Cylindrical helicoidal drill bits. Rectified double-conoid. 4 cutting edges (2 pairs). Two sharpenings with 135° top angle (external cutters) and 115° (central cutters). 135° sharpening. HSS-G DIN 338 RECTIFIED.
Field of Application:
Highly professional cutting with portable or stationary drills in: steel and highly alloyed INOX steel, INOX steel up to R <900 N/mm2, iron, aluminium and light alloys.
Advantages:
Starting position of cut without problems, avoiding breakage or severe initial wear of the tip due to slipping on the cutting surface. Great improvement in drilling performance for the following reasons: - Pair of central cutters that cut decidedly better than a normal drill bit. - A pair of peripheral cutters that are much more robust and therefore remain sharp for longer. - The presence of a pair of chip breakers: the two sharpening corners at the tip, by crossing each other, create a natural chip breaker that prevents the chips from sticking to the cutters and to the sliding grooves.
