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

For optimum centring, the following procedure should be followed:

- (1) Flatten the broken male, using the tool
largest size tool or a cutter of the same size.
- (2) Choose a suitable male shattering 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 pieces of the male remaining along the walls using
using a pointed tool.
- (4) When the operation is complete, it is advisable to re-drill the hole with a bit
of the same size as the tapping pre-hole.
