The DEWALT 1010W Angle Grinder is perfect for heavy duty cutting applications, its highly efficient motor delivers performance in the most demanding situations. Innovative features like the No-volt release switch, which prevents the unit from starting unintentionally when locked on. The switch must be consciously reset before power is delivered. The soft start reduces movement upon startup of the tool increasing user control. The new guard design allows adjustment or removal without the use of tools, for increased flexibility. The dust ejection system removes majority of debris from the air which passes over the motor, preventing abrasion and tracking. Anti-lock flange prevents flanges from permanently locking up. The brushes are replaceable with fully leaded stator windings and abrasion protection for increased motor durability.
