Considering that I use an angle grinder pretty much every single day I'm not sure why it took me this long to upgrade. Rat tail... You'll either love it or you'll hate it. Myself, I absolutely love it. Of course there's going to be times where you need to get in tight somewhere and maybe the 4-inch or 4 and 1/2 in paddle style is going to be a necessity. In my case 90% of the time if I'm cutting metal or cleaning up welds the extra size on this grinder does not affect anything. I had no idea what I was missing. I have always been loyal to Makita, like I said my old one was still good as the day I bought it with daily use for over 9 years. I just wanted to upgrade and try something new. The brake is probably the most amazing thing since sliced cheese. I had no idea what I was missing. The power, the cut speed, the low vibration, the noise, everything is an improved version of my baseline 4.5" model. Cannot recommend this enough.

Recomendado! ### ⭐⭐⭐⭐⭐ Braking System *by R***H on December 7, 2020* This equipment is akin to a Roll's Royce of grinders. I have another one, a 4 1/2" Metabo HPT and this thing blows that out of the water by far, granted this is 3 times the price. The braking system is the highlight for me due to the short amount of time it takes for the disc to completely stop, the quick adjustable guard is amazing, which also means you won't throw away the guard, the soft-start means your beginner buddy won't be intimidated by the initial kick of the grinder and makes it safer if you forget to let the RPMs reach max before putting on work coupled with the SJS system, and the ergonomics is my favorite. I am big fan of the deadman's switch trigger, rather than the paddle-style or press-and-slide of the Metabo. Although this one doesn't have a safety lock, if you're not worried about OSHA, this is one sweet grinder. 11K RPM means you'll be able to get a lot of 5" and 4 1/2" discs on this pretty easily. All in all, this is a pretty sweet grinder and its power means you can throw most fabrication jobs at it and it'll chew it up rather quickly. ## Frequently Bought Together - Makita GA5020 5" SJS Angle Grinder, with AC/DC Switch, Blue - Makita GA7021 7" Angle Grinder, with AC/DC Switch - Makita 9005B 5-Inch Angle Grinder , Teal --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/13284447-ga5020-5-sjs-angle-grinder-with-ac-dc-switch-blue](https://www.desertcart.pl/products/13284447-ga5020-5-sjs-angle-grinder-with-ac-dc-switch-blue) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-12*
