The APT 1133 (M1133CN) is the long-stroke closed-nose entry in American Pneumatic Tools' U.S.-built rivet-buster lineup, designed for bridge-deck repair, reinforced concrete demolition, and heavy rivet cutting. Its 11 in. piston stroke gives the M1133CN extra reach and per-blow energy compared with the more common 6 in. and 8 in. rivet busters in the same class.
- Long-stroke 11 in. design with 1-3/16 in. cylinder bore, deep case-hardened alloy steel cylinder, and heavy-duty upper and lower sleeves.
- Closed-nose construction keeps debris out of the front-end assembly during reinforced-concrete and tank-cutting work on rebar and torch-cut steel.
- Delivers 850 BPM at 48-52 CFM consumption at 90 PSI across all three handle configurations.
- T-handle: 39 lb, 35 in. overall, 3/8 in. male inlet; D-handle and pistol-grip: 33 lb, 25-1/2 in. overall, 1/2 in. NPT female inlet.
- All variants share Jumbo 11X (.866 in.) shank, adjustable exhaust deflector, and drop-forged handle construction.
- Built for bridge-deck repair on rebar-laden sections, reinforced concrete demolition, tank cutting, and structural-steel rivet removal.
- Crowder Supply stocks the full Jumbo 11X rivet-buster steel range plus M1133CN cylinders, retainers, valves, throttle assemblies, sleeves, and exhaust deflectors.
- Old MPNs 19060 (T-handle), 18847 (pistol grip), and 18846 (D-handle) cross-reference to APT 1280585272, 1280583179, and 1280583178.
