Carbide Hole-Starting Drill Bits
90° Point Angle
120° Point Angle
140° Point Angle
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°.

Electrical Discharge Machining Tube Electrodes
With One Channel
With Two Channels
Create very small holes, including pilot holes to run EDM wire through. For use in hole-popping EDM machines.
Also known as spark machining, electrical discharge machining (EDM) uses electrical current to erode a metal workpiece to a desired shape.
Brass electrodes can be used at a faster machining rate but wear out quicker than copper electrodes.
Copper electrodes last longer and are better for use on extremely hard materials, such as carbide, sintered diamond, and invar and kovar nickel alloys.
Electrodes with one channel are best for creating through holes.
Electrodes with two channels are best for creating closed-end holes. The internal channels disintegrate material left at the bottom of a closed-end hole.
