Review on Chicago Pneumatic CP9105Q B Straight Grinder: Precision and Power Combined by Neil Biondo

Great tool! Powerful, comfortable, easy to use and very quiet (compared to most pneumatic straight grinders). I use it for deburring steel and aluminum and for cleaning and smoothing welds. This is a high quality, durable yet lightweight tool. The handle and speed controller are well designed and convenient to use. I like the 45 degree angle as a good compromise between straight and 90 degree tools when you need one tool for many purposes. Best of all, this tool is very quiet - it doesn't produce the deafening squeaks that many pneumatic tools produce.
