The APT 1133 (M1133CN) is the long-stroke, closed-nose rivet buster in American Pneumatic Tools’ U.S.-built lineup. An 11 in. piston stroke on a 1-3/16 in. bore gives extra reach and per-blow energy over the common 6 and 8 in. tools for bridge-deck repair, reinforced concrete demolition and heavy rivet cutting, running 850 BPM in T-handle (39 lb), D-handle or pistol-grip (33 lb) configurations.

Closed-nose construction keeps debris out of the front-end assembly when working rebar and torch-cut steel, and a deep case-hardened alloy cylinder rides in heavy-duty upper and lower sleeves. All three handles take Jumbo 11X rivet buster steel with a .866 in. shank. For moderate sections, the 8 in.-stroke APT 133 cycles faster at 1,100 BPM, and the rivet buster buyer’s guide explains how stroke length trades against cycle rate across our rivet buster range.

APT 1133 FAQ

What is a rivet buster used for?
A rivet buster is a long-stroke pneumatic demolition tool that shears structural rivets and breaks reinforced concrete. The 1133’s 11 in. stroke suits bridge-deck repair and thick sections where the common 6 and 8 in. tools run out of punch.

Which handle configurations are available?
Three: T-handle at 39 lb and 35 in. overall with a 3/8 in. male inlet, plus D-handle and pistol grip at 33 lb and 25-1/2 in. with a 1/2 in. NPT female inlet. All three run 850 BPM and take the same Jumbo 11X (.866 in.) steel.

How much air does the 1133 need?
48–52 CFM at 90 PSI. Keep an in-line lubricator in the whip so the long-stroke piston stays oiled through a shift.

Is the APT 1133 made in the USA?
Yes — American Pneumatic Tools builds it in the USA, and the old MPNs 19060, 18847 and 18846 cross-reference to current APT 1280-series numbers.
