Wall chasers with safety clutch

Safety clutch

— special coupling located between the motor shaft and the spindle; may be disposable or reusable. With a critical increase in resistance on the disk / cutter (for example, if the disk is jammed), this clutch is destroyed or opened, preventing engine damage and sharp jerks of the tool. This type of protection is also found in electric tools and in units with internal combustion engines (see "Type").
