Maintenance-free

Conventional commutator motor

No more troubles with armature burnout,layer short or commutator wear.

Significantly extended product life cycle

No carbon brushreplacement required

provides high vibration-absorbing effect by employing both transatory and hinge units.

Reduced vibration and improved operating efficiency

The internal double-insulation construction with a very sturdy aluminium die-cast body and a plastic internal stator holdermakes the housing more rigid, significantly enhancing durability of the motor unit.

Alminiumdie-cast

Plastic

reduces the vibration from concrete drilling or chiseling by moving a weight and a leaf spring in the opposite direction to the movement of the hammer.
