The Tamco/Toku RB-91HP is the medium-stroke rivet buster in the Tamco/Toku family, made by Toku in Japan and sold in North America under the Tamco brand. Its 9 in. jumbo stroke (actual 8-15/16 in.) and 1-3/16 in. piston bore handle standard bridge-deck and tank-wall sections at 700 BPM, in 32 lb gooseneck (outside trigger) or D-handle (inside trigger) versions measuring 22-29/32 in. overall.

Construction mirrors the larger RB-110: drop-forged alloy handle, heat-treated alloy cylinder, adjustable exhaust deflector and a built-in safety piston stopper, with a low 36 CFM draw that runs two tools on a 100-CFM compressor or five on a 185. The .866 in. Jumbo 11X shank steel cup chisels, flats and moils is stocked alongside it, and the guide to choosing a rivet buster shows where a 9 in. stroke fits among the rivet busters we stock.
