Brilliant grinder. You can feel the build quality in your hands immediately. No death rattle. Oil daily like any air tool. If you missed out on the Matco or Snap On tool truck grinder sales, this is your next best bet. If you don't have access to a tool truck, this is your best option.Buy with confidence. It's straight up a quality product.

Used mine for the first time today and it’s just what I needed. Does not bog out at all like most others do. Just hope it lasts for a long time .

Works well. Balanced better than the one it replaced so less vibration with the same carbide bits as before. For best bit and tool life monitor the bit and tool output shaft temp. It is powerful enough to hold speed under heavy load and too much heat will damage your bit and possibly the bearings in the grinder as well.

All day long I'd buy another one and I've always recommended it to other employees. Worth every penny I spent

Fantastic die grinder. All the power you could ask for and top notch build quality. Well worth the price and rivals grinders that cost double, triple or more from tool trucks. Worth every penny and would buy again without hesitation.

This tool is made to work! Wear your safety glasses with this tool. I have a tungsten carbide bit in it and chips fly

I am a trailer mechanic and I need a grinder usually daily. I bought this thing cuz it was the only 1hp I could find at the time. one of the best purchases I've ever made. I let two of the other guys in the shop use it and they both bought one. I use it for everything from cutting siezed fasteners on roll-up door hinges to cutting hardened steel locks. great value tool.*EDIT* I bought another one so I have one at work and one at my shop. They're that good. I don't want to be without it.

Very powerful. Lots of torque. It would be good for somebody with bigger hands. 1 HP means bulky. I will highly recommend it if you take a large to extra large gloves.

This Sunex die grinder is the best I've used. I had an old IR die grinder fail after about 15 years, and bought this and an equivalent Air Cat die grinder as replacements. This is quite powerful without being out of control. With a carbide bit this thing positively shreds steel, making tedious jobs go quickly. As a result the Air Cat mostly sits in the tool drawer, while I use this for every job.

This die grinder is well worth the money. Good construction and lots of power. A little bulky but not too bad.

I wasn't sure if a whole horsepower was going to make a great difference but once I held this thing I started to believe it would. It's a little on the thick side.Then I used it.Let me paint you a picture, I do a lot of engine swaps at work on cargo tractors and heavy equipment. One common issue I encounter while doing these engine swaps is the factory welds on the frame have cracked almost all the way through or completely separated. This tools primary function is to eat away all the old, crappy welds from the factory and to leave me a nice groove to fill in with the arc welder.I keep a carbide burr in this die grinder and I gotta say, compared to every other die grinder I've borrowed in our shop this thing is an absolute performer. For one, it just sounds powerful but for cutting away welds and grooving frames, this thing EATS the metal. I need to wear more PPE because I'm getting completely showered in metal shavings! I mean it's literally raining metal! This tool will hardly slow down at all no matter how forceful I am.Another incredible tool from Sunex and I'll be sure to buy another should this one ever die!

When I buy a cheap tool from a name I don't know, I assume it's going to be garbage. Happily, this Sunex 1HP die grinder surprised me.I have other die grinders, all .33 or .4 HP from Ingersoll-Rand; in comparison the Sunex is noticeably larger and louder, and way more powerful. With a 1/2" carbide burr digging into steel, I can easily stall the smaller grinders, but the 1HP Sunex is clearly in a different class.I've been using the Sunex every day for the last couple of weeks, if it lasts even for six months it will be excellent value. If it lasts for years, it will be the best deal on a die grinder ever. I think it will last for years, it feels well-built and sturdy. Strongly recommended.
