The DEWALT DWE4011 eatures a 7.0 amp AC/DC, 12,000 rpm motor, which was designed for faster material removal and higher overload protection. The One-Touch Guard eliminates the need for a tool to adjust the guard location; No buttons or levers, just turn the guard to position it. This unit has a hex wrench which replaces the spanner wrench (a hex wrench is found in most tool boxes if lost). It has a low profile, jam-pot gear case which increases durability and allows tool to fit into tight spaces. It also features a quick-change wheel release that allows for tool-free wheel removal without need for a wrench. As an added bonus, the two-position removable side handle provides increased comfort and control. To make this tool more versatile, the 5/8-inch-to-11-inch spindle thread accepts a wide range of 4-1/2-inch accessories. You will enjoy working with this slim, ergonomic body design as it provides increased comfort in extended use applications.
