SJS™ Mechanical Clutch System Helps Prevent Motor and Gear Damage
- Powerful 10.0 AMP motor delivers more output and 10,500 RPM for the most demanding applications.
- SJS™ technology is a mechanical clutch system that helps prevent motor and gear damage by allowing the drive shaft to slip if the wheel is forced to stop.
- Larger cooling fan and blades pull more air through the motor to help maintain lower operating temperature.
- Large flush-mount paddle switch with integrated lock-off tab for more comfortable operation.
- Labyrinth construction prevents debris from penetrating the motor, bearings and gears for longer tool life.
- “Clam-shell” gear box design for greater durability and easier servicing.
- Spiral bevel gears for smoother rotations and a more efficient transfer of energy.
- Zig-zag varnish protects the armature coil from dust and debris for longer motor life.
