"WELL BUILT TOOL JUST A BIT TO BIG FOR THE TIGHT WORK IN THE WORK I WANTED IT FOR."
"Great Tool when you need too cut or grind something big."
"Awesome addition to my tool arsenal."

"I bought some cheap grinding stones and some carbide bits and this thing cuts through anything like butter."
"I don't know if it has a "soft start" feature as such but it does NOT jerk in the hand on startup even with a 3 inch cutting wheel and that really gives you a feeling of control."
"He circled it in a magazine at a local store."
"I use this in conjunction with the saburr carbide burr bits for the purpose of wood carving with modern technology."
"My last one was good for 24 years and only had to go to tool heaven when the plastic around the nose cracked."
"Powerful and durable."
"This is an awesome tool for when you don't want to bother with the air compressor and hose."

"I HAVE 3 OF THESE AND HAD OWNED THIS ONE ABOUT 30 DAYS BEFORE THE BASE WHERE BLADES ATTACHED CAME APART AND REVEALED A COMPRESSION SPRING SPERATION. GUARD STILL DOES NOT WORK AND UNIT CONTINUES TO GRIND WHEN THE ANGLE GRINDER IS IN USE. They noted the issues I was having and said they would send a new angle grinder and would email a UPS label to return the old one."
"I have wanted an angle grinder for a while now, and our concrete sidewalk project helped make it so."
"Big and heavy, but solid and durable."
"I always cheaped out on grinders and every 3 or 4 months I'd be at the budget tool store spending $20 on a grinder after burning mine up."
"Most grinders I take the guard off due to interference with work but this one can be quickly rotated to different position so that it is not a hindrance."
"I have the one step up larger also which will take a large disc but don't use it as much as this one is just easier to grab."
"Faced with clogged, worthless sandpaper on the belt sander, I knew exactly what tool combination I needed, and this Angle Grinder with a high speed wire brush did not disappoint!"

"At first glance it seems like a decent grinder, but there is a lot of vibration on my workbench when its running."
"It has a lot of muscle behind it; so much that it doesn't even start to bog down when I am doing some serious grinding on severely rusted rail road ties and other higher quality knife steel."
"Great grinder, I purchased a 120 wheel at the same time and I am using the 60 / 120 grit wheels."
"Nice grinder for the price even though it is China."
"Mine was damaged in shipping (something amazon needs to work on) due to poor packaging."
"Great bench grinder for the shop!"
"I read the negative reviews and should have heeded the warnings...but I ordered one anyway and it arrived today. But we also found that the shoulder on the shaft that the inside cone washer seats against had a high spot on it. These are simple machines: no gears or complex mechanisms, just a motor with an extended shaft. The Apple computer I'm using to write this review was also made in China and it's a beautifully crafted machine."

Find Best Price at Amazon"I was hooked...I always have 3 grinders; one dedicated to grinding/flap wheels, one to cup and stinger brushes and one to cut off wheels. I was enthusiastic about a cordless grinder with the power of a corded grinder...so much that I almost bought 2 right off, but calmed down and decided to "try" 1 first. I also prefer a support handle with rubber grip...this one is hard plastic like any of the cheapest grinders...it's somewhat petty but I can feel the diffence especially when using a stringer brush and the grinder is trying to run away...based on cost I expect the better handle. I'll buy another one with batteries but might wait until I let the smoke out of one of the corded grinders."
"Compact heavy duty and powerful."
"We own many Dewalt battery operated tools never not been satisfied, this is a great grinder for small projects."
"The first thing I did to test the power and runtime of the grinder was throw on my King Arthur tools chainsaw carving wheels to see how it handled those."
"It met up to my expectations."
"Just blows my mind, DeWalt perfected the tool less replacement of blades on the DC300 and they did not leverage it here?"
