High-performance industrial length drill bits made from M-42 cobalt alloy steel (8% cobalt) with an SP Edge coating engineered for extreme heat resistance, maintaining integrity at 2000°F+ for longer life and higher drilling feed/speeds in tough materials like stainless steel and titanium alloys. The low-friction, high-hardness coating helps deliver up to 40% longer tool life versus uncoated drills in dry drilling while resisting dulling in high-temperature cutting. A 135° split point improves penetration without center punching and helps extend performance in high-tensile materials (Made in the USA).

Super Primalloy® construction ensures heavy duty performance. M-42 COBALT ALLOY with 8% Cobalt content offers superior performance over M-35. Enhanced heat resistance extends service life when cutting tough materials. 135° split point geometry allows for easier penetration. GOLD SURFACE TREATMENT provides excellent lubricity and corrosion resistance. MADE IN THE U.S.A.
