The Chicago Pneumatic CP 4125 is a 16 lb 4-bolt D-handle pneumatic chipping hammer with a 4 in. piston stroke, purpose-built for industrial scaling, chiseling, weld cleanup, and form stripping. Key specs include 2,400 BPM impact rate, 25 CFM consumption at 90 PSI, .580 in. hex or .680 in. round chuck options. Ironworkers, masons, refractory crews, and demolition contractors run the CP 4125 for medium-duty chipping where heavier breakers cause operator fatigue.
- 4-Bolt drop-forged D-handle construction balances tool weight and rigidity for sustained overhead and one-handed scaling work.

- Built for scaling slag and rust, weld-spatter cleanup, form stripping, refractory-lining repair, mortar removal, and detail chiseling.
- Ironworkers, masons, refractory crews, and demolition contractors specify it for medium-duty chipping where heavier breakers cause operator fatigue.
- Crowder Supply stocks .580 in. hex and .680 in. round chipping steels plus replacement chucks, retainers, springs, and pistons for the CP 4125.
