Just like the RMT 4123 series of chipping hammers, the RMT 4125 series of Chippers are available with 2”, 3”, and 4” cylinder options and also with bushing choice of “Round” or “Hex”. Its unique ring valve design provides harder blows in tough conditions. The spline locking system is there for extra safety as it prevents the loosening of the handle or cylinder. Chipping Hammer has the same features as lightweight, compact yet powerful. This too has a pistol-grip handle with a self-closing outside trigger.
