Abstract

An accessory for tool machines is provided comprising a tool holder isolatedly carried on bar springs to effect a floating mount. The holder yields in response to selective load stress during cutting and is restricted to a linear force path to relieve stress. The yielding movement relieves stress and can operate signals in the event of overload or operate control means such as switches to cut off tool machine motors.
