Makita GA7021 7" Angle Grinder, with AC/DC Switch

As far as first impressions, this grinder blew my expectations out of the water. I got the Makita 4 1/2" 10 amp angle grinder (fantastic machine) for Christmas and I've been using it for 5 months now, and it chews through steel like some 7" harbor freight grinders at work, but it feels lighter. That grinder set the bar pretty darn high. So naturally, I went for another beefy Makita when I wanted a 7", and I got this one. (with money from graduation presents, do you sense a trend?) Oh my goodness, I'm so glad I bought this. This thing is a friggin beast. However I'm a small guy (140lb) and I simply cannot effectively grind for long on something if it's not flat, I just can't control it comfortably. But that's why I have my 4 1/2" grinder. But when I have A LOT of flat grinding to do, there is not a single tool that can beat this behemoth. The only thing that can stop this grinder is... well, nothing. Also, this does have a switch locking mechanism. If you pull the safety switch, (in front of the trigger) and pull the trigger to start it, then release the trigger but hold the switch, it'll lock it on so you don't have to hold the trigger down, and to release, you just pull the trigger again. This is awesome, but you do have to be careful, because if it's locked on and you plug it in, it'll hop and around like a rabbit with a broken leg. And it'll scare the crap out of your boss. Ask me how I know. In conclusion, this is a beast of a tool and the weight resembles it. You barely have to put any pressure on it when grinding flat. It lends itself to very fast material removal in a flat position. However, the weight of it hinders any other position, and that is definitely something to consider, especially if you're not a 250 lb barbarian. But I will say it tag-teams well with the 10 amp 4 1/2" Makita. In the end it's well worth the money.

Thus is one real nice heavy duty grinding tool! Used for sharpening mower blades.

use this for buffing on my semi truck, works as it should its a power house!! great tool for aluminum buffing!!

I had several tile projects and for my first project I used a Dewalt grinder that was at least $100 more than this Makita. I sold it, not thinking I would be doing any more tiling. When I decided to tackle one last smaller project, I went with this less expensive Makita. Just like when I had used the Dewalt, I added a dust shroud with the grinder, along with a Dust Deputy and shop vac setup to help contain the dust. The grinder and shroud were nearly half the cost of the Dewalt setup. This Makita worked well for the job. I'd imagine if I went with the Makita originally it would have had no problem handling the 800+ sqft of total floor that needed to have thinset removed. Using this grinder and a cup wheel makes quick work of thinset and it's amazing how smooth and nice the plywood looks after you're done. Just need to vacuum remaining dust and mop the floor to prepare it for the underlayment. Saves buying new plywood if you're existing plywood is in decent shape. At today's cost of plywood and the lesser quality of the materials compared to 15-20 years ago, it's worth the time and cost to save having to rip out and install new plywood. Would not hesitate to recommend this tool!

I had to cut up four 1940s era steel tubs - really thick and heavy stuff, not something you can break up with a sledge hammer like 60s era steel ceramic tubs I've dealt with in the past. I sprung for this unit and it didn't disappoint - went through a few diamond blades slicing those tubs into pieces to pull them out. Felt like a train had run me over when I was done but this unit chewed through them with authority. I've used it for cleaning up steel mesh when taking out walls and the like but it's a bit heavy and unwieldy for working over your head. Granted I'm rocking my dad bod so maybe fitter folks using these would have less trouble. I ended up breaking out my smaller DeWalt angle grinder for jobs needing finesse.

Excelente

It's a beast! Didn't realize how big it was until I took it out of the box. Guess I should have known what with an 1800 W. motor.

An excellent, high-quality, superb tool.

This grinder is awesome it's smooth start takes the strain of your wrist, lot's of power I use it for dressing/ finishing cement just works good

Great product

Tool seems to be well balanced and grips are comfortable. Switch could be easier to engage.

The switch handle dosent swivel...

Works great! Does what I need it to do in good time and without any bitching or moaning! Some Amazon recommended parts didn't fit. But that's an Amazon issue not a Makita issue. However it would seem practical that Makita's universal add ons fit all there respective products. (7" Makita grinder, 7" Makita grinder accessories). I was going to pay more for the Bosch ad it is my brand of choice right now. But when I checked the country of origin they were both China... so I would have paid a premium for a German labeled product that was manufactured in China anyway. 🤷‍♂️
