Made with Premium 6542 HSS Carbide with a reinforced head to prevent cracking, our twist drill bit sets are made of an impossibly hard, durable alloy.
Our unique U-Slot design allows for fast drilling while removing dust and penetrating deep, while the antiskid triangular handle allows the bit to be held tightly in your drill.
Effortless drilling on any surface: Tile, Concrete, Brick, Glass, Plastic and Wood!
