Groz HMR/IPW/3-4/STD Hammer – Spare for IPW/401

The Groz HMR/IPW/3-4/STD is a hammer, a spare part for Groz's IPW/401. Groz's IPW-401 is a 3/4" drive impact wrench built for tyre service, wheel alignment and similar repair work, with a twin-hammer mechanism that Groz also rates up to 2522 Nm (1860 ft-lb) of torque. The hammer is the internal striking part that delivers the rotational impact blows which give the tool its driving torque. Because it is sold on its own, only this part needs replacing when it wears out, rather than the whole assembly that houses it.
