These bits were used in the production of military spec. high-tech circuit boards.

These boards have extremely tight tolerances and can easily cost $30k+ an order, so we change our bits well before their usefulness has expired to maximize quality.

PLEASE WEAR SAFETY GLASSES AND EXERCISE CAUTION WHEN USING/HANDLING THESE BITS, THEY ARE VERY SHARP!!!

Smaller bits are best used in a drill press / CNC Spindle to minimize risk of breakage

 

We carry many sizes of 1/8" shank drill & Router bits, I welcome your questions...
