The Chicago Pneumatic CP 4123 is the light-duty workhorse of the Chicago Pneumatic chipping hammer line: a 13 to 15 lb D-handle tool offered in 2, 3 and 4 in. stroke versions running 2,400, 1,900 and 1,500 BPM respectively. A teasing throttle and air-cushioned piston give fine control for scaling, weld cleanup, form stripping and mortar removal where a heavier breaker would wear the operator down.

Match the stroke to the work the short 2 in. stroke for fast, light scaling, the 4 in. for deeper chipping then pick the .580 in. hex or .680 in. round chuck to suit your steel. Crowder Supply stocks matching chipping hammer chisels in both shank styles, the chipping hammer buyers guide compares stroke lengths across brands, and the full pneumatic chipping hammer range runs from 8 lb detail tools to 4-bolt production hammers.

CP 4123 FAQ

Which stroke length should I pick?
The 2 in. stroke runs 2,400 BPM for fast, light scaling and weld cleanup; the 4 in. stroke trades speed for a harder 1,500 BPM blow on deeper chipping; the 3 in. version splits the difference at 1,900 BPM.

What chisels fit the CP 4123?
Order it with a .580 in. hex or .680 in. round chuck to match your steel, with ball, oval-collar or bolt-on retainer styles to suit existing inventory.

What size compressor does it need?
Air consumption is 22 to 24 CFM at 90 PSI depending on stroke, so a 50 CFM compressor from our air compressor range supports one hammer in continuous use.
