Hitachi G12SR4 6.2-Amp 4-1/2-Inch Angle Grinder with 5 Abrasive Wheels (Discontinued by the Manufacturer)

for the price it is a great little grinder.upgraded review to 5 stars and i have ordered another one... seems the name has been changed to metabo HST .I have used this up to about two hours at a time stopping only to put on new cut off discs and flap discs...The face that it has not overheated or simply given up is amazing when you consider the price.I don't put a lot of pressure on the machine while using it and if you really lean into it it will slow down after all it is just a 6 amp grinder... But it can certainly grind through 1/4 inch plate which is about as thick as most of us DIY types deal with...I paired one of these grinders with a northern tools grinder stand (16 bucks) and got myself a handy dandy cut off saw for small stuff like rebar and small tubing....I also use grinder to cut long straight strips off steel plate ... just using a bit of angle iron as a straight edge until i have nice groove to follow...useful tool, the case is too small... i picked up a soft tool bag big enough for a couple of grinders and another bag for the discs...

Wow. This angle grinder works great. I used it for the first time the other day with a Skil grinding disc to clean up some rusty metal for welding. It just plain and simple worked great. TBH I dont really know for sure if it was the angle grinder or Skil grinding disc that made such any easy experience or perhaps the combination of the two. But whatever the case it did a great job I was very impressed. I also own a Skil angle grinder as well have only used harbor freight grinding discs and cut off wheels with it. It came with a Skil grinding disc but had never used it.In short this angle grinder does a great job. It come with a hard shell carrying case as well which includes room for its handle wrench thing and molded to hold and protect several discs as well. I filled mine with three cut off discs, three flap discs, and two grinding discs one left on the grinder.The only complaint so far is that the plastic case is very thin plastic... say in comparison to my ryobi case (for those tools) it is MUCH thicker and robust... but again tbh the case that came with the Hitachi angle grinder should hold up (if treated decently) and definitely does the job of organizing and protecting the angle grinder, handle, wrench thing (both of which I never use) and discs.Good stuff. Highly recommended.

A quality product that is affordable for casual and medium users. I have never used an angle grinder before. After some initial confusion primary due to the senseless User's Manual I got the hang of it quickly.I bought this grinder to remove a flange on the tailgate of an old Ford F-150 I am restoring. I planned on having the auto shop do it for me. However, when they quoted me a $125 price I decided upon this $45.00 grinder. I also bought the recommended DeWalt cutting discs.Now that the tailgate project is complete I'm looking for additional projects. "Look out house, here I come!"

This is a good price on a good grinder. The case and accessories are nice. It doesn't have a ton of power, but I guess you get what you pay for. I bought it for grinding thinset with a 4" diamond cup wheel. The grinder bogged down a lot and got hot quickly. I gave it several breaks for the job to cool down. My $15 dollar grinder that I bought over a decade ago from Big Lots seems to run cooler with just as much power, but the thing is about to fall apart. Anyway, the grinder is easy to handle and got the job done, so I give it 4 stars.

Keep in mind that I don't use this grinder for heavy, daily work on the job. This is used mainly around the shop and occasionally in the field for light to moderate rust removal, cutting, grinding, etc...Very pleased with the construction of the unit. Solid and well made. Not so happy with how the on/off trigger works as I just cant quite get the knack of turning it on the first time every time... my problem, but still a (minor) problem.Well pleased overall and well worth the good price.

I wondered if this tool would be adequate for the job. It has all the power needed to use wire cup brushes to remove old caulking from the roof of my RV. I ran it for hours with only short pauses for me to rest, and it got warm, but not hot. This is a great tool. Have not used one of the grinding wheels yet. Sometimes I don't get the on/off switch to turn ON the first try, however it always is easy to turn OFF. I can see the advantage of a paddle switch for instant off without having to move finger to the switch, but those units cost much more. Hitachi does not recommend using wire brushes with their angle grinder, but it works great. Really, what else is there that will do the job? I used Weiler stainless steel brushes, full face protection, protective clothing, and am aware of face position relative to the grinder. I would buy this again.

Used it for a 16 week welding class and this thing has held up. Pretty awesome it came with a case and grinding disc. The case is a little overkill in my opinion but its not a bad thing. I have definitely abused this thing, dropped a few times from 3-4 feet and no issues. For the price I am super happy with this purchase.

I bought this with a specific task. I own a 1980 cj5 jeep and I am putting a new suspension on it. The U-bolts were so rusted that they bound up when trying to get the nuts off them. I bought cutting blades, not the grinding you get with the grinder. It has cut through the 1/2" u-bolts and the bolts are smoking hot but the grinder didn't over heat or get hot. I'm glad I bought it, a friend has some of their pneumatic nail guns and they are great.
