Is this grinder good for cutting metal?

Yes. With 8.5 amps and 11,000 RPM it handles cutting discs for metal, rebar and sheet, plus grinding and wire-brush work. Use the correct disc and guard for each task.

Does it have variable speed?

No. It runs at a single 11,000 RPM no-load speed. For polishing or work that needs slow speeds, use a speed-controlled grinder or control the pressure yourself.

What size discs does it take?

It takes 4-1/2 inch (115 mm) discs with the standard arbor. That is the most common size, so wheels and brushes are easy to find.

How do I change the wheel?

The guard is tool-free and the spindle lock is raised for easy access. Press the spindle lock, then use the included wrench on the flange nut to swap discs.

Can it run on a household outlet?

Yes. It is a corded 1000W tool that runs on standard US 120V power. Use a heavy-duty extension cord if you work far from an outlet.

Is it for professionals or home use?

It suits DIYers and light professional work. For all-day industrial use, a major-brand grinder with local service and parts is the safer long-term choice.

Our take on the NEWBEAT 8.5-amp 4-1/2 inch Corded Angle Grinder

The NEWBEAT is a corded 4-1/2 inch angle grinder rated at 8.5 amps (1000W) with an 11,000 RPM no-load speed. It covers the usual jobs: cutting metal and wood, grinding and polishing. Its practical touches are a tool-free wheel guard, a slide switch with lock-on, a raised spindle lock for faster wheel changes and a dust-ejection vent design. Against name-brand grinders it competes on features rather than refinement; it suits DIYers and light professional use, while heavy daily work is better served by a big-brand tool with a wider accessory and parts network.
