    • Wish I bought this years ago
Material Type: Composite and Aluminum Size: Right Angle
I have never used a small angle grinder and never a pneumatic tool, but this tool is great. I tried it with some Kutzall carbide burrs to help me shape wood, and this tool does an amazing job. I really like the variable speed, which gives me precise control. I may be the only person who likes/needs a slower speed, but it is great. My one comment for improving the design would be to make the Underside of the trigger different. I found that I could put my finger under the trigger to help me keep the tool at a slower speed but it was a bit uncomfortable after a while. This tool has changed the way I work and opened up avenues of creativity for me. Oh, almost forgot.......you can't really see the guts of this tool, but it seems to be very well made and I hope it gives me some very serious service. ... show more

    • Powerful, looks great, quiet, and very ergonomic.
Material Type: Composite and Aluminum Size: Right Angle
I decided to [upgrade] my toolset and change from the CP brand provided by our company. I must admit, I have found this product to be every bit as powerful & rugged as CP, if not, even-more-so. The product looks great and the black coated finish helps me easily identify mine from the other solid aluminum (CP) grinders. I have only had this product a short time (1-week), but all the signs of a well designed, built, and manufactured product are consistent with this item. Pros: • great value • great HP • ergonomic Cons: • haven’t owned it long enough to make an honest durability rating. Giving it 4-stars for that reason alone on durability. ... show more

    • Great tool
Material Type: Composite and Aluminum Size: 7" Extension
Heavier than a Snap-On or Aircat, but it's under $40 and those are the only differences. Great tool. And the speed adjustment actually works. Been using is as a diesel mechanic for the laast few month and it's put up very well with the abuse soo far. No problems.
