The TIN coating on these drill bits protects the bits from wear, increases chip flow in softer materials, and allows the bits to run at higher speeds than drill bits with a black-oxide finish. The bits are made from high-speed steel, which provides some flexibility and absorbs some shock and vibration.

Features:

- Designed for maximum speed and durability

- Pilot point and split point

- No walking - More user control

- Designed for use on hard metals

Brand new. Backed by a 3 year Dewalt warranty.
