Chicago Pneumatic CP860 - Air Die Grinder Tool, Welder, Woodworking, Automotive Car Detailing, Stainless Steel Polisher, Heavy Duty, Straight, 1/4 Inch (6 mm), 0.54 HP / 400 W - 24000 RPM

Fast shipping, probably one of the most powerful for the price. Lot of torque and can take a lot of loads. I barely used it on the disc to remove the rust and as you can see on the pic, it did way more than a good job. It came with 2 small wrenchs to easily switch whatever you need to use.

I brought a few other grinder, sure cheaper then this one, before but after a little time of use they all literally fall apart in my hand. I got frustrated and chose this more expensive one, thinking it will probably pay for it self in the long run. I have this grinder for about a month now, using it almost everyday and I'm very happy with it. You can tell as soon as you see this grinder the first time, it ain't that cheaply made what you can get for like twenty dollar. I'm sure it will be a great tool for a while, after all if you use these kind of tools, you know they don't last forever. But I'm expecting to use this one for a couple of years at least. I would recommend this tool to anyone who is looking for a reliable, well built grinder for a regular usage. (Just as a note, if you just have a one time job, any cheap one will be fine for that. )

I have a few of these in my shop and they are worth the money. You'll notice right away that they don't rotate in your hand and are actually pretty comfortable to use despite the fact that they look too square to be comfortable. What you won't notice right away is that they will last much longer than a lot of other die grinders and keep their power instead of having reduced power over time and increased vibration from worn parts. I have one that is probably about 6 years old and have thrown away several newer die grinders from other manufactures as their inards wear out, but my CP860 is still going strong with plenty of power to get the job done.

This is my 4th one of this exact model. I broke my first 2 just due to heavy use. Last one I had for at least 10 years and it got run over. These grinders are fantastic. Came with chuck keys for changing bits and parts breakdown manual which I've never needed.

Works great, has good power output. Good quality, made in Japan.
