Through hole machine tap Garant for copper M 60 HSSE PM With the latest generation of DLC coating sp2. Very sturdy design, with spiral point and special cutting edge geometry for copper materials. For use with emulsion (fat content minimum 8%). The spiral point evacuates the swarf in the cutting direction.

The reference material (in Europe) for comparison is the lead-alloyed free-cutting brass CuZn39Pb3. This is the reference material with the assigned machinability index 100. The machinability index is a measurement for the productivity that can be achieved with a specific material in series production when directly compared with another material. Machinability indices for copper alloys are issued by the German Copper Institute and by material suppliers. Classification of machinability into 3 main groups Working life Chip formation Cutting forces Surface quality The classification was made primarily in regard to the expected chip building. However, for the difficult-to-machine materials in Group I wear on the tool is the key feature for the classification. the high level of Machinability Group I Copper materials containing lead, tellurium or sulphur, homogeneous or heterogeneous structure. Very easy to machine. Machinability Group II Copper materials with higher tensile strength and better cold forming characteristics, long chipping. Good to moderate to machine. Machinability Group III Copper materials with homogeneous structure. Good cold forming characteristics lead to poor chip formation (long tough chips) and high tool wear. Difficult to machine. i II m index Index Index 100-70 60-40 30-20 V J I ’ Main catalogue Hoffmann Group 46 129 DIN 371 -SM10 DIN 376 SM12 ISO DIN 13 ISO 2 6H i 3 i <3xD Version
