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.
