The media could not be loaded. The GEARWAVE Cordless Angle Grinder Kit has quickly become one of my most-used tools around the garage and workshop. Right out of the box you get two 5.0Ah 21V batteries, a charger, 6 different discs, and a solid wheel guard — all of which make this a complete package for anyone who wants a ready-to-go cordless grinder. --- 🔥 Brushless Motor — Strong & Efficient The upgraded brushless motor delivers plenty of power for a wide range of jobs. Whether I’m: Cutting metal pipe Grinding welds and rust Polishing surfaces …this grinder handles everything with confidence. There’s enough torque and speed that it keeps up with corded grinders I’ve used in the past, and the brushless design means it runs cooler and more efficiently, so you get longer runtimes from each battery. --- 🔋 Cordless Convenience — Batteries That Last Having two 5.0Ah batteries is a big advantage. I can work with one battery in the grinder while the other charges, which keeps downtime to a minimum. The batteries hold charge well and power through heavy cutting and grinding tasks without significant voltage sag. The included charger gets them back to full quickly. --- 🛠️ Accessories & Usability This kit includes 6 discs (cutting and grinding) that cover most common jobs right away, so you don’t have to go find extras immediately. The wheel guard installs securely and does its job keeping sparks and debris away from your hands without getting in the way. The ergonomic grip feels comfortable, and the overall balance of the tool makes it easy to control even on precision grinding or polishing tasks. --- 👍 What I Liked Most Powerful brushless motor — strong enough for serious jobs Dual 5.0Ah batteries — long runtime and less downtime Comprehensive kit — charger, guard, and discs included Great cordless convenience — no cord to trip over Comfortable grip and solid build quality --- ⚠️ Minor Cons Slightly heavier than compact angle grinders (expected with bigger batteries) Discs included are basic — upgrade for specialized jobs --- 🧠 Final Verdict The GEARWAVE 21V Cordless Angle Grinder Kit offers excellent performance, battery runtime, and value — especially considering the accessories you get. It’s powerful enough for cutting, grinding, and polishing, yet convenient and portable thanks to the cordless design. If you’re tired of dragging cords around or want a capable grinder to add to your toolbox, this one delivers on strength and convenience. Highly recommended!

This is a great low-cost option cordless angle grinder. It does feel a little cheap and plasticky, but still works great for the occasional cuts and polishing, which is how I'm using it. I'm not a professional or commercial-grade user, so it is very good for my light duty work around the house and in my garage. The battery charges up quickly and comes with pretty much everything I'd need, all in a case! Definitely great value for money. Now, it isn't exactly robustly made or close to heavy-duty feeling, so I wouldn't be too rough with it or throw it around. For the price, I expected that, Overall, I like it. Works well!

I received this GEARWAVE cordless angle grinder with two 5.0Ah batteries a few days ago and have used it for two different projects so far. The 21V power system provides plenty of cutting and grinding power for both metal fabrication and concrete work without the performance drop-off I've experienced with some cordless tools. The dual 5.0Ah batteries give excellent runtime, allowing me to complete substantial projects without stopping to recharge. The 4-1/2 to 5 inch disc compatibility works well with standard grinding and cutting wheels I already had in my shop. The tool feels well-balanced and comfortable during extended use, with good vibration dampening that reduces hand fatigue. Battery swapping is quick when one runs low, and having two batteries means minimal downtime during larger projects. The cordless design eliminates the hassle of managing power cords in tight work spaces. Based on my initial use, this appears to be a reliable cordless grinder that delivers the performance and runtime needed for serious fabrication work without being tethered to an outlet.

My husband was very glad I ordered this grinder because he needed something to help replace a tile cutter so he could finish up one project, and his next project involves cutting part of a chain-link fence. Based on what we have seen so far, this seems heavy-duty enough to handle both kinds of work without any problem. It feels powerful, solid, and well suited for real household projects rather than just light-duty touch-up jobs. The brushless motor gives it a strong, capable feel, and having the included discs, guard, batteries, and charger makes it feel like a complete setup right out of the box. The batteries have also been doing a good job. They seem to last through a decent amount of work, which is a big plus when tackling bigger projects. And even if a job runs longer than expected, it is no big deal to recharge and come back for round two the next day. Overall, this looks like a very useful tool to keep around for cutting, grinding, and similar project work. My husband is happy with it, and that alone tells me it was a good pick.
