Heavy-Duty Structural Features
-
Advanced Motor Armoring: Uses a specialized zig-zag varnish baked onto the armature coil. Because 9″ grinders create massive dust clouds, this rotating varnish creates a physical barrier that deflects flying masonry and metal particles before they can scratch the copper wire.
-
Rotatable Rear Handle: The rear grip housing can be rotated 90 degrees left or right relative to the gear body. This keeps your trigger hand comfortably aligned whether you are cutting vertically down into a wall or grinding horizontally on a table.
-
Torque Transfer: Built with heavy-duty spiral bevel gears. These provide smoother rotation, much lower gear vibration, and a highly efficient transfer of kinetic energy under immense pressure.
-
SJS & Soft Start (On specific “R” or “S” suffixes): High-end variants feature a soft-start motor to prevent a sudden power kick when pulling the trigger, along with a slip-clutch system to protect the user if the 9″ wheel gets bound up in concrete.
