Description
Version:
For producing toleranced holes in steel or short-chipping materials. Reliable complete machining without separate centring and without subsequent reaming process. Significantly improved self-centring due to additional pyramid tip for optimum roundness and tolerance accuracy of the hole that is produced. Two drill cutting edges and four reaming cutting edges for an attractive surface quality of the wall of the bore.
Tolerance specifications:
H7: Version for H7 bore tolerance.
+/− 0.003 mm: Manufacturing or cutting tolerance of nominal ⌀ DC.
