RMT 4130 series of chipping hammers has a locking mechanism with four bolts, which gives higher airflow and ease of service to the tool. It comes with a `D’ handle with the outside trigger. RMT 4130 series 4 bolt chippers are available in 2”, 3”, and 4” cylinder options and with “Round” or “Hex” shanks to choose from. Hex shank prevents chisel rotation. This chipper comes with a muffler assembly. Its unique ring valve design provides a harder blow in tough conditions. The spline locking system is there for extra safety as it prevents the loosening of the handle or cylinder.
