Features:
- Improved Dynamic Torque (1.2 times torque of our previous model is generated at 300 r/min, on model : KH42JM2-901)
- Lowered Vibration & Noise Level (by increased stiffness of body construction)
- Improved Efficiency (1.1 times of our previous model, by high grade materials.)
- Strong torque and quieter running by a unique tooth profile.
- Extended applicable range by standardized specification & higher speed.
