FAMAG Brad Point Twist Drills with Hex Shank

The benefit of a wood twist drill with hexagonal shank is that it can be swapped in a trice in the bit holder. Bit shanks usually have a width across flats of 6.35 mm (1/4 inch). If the drill shank is greater than the bit shank, it can simply be ground down to the correct hexagonal shape. For drill shafts with a smaller diameter there are two ways of fashioning a hexagonal shank:

  1. 1 Fabricate a short bit shank into which the drill bit is inserted and then glued, hard-soldered or welded. This method is cheap but there is the risk that the drill bit will exhibit runout or that it will work loose.
  2. 2 Fabricate the wood twist drill with hexagonal shank from a single piece of steel. For smaller drill diameters a lot of material must be removed which results in higher production costs. This manufacturing method, however, has a positive effect on the running characteristics and the bit shank drill will also last longer because nothing can work loose.
Our supplier FAMAG manufactures its wood twist drills with bit shank as a fully ground version from a single piece of HSS steel. The result is optimal drill bit quality.
