Rivet Busters CP

CP 4608 D 001 CP Rivet Buster

CP 4608 D

Chicago Pneumatic

The CP 4608 and 4611 rivet busters offer one of the best power-to-weight ratios on the market.  They also have a teasing throttle for precise control. The teasing throttle is part of the Controlled Power System (CPS). Other features of the system are control of blank firing and control over excessive wear. There are also features for control over premature structural breakage. An indicator groove on the lower sleeve shows when it is time to replace the bumper.

All these features have the same objective: to help control the operating cost and avoid unexpected work interruptions.

Originally designed for removing rivets and for various other metal applications, rivet busters are now also used for concrete demolition work and bridge work. They have approximately the same hitting power as a 60 lb (30 kg) breaker but only half its weight.

  • Teasing throttle for precise control
  • Forged steel handle for long working life under tough conditions.
  • Hardened steel piston
