The JET Tools MG3HDE SUW-402121 is a pneumatic die grinder intended for heavy duty industrial work. Its .6 HP motor sits in a compact housing with front-directed exhaust, while a 3" shaft provides the extended configuration. A vibration-absorbing coupling nut joins the shaft and motor and allows disassembly for repairs. The shaft has a polished chrome finish, and an insulating vinyl cover supports operator comfort and safety. A roller-tipped throttle lever controls operation, while an inlet screen helps keep air-line debris out of the motor.

• Motor construction: ball bearings support both ends of the motor shaft; die-cast aluminum end plates provide durability. The coupler contains an additional ball bearing.
• Extended shaft: solid bar stock construction with three precision ball bearings and an internally machined, polished housing designed to limit run-out and support smooth, accurate operation.
