The Chicago Pneumatic CP 4125 is a 4-bolt D-handle pneumatic chipping hammer offered in 2, 3 and 4 in. strokes 2,400, 1,900 and 1,500 BPM respectively for medium- to heavy-duty chipping, scaling, form stripping and concrete demolition. Tool weight runs 16 to 18 lb by stroke, and each version takes a .580 in. hex or .680 in. round chuck with ball, oval-collar or bolt-on retainer styles.
The 4-bolt back-head puts a 1 in. bore in a stiffer frame for sustained work, and the air draw stays a modest 2527 CFM at 90 PSI within reach of a 50 CFM compressor for single-tool use. It belongs to the same platform as the rest of the Chicago Pneumatic chipping hammers we carry: the chipping hammer buying guide sorts the strokes and frames, construction chisels match either chuck, and the wider chipping hammer stock covers lighter and heavier classes.
