This Dewalt DWE4011 grinder has a powerful motor designed for faster material removal and higher overload protection. It is equipped with One-Touch(TM) Guard, which eliminates the need for a tool to adjust the guard location - no buttons or levers, just turn the guard to position it. A low profile, jam-pot gear case increases durability and allows tool to fit into tight spaces. The Quick-Change(TM) wheel release allows tool free wheel removal without the need for a wrench, and the 2-position removable side handle provides great comfort and control. Three-year limited warranty.
