of drilling only metal on an opening contour is removed. Ring mills are made fast-cutting and hard-alloy.
The surface received on an opening circle has considerably the best indicators of a sinuosity and a roughness, than when drilling by cylindrical drills. Koronchaty drills provide unprecedented productivity at small consumption of power, advantage in comparison with spiral drills increases with increase in diameter of drilling.
