If you are in need of a heavy-duty product that can handle a variety of tasks, then you may be interested in a grinder.

This adds protection in case of an accident or drop.  Along with this, the Dewalt DCG413B comes with a One-Touch Guard. This enables you to adjust the guard position quickly and in a single movement. This product also features a spindle lock for your added convenience.

This grinder features an anti-wobble hitch pin, as well as a two-stage trigger. The two-stage trigger is much faster, and only takes two movements to start the tool up. On top of this, the Dewalt DCG413B also comes with an adjustable handle position, to make working with the product much easier. This product is a paddle grinder type, for your convenience.

The Dewalt DCG413B is ideal for heavier-duty tasks such as concrete, brick, and paver cutting jobs. This grinder takes a 20-volt battery, but does not come with one included. A battery and charger need to be purchased separately for use.
