For countersinking in: → Abrasive and hard steel with a strength of over 1000 N/mm2 → Grey cast iron over 240 HB → High-alloyed chromium steel such as stainless (V2A / V4A) → Acid resistant steel → Titanium and titanium alloys → All further steel sorts, cast iron, non-ferrous metals where maximum tool life are desired. The pilot provides greater stability and accuracy. If drilling without pilots, please take care that the countersink is central to the drilled hole.
