This solid carbide tool is designed to destroy broken taps inside holes.
Machining is normally performed dry.

For optimum centring, the following procedure should be followed:

- (1) Flatten the broken tap, using the tool
largest size tool or an end mill of the same size.
- (2) Choose the appropriate tap-destroying tool and perform the operation, taking care that the
the operation taking care that the rigidity in machining is maximum.
We recommend a cutting speed not exceeding 45 m/min and a
feed rate of 0.03 to 0.05 mm.
- (3) Remove any pieces of tap remaining along the walls using
using a pointed tool.
- (4) When the operation is complete, it is recommended to re-drill the hole with a drill
of the same size as the tapping pre-hole.
