Highspeed spin test of metalworking tools and woodworking tools

Fast rotating tools contain a very high risk potential

If a tool body bursts, as a result of overload or operator error, fragments can spin off with such high speed, that persons in the risk area have no time to react. Common protectors do not offer enough protection against bursting of the tool body.

Woodworking Tools and HSC Metalworking Tools have to be put to the Centrifugal Force Type Test according to Standard EN 847-1+A1:2007 and EN ISO 15641.
