1. Easy to operate.
2. Continuous duty rating unlike tools with universal motors.
3. Available for operation in single phase and three phase power supplies.
4. Sturdy construction and dynamically balanced pressure die cast rotor.
5. Wide range of power output and speeds to suit every application and grinding media.
6. Optimum cutting speed under varying load conditions due to constant speed characteristics.
7. Less than 5% rpm drop from no load to full load unlike 40% or more in universal motor tools and pneumatic tools.
8. High productivity due to continuous rating, constant speed operation, minimum operator fatigue and down time.
9. Low maintenance cost due to absence of frequent armature burn out or carbon brush Cleaning/replacement problems.
10. Complete freedom of operation, minimum operator fatigue and easy accessibility to remote and restricted areas of job due to the separation of tool from drive machine.
