This series of drill bits designed for drilling FR-4 circuit
board materials feature common 1/8th in. shanks. The
drill element is fabricated of solid carbide and the shanks
are stainless steel. Carbide is the preferred material for
drilling glass epoxy circuit board laminates due to its
exceptional hardness. Unlike high speed steel bits which
become dull quickly, these carbide bits are capable of
several hundred or even thousands of hits before
significant degradation of sharpness*. Designed for high
speed equipment operating up to 80,000 RPM, these
drills can also be used at lower speeds by using a slower
feed rate. Due to the brittleness of carbide these drills
are recommended for drill press use or use with
precision equipment. Care must be taken not to drop or
flex them as breakage may occur. Use these bits to
make your own printed circuits or modify SURFBOARDS
surface mount breadboards or other types of boards.
While designed for printed circuit use these tools may be
used with other materials such as plastics and metals.
The user is advised to evaluate the suitability for any
given use by trial and possible adjustment of speed or
feed rate.
* The number of holes that can be drilled is dependent on a number of factors
including feed rate, speed, material characteristics, and what the user considers
acceptable hole quality.
