Karnasch Premium drills to remove jammed taps 

Counterboring with Karnasch drills to remove jammed taps saves time and money!

Your tap has broken off and is stuck in the drill hole? In this case, use our solid carbide drills to remove jammed taps.

Karnasch drills to remove jammed taps are made for steel <65 HRC and threads from M3 to M12. They are available in drill depths from 10 mm to 35 mm. 

Approximately 1 to 5 threads can be drilled out with one drill. Due to the cylindrical hexagon shank, the drill to remove jammed taps can not only be used on NC machines, but it can also be clamped in normal three- or four-jaw chucks. When used correctly, all materials, including copper, aluminum and hardened materials, will not damage the core hole.

DRILLS TO REMOVE JAMMED TAPS - USER MANUAL

  1. The workpiece must be clamped very stably.
  2. Plane the projecting part of the drill with the workpiece.
  3. Center the drill by 'tapping' several times. When centering on a CNC machine, select a low feed.
  4. The counterboring process can be performed on an NC machine with lubrication (attention: risk of sticking together), as well as manually on a bench or pillar drilling machine. Repeated chip removal is mandatory on all machines.
  5. Remove any remaining chips after the counterboring process with pneumatic air.
  6. Re-tap the thread with a new drill.
  7. After finishing the thread, check the dimensional accuracy with a thread plug gauge.
