Description

Version:

With precision ground point.
Special 4-chamfer relief ground for very good guidance within the bore. Bright finish flutes, nitrided chamfers.
With point geometry shape C.

Advantage:

Special deep hole drills. For particularly deep or recessed holes. Good chip evacuation due to parabolic flutes, resulting in fewer chip evacuations even in particularly deep holes.

Recommendation:

Maximum drilling depth:
L2 = LC - 1.5 × DC.

Note:

Suitable NC spotting drills No. 112120, 112140 and 112170 with 142° tip angle for enhanced process reliability
