SUNTECH SM-52-5300 Sunmatch 1/4" 90 Degree Angle Pneumatic Die Grinders, 0.3HP, 20,000Rpm, Black

No vibes, really smooth. Like everything about it, especially the price.

This unit outperforms my old Matco, Snap-On and pretty much every other one I've owned. Quiet, plenty of power and seems to use the air more efficiently.

Just as good as matco or snap on. Just have to put a small regulator to dial it down for cookie wheels so they don't fly off.

Very comfortable to use. Nice size very durable. If you need one for use as a palm sander I recommendOne with a little lower Rpm cuz this one is a little high palm sanding disks with 14-18k maximums have trouble on it. But as far as 90° grinders goes tremendous value for money

So I purchased this to use to clean brake caliper brackets on the daily as I am an automotive technician. Screw Snap-On, these guys made an equivalent quality tool for half the price and it's basically dead quiet compared to cheap ones of these. It also has a considerable bit more power than the cheap ones as well, overall it's amazing and I could not recommend it more.

For the money this is the smoothest operating die grinder I have used. Be careful, there are counterfeit SUNTECH tools out there, you can tell by the different logo style and usually they have a much cheaper price.Very happy with this tool, it is made well and has a greasable head.

We'll so far so good it still working and performs well,the trigger mechanism is a bit cumbersome and hard to use but doesn't impact the performance,for the price it's a good tool.

Very weak. Only suitable for a 2 inch roloc at best. If you do heavy grinding for extended periods I’d recommend paying just a little more for a .5hp unit.

I have used this die grinder for the last 3 years and i am impressed by it’s longevity. I use this tool for metal preparation before , during and after flux-core welding. (Lots of residual slag to be removed). I like to use it with either wirewheel or roloc discs. It is really quiet with minimal vibrations. I don’t use this tool daily, maybe monthly. It’s quieter then my straight shaft DeWalt air die grinder and easier to clean. It does see some automotive work with brake and suspension work.This die grinder is made in Taiwan. I am impressed with the Taiwan craftmanship, better then many Chi..se cheap copy of quality tools in my personnal experience.

I needed a quiet one, and discovered they are not so common. This budget price grinder really is quiet and works well. Would recommend.

Unfortunately I just threw this mess of parts in the garbage yesterday. Wouldn't rotate, 3rd time using it, less than 10 minutes run time. Save your cash and buy one with a better reputation.

ok for the price
