- Is the DCG407B worth it over a corded grinder?
- If you work on jobsites without power or move between locations, yes. A corded 4-1/2 inch grinder costs less and never runs out of power, so shop and garage users may not gain much.
- What comes in the box?
- The bare tool only: the grinder, a side handle and a wrench. No battery, charger or case, and no wheel.
- Does it take 5 inch wheels?
- Yes. It accepts 4-1/2 and 5 inch wheels with the standard 7/8 inch arbor, and the guard adjusts tool-free.
- How long does it run on a battery?
- DeWalt rates it at up to 56 cuts of 1/2 inch rebar. Real runtime depends on the pack: a 5.0Ah 20V MAX battery lasts far longer than a 2.0Ah compact.
- What is the difference from the DCG405?
- The DCG407B adds the E-Clutch and Kickback Brake electronics and a slide switch. The DCG405 is the older, simpler model without those safety features.
- When is it cheapest?
- Bare-tool prices swing with promotions. The $115 at eBay as of November 5, 2026 is near the bottom of the range across the four stores listing it new, so it is a fair time to buy.
