This is a solid, versatile bench grinder for your home workshop or garage. It has a 6-inch diameter grinding wheel on each side: one with a coarse 36-grit for heavy material removal and shaping, and one with a finer 60-grit for sharpening and finishing. The big feature is the variable speed control dial on the front. You can adjust the wheel speed anywhere from 2,000 RPM up to 3,400 RPM, which is great because different tasks (and different materials) work better at different speeds. It's powered by a reliable 2.5 Amp induction motor. The tool rests are adjustable and the left one even has a special notch milled into it to help you hold drill bits at the correct angle for sharpening. The base is sturdy, and it comes with eye shields for safety (always wear safety glasses too!). Overall dimensions are about 14.5\ wide, 11\ deep, and 11\ high. A great all-around tool for sharpening lawn mower blades, chisels, axes, cleaning up weld beads, or just general metal grinding. A workhorse for any DIYer.
