For general purpose use.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.

These countersinks create a surface that minimizes contact between the material and the lathe centers to prevent damage and allow for more precise machining.

For excellent performance on hard and abrasive materials, these carbide countersinks are harder, stronger, and more wear resistant than cobalt steel and high-speed steel countersinks.

With more heat and abrasion resistance than high-speed steel, cobalt steel is often used on hard-to-machine materials.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.

For excellent performance on hard and abrasive materials, carbide is harder, stronger, and more wear resistant than high-speed steel.

Turn two drive styles with one reversible bit. Remove and replace to change the tip.

Bits have a different size at each end.

Bits have a different size at each end. An opening at the tips accommodates the pin in the recess of tamper-resistant Torx screws. These are also known as pin-in-Torx bits.

Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.
