- Is the Avid Power 4-1/2 inch grinder good for cutting thick steel?
- Not really. At 500 W it is built for light work. Thin sheet, rebar, bolts and pipe are fine with a cut-off disc, but thick plate and long continuous cuts will slow it down.
- What size discs does it take?
- It takes 4-1/2 inch (115 mm) discs with a 7/8 inch arbor, the common size. The spindle is 5/8-11, so standard grinding wheels, cut-off discs, flap discs and wire wheels fit.
- Does it have variable speed?
- No. This model runs at a single 11,000 RPM. If you need slow speeds for polishing or working plastic, look for a variable-speed grinder.
- How does it compare with a 6 or 7 amp grinder?
- A 6 to 7 amp grinder cuts faster and stalls less under load, but it is heavier. This one is lighter and easier to handle for short, light jobs.
- Do I need a battery or charger?
- No. It plugs into a standard AC outlet. There is no battery to charge, but you do need a power source within cord reach.
- What comes in the box?
- Typically the grinder, a side handle and a wrench for changing discs. Discs are usually sold separately, so check the listing for the exact contents.
- Where is the Avid Power 4-1/2 Inch Angle Grinder cheapest?
- At Lowe's, for $63.99, as of our latest check.
