Let me start by saying, if you're already invested in the DeWalt 20V MAX battery system, this Retek cordless angle grinder is a no-brainer for occasional use. I've put it through its paces on everything from cutting aluminum tubing to grinding down rusty metal, and here's the real deal.

The brushless motor is surprisingly powerful for the price - hitting 8000 RPM without breaking a sweat. What really impressed me was how it chewed through 3" framing nails during a shed renovation project. The battery life? Expect about 20-30 minutes of continuous use with a standard 2Ah battery - standard for cordless grinders.

Now for the not-so-great: My unit arrived with seriously under-lubricated gears (basically dry!). A quick fix with some lithium grease solved the noise and overheating issues, but this speaks to quality control problems. The safety guard adjustment is also annoyingly old-school - requiring a screwdriver when competitors offer tool-less designs.

Where this tool shines? Portability jobs where dragging out cords or generators isn't practical. It's become my go-to for quick masonry cuts when working on landscaping projects. Just don't expect it to replace your heavy-duty corded grinder for marathon sessions.

Final verdict? At about half the price of name-brand options, this is perfect for DIYers who need capable backup tool that plays nice with DeWalt batteries. Just be prepared to do some minor maintenance right out of the box.
