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.
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.
L2 = LC - 1.5 × DC.
Note:
Suitable NC spotting drills No. 112120, 112140 and 112170 with 142° tip angle for enhanced process reliability
