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.
