The GA5020 is engineered with Makita's innovative Super Joint System (SJS) to protect the gears for longer tool life.10.5 AMP Motor Delivers 11,000 RPM The GA5020 is powered by a 10.5 amp motor that delivers 11,000 rpm, with electric brake for maximum productivity. The labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. In addition, the armature is sealed by a protective zig-zag varnish which prevents contamination by creating a barrier under rotation.Super Joint System (SJS) Protects the Gears The GA5020 is engineered with SJS, an innovation from Makita that protects the gears by automatically disengaging the gears from the motor should the grinding wheel accidentally catch or bind.Comfort and Ergonomics The GA5020 weighs just 5.9 pounds and is built with comfort and ergonomic features for extended use. The ergonomic rubberized handle with trigger switch provides easy operation, and the gear housing can be positioned every 90 degrees for operator convenience. In addition, the side handle can be easily installed on either side of the tool.Versatile Design for a Range of Applications The GA5020 is a versatile and powerful grinder engineered for demanding applications including cutting, ferrous metal, paint and rust removal, shipyard maintenance, heavy machinery, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, and restoration work.

The GA5020 is just another example of Makita's commitment to innovative technology and best-in-class engineering.About Makita's Super Joint System (SJS) Super Joint System (SJS) is an innovation from Makita engineering where the motor armature and spiral bevel gear are linked by a coil spring. If the grinding wheel catches or binds, the coil spring relaxes and disengages the gears from the motor. As the grinding wheel stops, the gears and motor are protected.

  • Powerful
This grinder is powerful. Not like your battery operated ones. Just make sure to use the support handle if you need it. It will try to jump out of your hand.

  • Braking System
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. ... show more

  • Buy Once Cry Once and Your grandkids will inherit a great angle grinder too!
Buy once, cry once. This is coming from someone with limited funds who often does buy and love Wen, Harbor Freight, or China direct. But at this price this is indeed a DEAL. This model lacks the OSHA compliant thumb press trigger lock mech so if you intend to use this in industry go for the model that costs $7 more but for hobbyists this is the way to go. Just be careful putting it down but the trigger has a very satisfying and heavy snap action, so “self-actuation” would fall under the category of user error in my opinion. The trigger itself is a good name brand button everything on the inside of this thing is extremely well made and tough as nails. After months of use there’s been very little ingress of dirt into the head assembly or casement anddd ummm yeah just buy it. It’s one of those tools that makes you say things like “say hello to my little friend” and “That? That’s not a knife... THIS IS A KNOIFE” ... show more

  • This one was junk!
I'm surprised by this burning up after a month and half. I work in a shipyard doing steel construction and have seen multiple employees us earlier models of the same thing as this one. For some reason this did not last long and it is not just the bushing inside that are the issue. Pretty disappointing for a Makita at this price... ... show more

Great grinder. Grinding is not fun,, I've got corded and cordless grinders from 4 inch to 9 inch, this one is my favorite. Much lighter than my 7 inch.
