Are intended for screw sharpening of drills, three- and four-perforated countersinks and taps with right and left directions of screw grooves, step drills. On the semiautomatic machine it is possible to produce a cutting of the transverse edge at the right and left drills of high-speed steel and hard alloy by abrasive, diamond and elboric circles.

Automated:

• accelerated roughing;
• delayed finishing feed;
• nursing without feed through the time switch with automatic switching to reduced speed of the sharpened tool.
  

Orientation of the drill along the length and angle is made outside the working position during the sharpening of another drill, which shortens the auxiliary time and provides high productivity.

Currently, machines are not supplied, but we are happy to offer you an equivalent.
