The American Pneumatic Tools APT 264 is a 4-cylinder pneumatic chipping hammer 4 in. piston stroke, .580 in. hex or .680 in. round chuck that trades blow speed for blow energy: 1,375 BPM lands hard enough for form stripping, refractory removal and light concrete demolition while the 15 lb, 2-bolt D-handle body stays manageable overhead. It anchors the long-stroke end of the APT chipping hammer lineup.

APTs patented automatic ball valve (U.S. Pat. 8,276,682 B2) drives the 1-1/8 in. bore piston, drawing 34-36 CFM at 90 PSI through a 7/8-24 female inlet that takes standard whip hose assemblies a shot of pneumatic tool oil through the line each shift protects the valve and piston. The 2-bolt back-head simplifies field teardown. If you are choosing between stroke lengths, start with the chipping hammer buyers guide, then browse the rest of our chipping hammers.
