The short flute and length keep these bits straight for accurate placement when starting holes that will be drilled deeper with a longer bit. Also known as spotting drill bits. Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Titanium-aluminum-nitride (TiAlN) coated drill bits resist wear and temperature better than uncoated drill bits, so they last longer and can drill at higher speeds.

Bits with a 90° point angle are for centering and chamfering holes that will be followed by a smaller drill bit size.

Bits with a 120° point angle are for starting a hole that will be followed by a drill bit with a point angle from 90° to 118°.
