The DWE4206 features a high efficiency motor design which improves performance in demanding applications. The dust ejection system removes the majority of debris from the air which passes over the motor, preventing abrasion and tracking. It has a small girth allowing a comfortable grip resulting in superior ergonomics. The low profile gear case allows access in confined areas and the anti vibration side handle improves user comfort. It also has an anti lock flange to prevent it from permanently locking up with the disc on. The new guard design allows fitment, adjustment or removal without the use of tools, for increased flexibility. The fully leaded stator windings lead to increased motor durability and pop off brushes protect the armature from damage at the end of brush life, resulting in greater motor durability. The motor is abrasion protected for increased durability. The side positioned spindle lock gives greater protection to button when using in confined spaces. A No-volt release switch prevents the unit from starting unintentionally when locked on. The switch must be consciously reset before power is delivered. Soft start reduces movement of the tool on start-up increasing user control.
