The unit is only 1.7 lb (760 g) and 3.26 in. (83 mm) high to reduce wrist fatigue and provide exceptional fingertip control. There are two interchangeable grips provided to suit operator hand size. A lock-off lever prevents accidental starts. Noise level through the rotatable silencer is only 76 dB(A) for non-vacuum sanders. The vibration levels are lower than 2.5 m/s².

The lubrication-free pneumatic motor generates 0.3 hp with a variable speed range from 0 to 12,000 rpm for highly productive finish sanding. Oversized, dual ball bearing sets are double-sealed for long life.

Available pad diameters include 3.5 in. (89 mm), 5 in. (127 mm) and 6 in. (150 mm). Each size is available in three dust extraction versions: non-vacuum, self-generated venturi vacuurn and external vacuum system. All models share common parts and components for reduced spares inventory.
