The Chicago Pneumatic CP 4133 packs the 1-1/8 in. bore of CPs production hammers into an 18 to 19 lb body, holding 1,800 BPM in both its 3 in. and 4 in. stroke versions. The high-flow 33 CFM charge delivers the hard, fast blows that heavy chipping, scaling, weld dressing and concrete demolition ask for, in the same 4-bolt D-handle frame as the rest of the Chicago Pneumatic chipping line.
Steel choice is simple: .580 in. hex or .680 in. round chuck, picked on this page, with a moil point for busting and a flat chisel for cleanup covering most days. The 7/8-24 inlet takes standard whip hoses. If you are unsure whether a 3 or 4 in. stroke suits your work, the guide to choosing a chipping hammer breaks it down, and every stroke class is represented in our pneumatic chipping hammer stock.

CP 4133 FAQ
What is the difference between the 3 in. and 4 in. stroke versions?
Both hold 1,800 BPM from the same 1-1/8 in. bore. The 4 in. stroke puts more energy into each blow for heavy chipping and concrete demolition; the 3 in. stroke trades a little punch for control on scaling and weld dressing.
What chisels fit the CP 4133?
You pick a .580 in. hex or .680 in. round chuck on this page, then run any matching shank from our chipping hammer chisels moil points, flat chisels, scaling tools and more.
How much air does it need?
33 CFM at 90 PSI through a 7/8-24 inlet standard for this class, so an ordinary contractor compressor and a whip hose with line oiler keep it fed and lubricated.
