Description
The MPT MDG5003 is a professional electric die grinder for precision grinding, deburring, polishing, and engraving. Its 500W copper-wire motor spins at up to 30,000 rpm. With mounted points, carbide burrs, or polishing bits in the 6 mm collet, it produces fine, detailed results on wood, stone, and metal. The output shaft is high-precision with minimal runout, so the tool stays accurate in detailed engraving and shaping. It has an aluminum head housing that dissipates heat well during extended use. The dust-resistant motor has a wound rotor and coated stator. External carbon brushes in copper brush holders make maintenance quick and easy. A soft rubber grip gives comfortable control, and the body follows the design of MPT’s Bird Nest Series. It suits mold and die makers, metal fabricators, woodworkers, stone carvers, and auto repair shops.
