Description
Version:
With precision ground point.
Significantly strengthened core without core taper. Bright finish flutes, nitrided chamfers.
With point geometry shape C.
Significantly strengthened core without core taper. 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
