Review on Chicago Pneumatic CP875 4 Inch Grinder by Scott Ward

This is my second one. The last one had tens of thousands of hours. I like the small size for getting into tight spaces in bowls and impellers. I work with dudes who work with dotcos and other $500 tools and I rate these things by the amount of vibration. I expect and demand that whatever I bring into the store for a living gets used to it. If you work for hours manually with one of these pneumatic tools, the smoothness during operation determines the level of hand fatigue. These from this manufacturer for the money are the smoothest I've found.
