Titanium drill bits last 6 x longer than high speed steel bits. The durability comes from super hard titanium nitride coating. This coating protects the bits from chipping and cracking and the lubricity protects from heat build-up which is the number one cause of product failure. The speed helix design penetrates 3 x faster than standard bits for easier drilling, reduced heat, extended drill bit life and extended battery life. 135° split point starts on contact with no walking or skating.
