EYPINS Heavy-Duty Pneumatic Right Angle Die Grinder with Dual 1/4" & 1/8" Collets - Includes 22-Pc Kit for Metal Polishing, Grinding, Sanding & Rust Removal

No gear drive/less wearable parts. Great for surface prep!

I have started to find more and more uses for a quick grind on something. I have started to learn to weld, and a tool like this (especially if you already have a compressor) is very handy for grinding spots to weld on, then grinding the welds to make them nice and shiny. Although it’s for smaller quick bursts of grinding, there are occasions when I do a lot of small welds, then need to clean them up etc, but that takes a lot of AIR! I have a huge CAT 20 gallon compressor and it can’t keep up for an extended period of grinding. There is a lot of air throughput required.But it works great. The small diameter grinding heads get into areas that an angle grinder can’t. It fits directly on the standard air quick connectors. There is a speed controller knob for the air flow by the way, but I always run full-ish. Too low and you can stall it. But overall the amount of accessories included as well as the versatility I have found for grinding is awesome.. listen, it comes with wood sanding tools, but this works way better in the metal shop than a wood shop. The sanding pads work, but it’s for a super small area.. otherwise I’m using my random orbital sander, for smaller detailing I use an oscillating tool with sanding attachments.. for this one the Blue aggressive sanding head for metal, perfect. This is the second product I have from Eypins and both are equally great quality. I use this one more and so far so good. Solid tool. 5 stars.

It's a well made right-angle die grinder, and what I like the most about it is the grip. It has a really nice, soft, and comfortable overmold, which is much easier to hold onto for extended grinding/polishing jobs.The switch doesn't have a safety, but I prefer that over the other actuator style. I also like that the set already has the silencer and flow valve attached; it saves a lot of hassle in setting it up. It also comes with a pretty comprehensive set of abrasive pads and arbour, with an extra couple of collet wrenches thrown in.It's a little more expensive than some of the other right-angle die grinders, but I like it because of its overall comfort and the fact that it includes a bunch of abrasives. It's competitive with the other products out there, but it does have just a little bit more comfort in using that makes it worth it. I can easily recommend the grinder.
