High-Torque Bit Sets

Heat treated for hardness, the bits in these sets won't crack or deform under high torque. They are manufactured to tight tolerances to prevent slipping.

Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).

Wear-Resistant Diamond-Coated Steel—Diamond particles embedded in the tip bite into the screw head for a strong grip. Our most wear-resistant bits, these maintain their grip and shape, even when driving screws into tough materials.

Bit Sets For Impact Drivers

Tougher than your average bits, the ones in these sets have a thin, flexible section on the shank that absorbs 30 times the impact force. They are heat treated for hardness and manufactured to tight tolerances, so they won't snap or slip under high stress.

Hex Shank—Use a bit adapter (not included) to attach these bits to power tools.
