BoschGWG12V-20SB23 12V Max Brushless 1/4 In. Right Angle Die Grinder Kit with (2) 3.0 Ah Batteries

I wasn’t sure if a cordless grinder could deliver the same performance as the pneumatic tools I’ve been using for years, but this device completely exceeded my expectations. It’s incredibly lightweight and portable, making it ideal for tight spaces and jobs where dragging an air hose just isn’t practical.What impressed me the most is its versatility. Whether I’m grinding down welds, removing rust, or polishing steel to a near-perfect shine, this tool handles it all with ease. I’ve used it with 2-inch and 3-inch abrasive pads, and it powers through every task like a champ.The best part? It’s compatible with the battery system I already own, so I didn’t need to overhaul my setup. If you’re looking for professional-grade performance in a portable package, I can’t recommend this grinder enough. It’s a game-changer for anyone who needs power, precision, and convenience all in one.

There’s nothing quite like the ability to grind metal at high RPMs in such a portable device. It’s the size of a pneumatic grinder but without the hassle of dragging around an air hose. Don’t get me wrong—I love pneumatic tools, but I don’t have a powerful enough compressor at home to run them continuously. This grinder is the perfect solution to that problem, giving you all the power you need without being tied to an air supply. It’s a great workaround for anyone looking for portability and performance without compromising on capability.

First task for this little guy was to remove the hardwater ring in my workshop toilet. With the right attachment it worked perfectly to restore the porcelain to like new condition. It is also the perfect size to clean up rust spots on tools. I think this size grinder needs to be in everyone's tool box.

Very convenient for small tasks grinding or light cutoff needs. Quiet, runs smooth and the battery indicator/ speed adjustment on the back of the tool is great. I bought two.

this is for very fine crafts and can also cut off rings or decorative chains (jewellery). It's a nice addition to my 12V Bosch tool set but probably less useful for handywork around the house.

Got it for auto repair/maintenence and woodworking. Amazing torque...I can press fairly heavily using a scuff pad to clean up metal and it doesn't slow down. This is not even comparable to a dremel or drywall cutoff tool. Love the power and 90 degree grip. Variable speed trigger handle works great and easy to keep the speed going. Very happy, worth the high cost.

Have been looking for years for something I could use when the pneumatic right angle die grinder at the workshop was not available.I was open to a corded solution. I never expected anything to come close.I also didn’t want to invest in a different battery charging system, but so glad I did.This tool is amazing. I use it mainly with steel, and 2 inch and 3 inch abrasive padsIt grains down welds with no issue. It removes paint and protective layers. It also handles fine finishing polishes. I just took a larger piece of rusty steel up to a mirror finish.Just so impressed with this tool. Highly recommended.

Excellent quality that you feel just by using it. Great RPM's for such a small tool.
