  • 3 years business use and still going strong. Detailed long term review.
Size: Metal Housing Style: Right Angle
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

  • BUY BUY BUY
Size: Metal Housing Style: Right Angle
I was pleasantly surprised with the quality of the tool. The construction of this grinder is phenomenal, but i have some gripes. Philosophy of Use - the GO TO metal prep tool. 1. Initial quality - very impressive. The tool has a very nice finish and comes in a sturdy box with manual, tools, and extra collet. It is reminiscent of some $400.00+ tools that i have purchased in the past. The finish is so good that i thought a more expensive model was sent by mistake. 2. Operation - very impressive. The tool sips on air and does not drain my 15 gallon tank too fast. High speed operation with zip disks is great. Rust flew off the metal during initial testing. Additional drawback is that you have to store the wrenches somewhere and not lose the. The space between the tool body and collet nut is narrow and I am not sure if a standard wrench will fit to tighten or loosen the nut. 3. Ergonomics - adequate. The tool is too small for my hands. I was unable to get a good grip on it to keep up with the torque on uneven surfaces. I was not wearing gloves. (ALWAYS WEAR GLOVES) so this may change with gloves. This small size could be a plus though it you are working in tight spaces. 4. Durability - unknown. i will update but based on build quality i bet it will last a lifetime. 5. Overall Customer Satisfaction - Impressive! I recommend you buy this! This tool is so nice i wanted to cuddle with it at night. ... show more

  • IR Die Grinder
Size: Metal Housing Style: Right Angle
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
