Chip Control

Drill: Ø 8mm, L/D=5 Work Material: X5CrNiS18 10 (1.4301) Cutting D ata: vc=60m/min, f=0,10mm/rev, a p=19mm

SDM Competitor A Internal coolant (2,0MPa)

Short chips, Partial long chips,

good chip evacuation risk of tool breakage

by poor chip evacuation

Optimal Cutting Forces

10% lower than competitor A
