The DeWalt DWE4517 is a large 7-inch angle grinder built for heavy stock removal and cutting on concrete, steel and masonry. Its 4 HP max motor spins at 8,500 rpm and holds speed under load through overload protection, which puts it in the same class as other big corded grinders from Makita and Bosch. The low-profile gearcase and two-position side handle help in tight spots, and auto shut-off brushes protect the motor. It suits tradespeople doing sustained grinding and cutting rather than light home jobs.

Owners of DeWalt's large grinders generally rate the power and durability highly, and the brush shut-off is a common point of praise. Complaints tend to focus on weight and vibration during long sessions.
The DeWalt DWE4517 is a 7" angle grinder with a 4 HP (maximum motor HP) motor that runs at 8,500 rpm. Overload protection helps it keep a higher operating speed under load. The 8,500 rpm speed is suited to material removal with 9" grinding wheels.
The field and armature have an epoxy coating that protects them from abrasion by airborne debris. A low profile gearcase lets it work in tight areas. Automatic turn-off brushes shut the tool down when the brushes need changing, which avoids tool damage.
The side handle can be set in 2 positions to improve ergonomics for specific applications.
