Overview

Grinding, deburring and shaping small work is the job of this DeWalt cordless die grinder. The listing includes a one quarter inch collet and wrench, and describes it as compact with variable speed control.

The reason to buy is a cordless grinder with speed control and a very high top spin for fine work, plus a warranty package with service and money back terms. The limit is that it is a bare tool, so battery and charger are extra.

Who it's for

Detail grinding, port work and deburring in tight spots away from an outlet is the setting. If you only have a different battery platform, the tool will not run on it, so check compatibility first.

Pros and cons

Pros
  • Variable speed control
  • Collet and wrench included
  • Warranty with service and money back terms
Cons
  • Tool only, battery sold separately
  • Compatible battery models not named
  • Only one collet size listed

Performance notes

Variable speed lets you drop the spin rate for control on delicate work and raise it for faster material removal. The collet grips the bit shank, so the shank size sets what bits you can use. Run time per charge depends on the battery pack paired with it.
