- Is the DeWalt DWE4120 good for cutting metal?
- Yes. The 900 W motor and 12,000 rpm top speed handle rebar, bolts, studs and sheet metal well for a 4.5-inch grinder. It is a cutting and light-grinding tool, not a heavy surfacing machine.
- Does it have variable speed?
- No. The DWE4120 runs at a single speed up to 12,000 rpm. If you need slow speeds for polishing or thin material, look at a variable-speed model.
- What size discs does it take?
- It takes 4.5-inch (115 mm) discs with a 7/8-inch arbor. The guard is set for that size, so do not fit larger wheels.
- Does it come with a handle and guard?
- Yes. It ships with an anti-vibration side handle and a tool-free adjustable guard. Discs are not included.
- Is it safe to use one-handed?
- The slim body makes one-handed holding tempting, but grinders should be gripped with both hands where possible. Use the side handle and eye protection, and let the wheel stop before setting it down.
