Metabo is known for producing top-quality grinders, and its WP780 4-1/2-inch angle grinder is no exception. At 4.7 pounds it's lighter than competing models, and the slim motor housing and 15-degree offset side handle should make it comfortable to use. The 7.2-amp motor delivers 14 inch-pounds of torque – enough for edge-grinding, deburring, weld-grinding, and tile-cutting. A nonlocking paddle switch enhances user safety by turning the grinder off when its trigger is released or the tool is dropped. ¦ Price: about $100. www.metabo.us.
