One of a range of basic machines tools made by the Denbigh Company Ltd. of Horseley Heath, Tipton, in Staffordshire, the "Swiftcut" mechanical hacksaw was of ordinary design and similar in appearance and weight to the smaller Rapidor of Manchester models. Offered during the 1950s and 1960s, it appears to have been the only saw manufactured by Denbigh and was listed in two capacities: 6-inch and 8-inch - though each was of identical design and construction. While the 6-inch had a capacity 6 inches on round bar and 6 inches by 4 inches on square and other sections at a 45 cut, the corresponding figures for the 8-inch version were 8 inches and 8 inches by 51/4 inches. Each model could be had for either flat-belt drive by factory line shafting (or a remote countershaft) or as a self-contained unit fitted with an electric motor and drive by V-belts. When supplied as the free-standing version, the 6-inch was fitted with a 3-phase, 925 r.p.m. 1/2 h.p. motor and a simple 2-step pulley arrangement that gave speeds of 70 and 130 r.p.m. (oddly, through probably a misprint, an early catalogue has the figures as 125 and 135 r.p.m.) The 8-inch, equipped with a 925 r.p.m. 1 h.p. motor made do with a single speed of 125 r.p.m.
Both bow and arm slides were finish ground, a standard-fit, automatically activated coolant system was fitted to both self-contained and remote-drive models and a swivelling machine vice, marked with settings of 90, 75, 60 and 45. was part of the standard equipment. Blade feed was damped by the usual oil-filled dashpot, this being arranged to lift the blade slightly on the return stroke. On the electrically-driven model, at the end of the cut an arm, operating through a link, caused the push-button starter to cut the motor. However, on the remote drive version, as not motor was fitted, the automatic stop was arranged through a mechanical linkage.
Although some small differences in specification occurred during the years of production, the three surviving sales sheets reproduced below should show all the differences.
In 1967 the maker'price sheet listed the saw at 128 : 1s : 0d for retail buyers and 108 : 18s : 0d to merchants. A push-button starter was an extra 4 : 2s : 0d and a floor-standing, roller-equipeed work rest, to support long jobs available for an extra 3 : 1s : 0d.
