3M 7000118716 Woodruff Key Orbital Sander

Product Description

The 3M 7000118716 is a Woodruff key used to connect the rotor to the shaft balancer in orbital and random orbital sanders. This small but critical drive component maintains the rotational alignment between the rotor and shaft, preventing slippage during sanding operations. Without a properly seated Woodruff key, the rotor cannot transfer torque reliably to the pad assembly. Replacement is typically performed by tool repair technicians or experienced users during sander rebuild or maintenance procedures when wear or damage is identified on the existing key.

This Woodruff key is designed for use across the 3M line of orbital sanders and random orbital sanders. It applies to both professional-grade and production sanding tools where the rotor-to-shaft connection is secured by this style of key. The part is sold individually, making it suitable for single-unit repair without purchasing a full hardware kit.

Key Features

• Connects rotor to shaft balancer for reliable torque transfer
• Compatible across orbital and random orbital sander platforms
• Sold as individual unit for targeted repair use
• OEM replacement part maintaining original fit and function

Compatibility

Designed as an OEM-style replacement for use on all 3M Orbital Sanders and Random Orbital Sanders per manufacturer application data.

Installation Notes

Installation and removal of internal sander drive components should be performed by a qualified tool repair technician. Disconnect the tool from the air supply or electrical source before disassembly. Use appropriate snap ring pliers, shaft pullers, and non-marring mallets as needed for housing removal. Refer to the applicable 3M service documentation for disassembly sequence before proceeding.
