Red Cobalt metal drill bits made from solid, 5% cobalt-alloyed high-speed steel. Designed for use on high alloy steels and metals with tensile strengths over 1000 N/mm², including stainless steel. Features Quad Edge tip that combines a precise 135° split point to prevent walking with four cutting edges that create smaller chips, reducing heat build-up. Features variable flute geometry allowing for fast material ejection and an enhanced tapered web with wider core towards the shank for durability. Enhanced grip and reduced slippage on bits from 5mm in diameter due to 3-flat side shank. 5% Cobalt-Alloyed HSS Round Shank 1mm-13mm Dia.
