Customer Reviews

11 Amp 4.5 in. Small Angle Grinder with Trigger Grip is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Dissappointed I've been buying Milwaukee tools for at least 30 years and have always loved their quality. However, I recently bought this grinder and found it to feel loose, wobbly. Overall it feels like a cheap tool. The worst part is that it is made in China. Imagine that. Milwaukee tools made in China. Thats a shame.
