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.
