    • 3 years business use and still going strong. Detailed long term review.
Size: Metal Housing Style: 301B - Air Angle Die Grinder
Short version: I bought two of these in Feb 2018 for use at my business. They're still going strong and work great. Long version: The HF cheapie die grinders are fine for the guy at home using them once in a blue moon, but they don't hold up at all for regular use. I wanted to get something better than the HF junk but was not willing to spend hundreds for a true "industrial" model. These have fit the bill perfectly. Both units are primarily used with roloc pads doing general metalwork. One has a 3" roloc and is primarily rough sanding. The other has a 2" roloc with some sanding but is primarily used for deburring and polishing with scotchbrite pads. For how we use them power is never an issue but speed modulation is very important. These have been great for that. Interestingly, the more expensive IR models I considered have multiple reviews complaining about a lack of speed control, but I've had no complaints with this model. The front exhaust has been a plus for our use. But, I do not have auto-oilers on our shop lines. We just manually add a few drops once in a while (probably far less frequently than we should). They are not used all day every day like a production fab shop, but they definitely see daily use. Honestly though, if you're using a tool for multiple hours every day you should be buying WAY more expensive industrial level air tools. As others have mentioned, the collets do have a tendency to stick. This hasn't really been an issue for us. We're not changing things that often and when we do they break loose with a tap after loosening the nut sufficiently. In summary, at this price point I can't imagine a better bang for the buck. They're good quality yet still very affordable. Speed modulation is great. They are compact and light weight. They have a study, solid feel to them, not loose and sloppy like the HF tools. I will definitely buy these again if we need more. ... show more

Size: Metal Housing Style: Straight
Awesome size, awesome performance - only taking off one star because I had to take off the bottom hex fitting and put some sealant tape and thread locker on it and put it back together, cuz it leaked rather badly out of the box. No biggy really, but putting it in a vice with some rags to get the stupid fitting off was more of a pita than it really should have been, since the flat spot on the handle isn't really sufficient to do that with. Also, the speed adjustment doesn't make much sense. The screw either has it at high or low, there's no in between, and I'm not even sure at this point how far in or out the screw actually is, it doesn't really stop in either direction. Not very straight forward at all. To be fair, the high and low settings are pretty much what you would need, but I wish this could go a LITTLE slower, like 20% slower at the slowest setting. Still holds up to the ones my friends have that they paid double/triple for, so it's a great bargain, probably the best you will find on an air die grinder. Awesome for porting heads with. Can't comment on air requirements, I have a giant 60g air compressor pumping 90psi into it with no problems. After ~2 minutes straight of grinding at full, the compressor will kick on for like a minute and fill back up, whatever that tells ya. ... show more

    • IR Die Grinder
Size: Metal Housing Style: 301B - Air Angle Die Grinder
I've only used this once so far. I still oil it and fire it up on the air line from time to time to make sure its working. I started replacing my older air tools with IR air tools and so far they work great. I have both this angle grinder and the straight grinder for whatever may come down the road (better safe than sorry). I also have a few of their air ratchets as I do my own automotive work. For the price you can't really beat it. I mostly work on my own vehicles so these don't see the normal abuse as they would in a shop environment but they are still holding up after at least 6-7 years of ownership. ... show more
