    Combination Drill and Countersinking Tool.

  • Drill and countersink in one operation!
  • Highly recommended where counter sinking must be perfectly aligned with drilled holes.
  • Rigid tool holder and cutter heads encase nearly the entire drill for outstanding support.
  • Positive stop screw in the shank provides drill length adjustment.
  • Dual set-screws in the cutter head provide secure support and driving force.
  • Robust cutter heads can be sharpened repeatedly and are easily replaced.
  • Sink-Bits are available from 1/8" to 1/2" and 3mm to 13mm, with countersink angles of 82° or 90°. Other angles available on special order.
  • Sink-bits can be made available at special angles other than 82° or 90°.
