The Chicago Pneumatic CP 4130 is a 3-cylinder pneumatic chipping hammer a 3 in. stroke, 1,900 BPM tool in an 18 lb heavy-duty D-handle body built for sustained chipping, scaling, form stripping and concrete demolition. With a 28 CFM draw and 1 in. bore, it sits between the light CP 4123 and the 1-1/8 in. bore production hammers in the Chicago Pneumatic chipping lineup.

A 19 in. overall length adds reach for floor and form work, and the teasing throttle meters single blows when a chisel needs to be walked into a seam. It takes .580 in. hex or .680 in. round steel, chosen on this page.

CP 4130 FAQ

What does 3-cylinder mean on a chipping hammer?
Cylinder count is trade shorthand for stroke class — a 3-cylinder hammer runs roughly a 3 in. stroke. The 4130 pairs that stroke with 1,900 BPM for the mid-range balance of blow energy and cycle rate.

How much air does the CP 4130 draw?
28 CFM at 90 PSI, fed through standard contractor whip hose with an inline oiler in the line.

Which steel does it run?
.580 in. hex or .680 in. round shank, with ball, oval-collar or bolt-on retainer styles to match the construction chipping steels you already own.

When is the lighter CP 0012 the better pick?
When precision beats power: the 12 lb CP 0012 cycles a 2 in. stroke at 2,600 BPM on only 20 CFM for trimming, weld scaling and detail chiseling.
