GENERAL COMMERCIAL 75-510 M1 UPRIGHT DRILL PRESS

The General Commercial 75-510 M1 Upright Drill Press features a robust 20-inch swing and a 1-1/4 inch drilling capacity in mild steel, powered by a 1 HP brushed motor running at 120 V and 10 A. It offers a mechanically variable spindle speed range from 280 to 2100 RPM, displayed digitally for precision control. The MT3 spindle taper supports a 3/4 inch keyed chuck, with a spindle travel of 4-3/4 inches to accommodate various drilling depths. The cast-iron table includes T-slots and crank-operated rack and pinion height adjustment, providing flexibility and secure setup for workpieces. The distance from table to spindle is 27-3/4 inches, with a base-to-spindle height of 46-7/8 inches, and the machine’s footprint measures 23-5/8 by 15-3/4 inches, weighing 284 lbs for stable operation. Essential features include an adjustable spindle tension return spring, positive depth stop for repeatable drilling, a see-through flip-up chuck guard, built-in lamp (bulb not included), and a built-in laser pointer for accurate alignment. Safety is enhanced by a forced opening line interrupter switch requiring a restart after power interruptions. This drill press’s heavy-duty construction, smooth vibration-free operation due to high-quality bearings, and convenient ergonomics make it well-suited for commercial and industrial workshop use.
