Carbide Hole-Starting Drill Bits
Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. 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.
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°.
Bits with a 140° point angle are for starting a hole that will be followed by a drill bit with a point angle from 118° to 135°.
