Jet 578008 Bench Grinder 1 Hp 8 Inch Wheel

Product Description

The JET 578008 is a single-phase bench grinder rated at 1 HP and designed for heavy-duty grinding, sharpening, and deburring tasks in professional shop environments. It spins an 8-inch diameter by 1-inch wide wheel at up to 3,450 RPM, delivering consistent stock removal on ferrous and non-ferrous metals. The arbor hole diameter measures 0.63 inches, accepting standard bench grinder wheels. Operating on 115 volts single-phase power, the unit is straightforward to wire into a standard shop circuit. At 55 pounds, the cast-iron construction provides the mass needed to minimize vibration during operation, reducing chatter and improving finish quality.

The JET 578008 is suited for machine shops, fabrication facilities, maintenance departments, and trade professionals who require a stationary grinding station. Typical applications include tool sharpening, weld cleanup, surface prep, and general metal conditioning. The unit fits on a workbench or dedicated grinder stand and is appropriate for both continuous production use and intermittent maintenance tasks. The cast iron tool rests support precise workpiece positioning during grinding passes.
