⭐️⭐️⭐️⭐️⭐️ (5/5) This brushless angle grinder is powerful, lightweight, and easy to handle. The battery lasts longer than expected, and the motor runs smoothly even under heavier loads. It cuts and grinds cleanly without overheating, and the grip feels solid and comfortable for extended use. For the price, the build quality is impressive and performs just as well as more expensive brands. Highly recommend for DIY projects and light professional work.

After using this product, I really liked these six aspects of it: 1. Cordless: The cordless design is very convenient to use; a cord would be very inconvenient; 2. Protective cover: Without a protective cover, metal fragments could fly out during cutting and injure the operator. With the protective cover, this situation is avoided and safety is increased; 3. You can lock the speed: This function avoids the need to keep pressing the switch key during cutting, which makes it much easier; 4. Its speed can be set according to different uses; 5. It can clearly display battery power and speed 6. Complete accessories

Very nice grinder. It's a bit crunchy sounding at startup but time will tell if it is due to bad bearing or just is the way it is. The implementation of variable speeds is different than I've seen before so I can't say as to if I like it or not. The use of Dewalt batteries was a good one from multiple aspects. Dewalt makes good tools so the odds are a well equiped shop already have a tool that uses the same battery as this one. This sort of thinking seems to be becoming more common and is a real cost savings for consumers. The ability to use grinding wheels, disks and the thick variety grinding disks is super nice and is accomplished by use of one of two width shields to protect the user. The fastening hardware is a nice touch as well as the really nice and high quality tool provided to tighten down the disks. It comes with a wild variety of disks and stones makes the tools ready to use right out of the box. The soft storage "Bag" is nice too. Many tools like this come with hard cases which are also nice but definately take up more room in an already crowded shop.

When a disk was installed on this machine it didn't have enough power to grind steel on a flat surface it would start and then quit .Plus it had a bad sound in motor like it had no lubrication. Every poor quality

The grinder works good with my Dewalt battery, I was going to buy a Dewalt grinder but the price around $200 plus tax, this grinder price not even 1/4 of Dewalt grinder, I got Dewalt tools and battery that’s why I bought this grinder because it works with my Dewalt battery. I changed my shower valve from 2 handles to one handle, I had to use grinder to cut the wall, it worked perfectly and safely. When you off the power it stops fully in 2 seconds. Also the package come with 4 blades it’s very valuable.if you like me have Dewalt tools and battery you better have one with you.

I had hoped this to be a good tool for my husband but unfortionately it is mediocre at best. All the heads to pick from was nice, the bag seems a good quality but the handle doesn't screw on straight. The post that screws into the tool to hold the handle on is not center to the handle and because of that it wobbles a little, so when you go to use it you're worried its going to break! Not a good design for a hand tool.
