Description
Version:
Straight major cutting edges and a special flute profile ensure good chip evacuation. The robust cutter geometry ensures high-performance drilling with good process reliability. A wide range of applications in steel materials thanks to a combination of tough ultra-fine grain carbide and extremely wear-resistant coating.
Note:
Flute length LC = L2 + 1.5 × DC.
HB and HE shanks are available at the same price as HA.
For HB shanks: use order no. 123304.
For HE shanks: use order no. 123309.
For process reliability when using the 12×D drill, an initial centre drilling with NC spotting drills No. 121068 - 121130 or HOLEX Pro Steel No. 122501 is necessary.
