Design

The rear handle’s design gives the user more control and comfort. External brush caps for easy roller bearings and the sealed ball can extend the motor’s service life.

Protection against dust and debris

Sanding is a messy process, but DeWalt has done an excellent job keeping dust to a minimum. The motors must continue to be ventilated. This is accomplished by a few valves located near the tool’s back end. The mesh appears to be appropriate for the micrometer size associated with metal and concrete grinding, and it adheres to the tool washer rather than being part of the mold. This, I believe, allows for some network cleaning. If so, DeWalt did an excellent job with the design.
