Bosch Pilot Bits

  • Pilot bits easily snap into the mandrel without set screws and a threadless design prevents seizing up in the mandrel
  • The system also features a positive lock design to minimize wobble, a common problem with conventional mandrels
  • The Power Change mandrel accepts any 1/4" hex shank power accessory including spade and power screwdriver bits

Bosch Pilot Bits

  • Simply snap the hole saw off the mandrel for easy plug removal
  • When the cup is re-attached to the mandrel, the pilot drill will push the plug out
  • Quick Change bi-metal hole saws feature Progressor Tooth Geometry, combining cutting teeth with specially designed chip-removal teeth for super-fast cutting action in metal and wood
