Ryobi Bench Grinder: Quick, Honest Review
If you’ve gone too long without a bench grinder and want a simple setup for cleanup jobs, the Ryobi bench grinder might look tempting. I ran it through a real task: stripping paint and rust from a boat mounting plate.
What you’ll get:
- A no-frills grinder that can wire-wheel light rust and paint
- Usable guards and a work light (AAA-powered)
- Noticeable limits under pressure and longer runs
Tools & Materials
Setup that actually works
Swap one grinding wheel for a wire wheel using the left-hand thread on one side: turn the left bolt clockwise to loosen, the right counterclockwise. Use the included spacer and flanges in order, then snug it with a 3/4 inch wrench. Reinstall the guards before power-up, and mount it to a bench if you can—the tool walks under load and that hurts performance and control.
Power and stall behavior
This unit will stall if you lean on it. It spins, it cleans, but pushing hard slows it quickly. Keep a light touch and let the wire wheel do the work. Expect warming after about 10 minutes of continuous use; take breaks and don’t force it.
Where it shines vs where it doesn’t
- Shines: knocking loose flakes, smoothing edges, and taking off light rust or overspray.
- Struggles: heavy-scale removal or aggressive material takeoff. For tight spots and stubborn sections, you’ll still reach for a drill-mounted wire wheel or a Dremel.
Safety and comfort
Wear safety glasses and cover up—wire bristles shed. A shop apron helps keep stray wires out of clothing. Keep your workpiece planted and use the rests and guards; unmounted grinders can shift when you push.
Should you buy it?
It’s fine for occasional, light duty cleanup and sharpening. If you expect frequent, aggressive grinding or wire-wheeling, look for a higher-amperage unit and bolt it down from day one.
Bottom line: usable for light tasks, but underpowered if you need speed and staying power. Mount it, use a gentle touch, and keep a drill or Dremel handy for the rest.
