BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/less cooling) RAPID-CUT specially developed for automatic and quick feed. Optimised cutting geometry + 3 flat sections of the shank leads to: • up to 30% faster sinking than conventional countersinks • up to 40% higher service life Excellent for countersinking in: • High-alloyed chromium steel such as stainless (V2A / V4A) • Acid resistant steel • Steel • Cast iron • Non-ferrous metals 3-flat shank for: – Excellent torque transmission – No slippage in the drill chuck – This results to superior cutting output < 1100 N < 900 N > 10% Si 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
