... An EXCELLENT little tool .... to be used carefully .... very lightweight ... particularly good for very light/delicate polishing and or modelling work ... very well made ... but be careful its not abused ... I use it for work that the 'Dremel' is too brutal for ... I am VERY happy with it.

all good

If you are in the market for a decent little pneumatic die grinder, I think you will like this one. It's affordable, and does what it's supposed to do. I've put about 20 hours on mine, and it's still going strong. Make sure to lubricate liberally and often, as you should with many pneumatic tools. It will heat up fast if not lubricated, but operates quite well otherwise.

I normally do not take the time to review a product since there are many reviews already but this item is worth a review. I restore carburetors for Porsche cars and after machining operations are completed on the aluminum bodies I soften the sharp edges by hand using manual deburring tools, scrapers and files. This is rather tedious and it is also a bit hard on the hands and elbows. I thought that trying this pencil sized die grinder would be worth the price and in spite of some of the negative reviews I bought one. Short story: Works like a champ! Smooth running and seems to be well made. I use a flow control valve to adjust total air flow to the tool to slow it down a little and with a carbide bit installed it makes my deburring job a lot easier! I do wear ear protection since it does make a high pitched racket which I happily accept for the improvement in my work. I do not have a comment regarding longevity or how robust the grinder is. It does run smoothly and there are no run-out issues like other users have reported.

The product itself is amazing, works great, good quality and has power to it. But when it arrived. It wasn’t packaged in anything. Was on my door step in its box that says what it is with the picture. Just had the shipping label on it. That is upsetting to me because someone walking by could of easily saw what it was and stole it.
