Here’s Why the NoCordz Cordless Angle Grinder Is Our #1 Pick!
After personally testing dozens of cordless angle grinders—from big names like DEWALT, Milwaukee, Makita, and CRAFTSMAN—I kept coming back to the NoCordz Cordless Angle Grinder. While each brand has its strengths, NoCordz offers something rare in this category: the perfect balance of power, portability, and price.
What stood out immediately was how lightweight and maneuverable it is. Unlike the DEWALT and Milwaukee models, which are powerful but noticeably heavy with their 5.0Ah batteries, the NoCordz feels agile in hand—making it ideal for long jobs or tight spaces. It’s also more compact than the Makita XAG26Z, which, while excellent, tends to be overbuilt for small repair or DIY jobs.
In terms of performance, I was honestly surprised. The brushless motor and 10,000 RPM speed packed serious punch—easily handling metal cuts, surface grinding, and even polishing tasks without overheating. While it doesn’t have the raw torque of DEWALT or the advanced tech of Makita’s auto-speed control, the NoCordz held its own beautifully—and did so without the bulk.
Where it really shines is in usability and convenience. Simple controls, tool-free guard adjustment, and quick disc swaps made the workflow smooth. And unlike CRAFTSMAN, which requires more hand repositioning due to its bulkier handle, NoCordz feels naturally ergonomic right from the start.
For pros, it’s a reliable second tool to keep in your kit. For weekend warriors and DIYers? It’s an absolute gem—powerful enough to do the job, yet light enough to actually enjoy using.
If you want a cordless grinder that’s powerful, portable, and easy to control, without paying a premium for pro-only features you may not need, the NoCordz is hands-down the smartest pick of the bunch.
