With extremely high rotational accuracy and optimal power transmission via belt drive for three different speeds. The unit offers a high quality machined work table of ribbed die-cast aluminum (work table size 8 1/2" x 4 3/4" (220 x 120mm)) providing an adjustable parallel fence with scale. The solid, hard-chromed steel column is 11" high (280mm) and has a diameter of 4/5" (20mm). The powerful motor, which is built into the super stable die-cast head of the machine, runs very quiet and has a long life expectancy. The power transmission by 3-step aluminum pulleys and flat belt provides 3 spindle speeds of 1,800, 4,700 and 8,500rpm allowing triple torque at lower speeds. The chrome feed lever has a practical adjustable drilling depth gauge. The spindle is essentially free of play as a result of the three high quality ball bearing assemblies. It is recessed for the insertion of MICROMOT steel collets, but also threaded for attaching drill chucks with 3/8" thread. The spindle has an extremely high rotational accuracy and a 1 3/16" (30mm) feed. The quill diameter is 1 1/4" (32mm) with return spring, the throat depth (column to drill spindle) is 5 1/2" (140mm). The unit provides quick coarse height adjustment of the headstock via clamp lever. The max. height (worktable surface to spindle end) is 5 1/2" 140mm).
