FORMAT Solid carbide 3xD precision drill type 1208

Design: solid carbide, DIN 6537.
TiAIN coated surface, right cutting, with special point geometry and ratio point thinning. Normal angle of rake, core thickness thicker than normal and without core gradient. Drill with internal cooling. The drill has a very good self-centring behaviour and produces short chips, even from long-chipping materials.

Application: For accurate alignment drilling with very narrow Ø tolerancesand good surfaces. Suitable for drilling holes up to 4 x D with high cutting values. Particularly suitable for high alloy AlSi alloys and alloy steels up to 1400 N/mm² in strength.
