The DW887 die grinder provides the flexibility users expect from a high-speed 1/2-inch die grinder with 1/8-inch and 1/4-inch collets. The exclusive safety switch allows users to set the tool down without worrying about it accidentally turning on. This unit works well with carbide burrs, sanding and lap wheels, cut-off wheels, and mounted points. The DW887 is a great compliment to a 4-1/2-inch right-angle grinder for all metal fabrication and pipe work applications.
