The Chicago Pneumatic CP 4160 is the short-stroke entry in CP’s rivet buster family, built for tight-access, overhead and one-handed rivet busting and demolition work. The 6 in. cylinder stroke cycles at 1,100 BPM on 44 CFM at 90 PSI, and both versions the 25 lb D-handle CP 4160 D and the 24 lb open-grip CP 4160 P measure just 20-1/2 in. overall and accept Jumbo 11X (.866 in.) shank steel.

The CPS Control Power System pairs a teasing throttle for precise starts with a Boyer valve and a durometer-rubber buffer ring, while a stepped hardened-steel piston prevents accidental ejection. Both versions of this rivet buster gun run the full Jumbo 11X rivet buster steel range. When section thickness outgrows a 6 in. stroke, the CP 4608 steps up to 8 in.; the rivet buster buyer’s guide compares stroke lengths across our pneumatic rivet busters.

CP 4160 FAQ

What is a rivet buster used for?
Mostly heavy demolition: bridge-deck and parking-garage concrete, tank cutting and drift-pin driving, plus the structural-steel rivet removal the tool is named for.

How much does the CP 4160 weigh?
25 lb in the D-handle version and 24 lb with the open grip both measure 20-1/2 in. overall.

When should I step up from the 6 in. stroke?
When thicker sections need more energy per blow than a short stroke delivers; the full Chicago Pneumatic rivet buster line runs from this 6 in. tool through the longer-stroke CP 4608.
