Check your drill chuck and material

Verify that your drill chuck accepts a maximum shank size of 1/4 inch before ordering. Confirm the workpiece material matches the recommended stainless steel, hard steel, wood or plastic applications. Ensure you have a drill capable of the speed and torque required for cobalt bits in harder metals.

Suited for mixed-metal and general use
