The New line of Chicago Pneumatic Rivet Busters replaces the previous models of CP4181 Duler, Duser, Puler and Puser. Some of the key features of the new CP4608 & CP4611 models are listed below.
– Auto Stop System – reduces sleeve breakage & cylinder wear
– Solid Pin on Valve – eliminated valve misalignment
– 1/2" Pipe Thread inlet bushing – swivel can install into bushing
– Longer Piston – hit the steel but not the bridge. Retainer spring will break before cylinder.
– New Rubber Bumpers – 90 durometer rubber recommended
– Teasing Throttle – smooth performance & easy operation
– Florescent Band – an added safety feature for night crews and other applications
– CPS – Indicates when the bumper is worn out and needs replaced
Rivet Buster are extremely powerful tools able to hit as hard as a 60 lb. paving breaker but with half the weight. These tools are ideal for bridge work and meet the necessary requirements for bridge deck repair. These CP tools have many other uses as well from general demolition work or specialty applications such as removing underground storage tanks.
The new rivet busters come in 4 models CP4611D, CP4611P, CP4608D & CP4608P. All models use 45 CFM and weight is relatively the same, between 31-34 lbs. The main difference is handle setup and stroke length which you can determine in the model number itself. 4611=11” stroke, 4608=8” stroke, D=D-handle & P=Open Handle.
