Genuine Blacks Charpy/Izod Notching Broaches

Our broaches meet most standards i.e. BS, ISO, EN, ASTM and many other International Standard notch profiles.

Due to the variety of broaches and notch configurations, broaches are ordered separately.

All broaches, which have a unique serial number, are tested to ensure that they cut the correct form before despatch and a Certificate of Conformance is issued with each broach.

Special notch profile broaches may be supplied to order, send details for consideration, please specify:

Notch type
Depth of notch
Applicable standard
Material specification/Hardness Rc
 

Standard Broaches – Our standard broaches are designed for use on carbon steels up to 42 Rc.

Hard Cut Coated Broaches

This is a superior broach to the standard broach and is recommended for use on our Variable Speed Machine for tougher, harder & stainless steel materials to extend tool life.
If used on our Hand Machine, tool life is dependant on a smooth cutting action by the operator & the machining difficulty of the material.

 

Broach Regrind Service

We also offer a broach regrind service. Please note this is dependant upon the condition of the broach. We only grind the land (cutting edge) and not the form. Generally if the form is worn or more than one tooth adjacent to another are broken then it may not be practicable to re-sharpen the broach.
