The Tamco/Toku TCH-4 is the 4-cylinder heavy hitter of the TCH series: a 4 in. stroke chipping hammer that trades blow rate 1,600 to 1,800 BPM for the deeper impact that harder concrete and thick scale demand. The 20 lb four-bolt body carries a drop-forged handle, heat-treated alloy steel cylinder, replaceable chuck bushing and exhaust deflector, the same construction as the rest of the pneumatic chipping hammers we stock.

Run it on 33 CFM at 90 PSI through the 7/8-24 inlet and a 1/2 in. hose, with the .580 in. hex or .680 in. round chuck selected on this page. Long-stroke hammers shine on demolition-adjacent chipping; when the job is genuinely breaking, step up to a paving breaker. Matching chisels and moil points ship from the same Denver shelf, and the chipping hammer guide covers when a 4 in. stroke is the right call.

TCH-4 FAQ

What steel fits the TCH-4?
Order it with the .580 in. hex or .680 in. round chuck and run matching-shank chisels and moil points; the standard retainer is an oval collar with spring, and the chuck bushing is replaceable.

TCH-3 or TCH-4 which one do I want?
The TCH-3 runs a 2-1/2 in. stroke at 2,0002,200 BPM for faster, lighter blows; the TCH-4’s 4 in. stroke at 1,6001,800 BPM trades blow rate for the deeper impact that hard concrete and thick scale demand.

How much air does it need?
33 CFM at 90 PSI through the 7/8-24 female inlet on a 1/2 in. hose feed it oiled air through a whip or inline oiler to protect the 1-1/8 in. piston.

Who makes the TCH series?
Toku, the Japanese pneumatic-tool manufacturer whose industrial chipping, riveting and demolition tools carry the Tamco/Toku badge here.
