Shopmate 1/2″ Reversible Electric Corded Drill – Model 520 Type 1, 500 RPM, 115V AC

Condition: Used – May show signs of wear but fully functional

The Shopmate Model 520 Type 1 is a classic 1/2″ corded electric drill built for reliable, low-speed high-torque drilling in shop or industrial settings. Operating at 500 RPM and powered by standard 115V AC, this unit is well-suited for tasks requiring controlled, steady power—such as drilling large holes in metal, hardwood, or masonry (with appropriate bits).
With a reversible motor and all-metal construction, the Shopmate 520 is built for durability. Its low RPM suggests it was designed with torque over speed, making it ideal for heavy-duty drilling, mixing, or tapping applications. The 1/2-inch chuck accepts a wide variety of drill bits and accessories.
