Product Details
This heavy-duty drill bit kit is engineered for drilling in tough, high-tensile, and work-hardening materials under extreme operating conditions. Manufactured from premium cobalt high-speed steel, it enhances hot hardness and extends drill wear life. The 135° P3 split point design is self-centering, providing reduced thrust and easier penetration, while sizes smaller than .0625" do not feature a split point. The metric sizes conform to DIN 338 overall length and flute length specifications. A straw finish enhances lubricity and allows for easy identification of cobalt drills. This kit is suitable for drilling in stainless steel, tool steel, alloy steel, and titanium. The package contains a total of 12 drill bits and is proudly made in the USA, with a 30-day warranty included.
