The DeWALT Impact Driver features a frameless motor for longer life and replaceable brushes for increased serviceability. The durable magnesium gear case and all metal transmission provide excellent durability. The compact size and weight allow access in tight quarters. The textured, anti-slip comfort grip offers the user better control. The heavy-duty impacting mechanism directs torque to the fastener without kickback. Includes tool only (battery & charger sold separately).
