Its solid build includes a 4.53-inch (115 mm) diameter column and a large, height-adjustable, rotatable cast iron table with T-slots, dimensions around 21.65 x 18.9 inches (550 x 480 mm), suitable for mounting heavy workpieces and fixtures. The drill press offers automatic vertical power feed with three speeds (0, 0.12, 0.18, and 0.25 mm/rev approx.), a fine infeed via precision handwheel with depth scale, and an automatic tapping function with clockwise/counterclockwise rotation. It has a maximum spindle-to-base distance up to approximately 47.24 inches (1200-1270 mm) and spindle-to-table distance close to 29.5 inches (750-754 mm). The machine’s permanent oil bath lubricated gears feature hardened and ground gear wheels for durability. Safety is enhanced by a height-adjustable spindle guard with microswitch.
