For countersinking in: → Abrasive and hard steel with a strength of over 1000 N/mm2 → Gray cast iron over 240 HB → High-alloyed chromium steel such as stainless (V2A – AISI 304 / V4A – AISI 316) → Acid resistant steel → Titanium and titanium alloys → All further steel sorts, cast iron, non-ferrous metals where maximum tool life are desired. Pilots provide great stability and accuracy. If drilling without pilots, please ensure that the countersink is adjusted centrally to the drilled hole. These countersinks comes fully assembled with: → 4 pieces of carbide coated inserts, including 4 TORX mounting screws and 1 TORX wrench. → The triangular inserts are rotatable. This means all 3 cutting surfaces can be used for 3 times more tool life. → See suitable pilot pins below. < 1400 N < 900 N > 10% Si INCH 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
