Set of Solid Carbide Jammed Tap Removal Drills, 7 Pieces

Because of hexagonal and cylindrical shank drilling can be performed on NC machines as well as on manual machines with three or four-jaw chucks. 1–5 taps can be removed with one drill to remove jammed taps. Regrinding of drills to remove jammed taps is not economical. Due to the hexagon, this drill can also be clamped in normal three-or four-jaw chucks. In case of correct use the core hole will not be damaged in all materials, also in Cu or AI and hardened materials.
