Description

The invention relates to metalworking devices, namely, hollow drills for hole drilling, and is non-harmful:) - starting to be used for ring drilling: 1 (glass holes) in parts.

The aim of the invention is ionization with performance.

At the end of Cornus 1 in the Nazi 3 set a pair of incisors -1 and 5,: 1 the equal cutting edges are executed in the form of a broken line; 1 of two sections, Here, cutter 4 and section b of cutter 5 of the paklsluNy under the 6O.1YN angle to the plane BUT: 1 is the longitudinal longitudinal axis 6 of the head than the area from 1cc 4 and the section c1 of the ride 5, they drink in the radial N) avlepii o-jusi- 1 the inner side of the outer H: i:; i4 p is the names of Cornus 1 and is displaced in the non-surfer-, and in the re .-; cn in the axis -i is cunning.
