3M 7000046094 Disc Holder Adapter 5/8-11 M10-1.25

Product Description

The 3M 7000046094 is a thread adapter designed to convert a sander with an M10-1.25 external threaded shaft to a 5/8-11 external threaded shaft. This allows technicians and tradespeople to use 5/8-11 disc holders on tools that would otherwise be incompatible due to differing spindle thread standards. The adapter is a compact, single-piece component weighing 0.08 pounds, making it a lightweight addition to any tool kit. It is typically installed by grinding and surface preparation professionals, auto body technicians, fabricators, and maintenance trades who rely on disc-type abrasive tools across a variety of material removal and finishing applications.

This adapter suits applications where a sander or grinder with an M10-1.25 threaded spindle must accept 5/8-11 disc holder accessories. Common scenarios include automotive bodywork, metal fabrication, industrial maintenance, and surface prep tasks. It bridges a widely encountered thread standard mismatch between metric-spindle tools and inch-thread abrasive accessories, expanding the usable accessory range of compatible sanders without requiring a separate tool.

Key Features

• Converts M10-1.25 external threaded spindle to 5/8-11 external thread output
• Enables use of 5/8-11 disc holders on metric-threaded sanders
• Lightweight design at 0.08 pounds — minimal added mass to the tool assembly

Compatibility

Designed for use with sanders featuring an M10-1.25 external threaded shaft. Compatible with 5/8-11 disc holders when installed. Refer to tool and disc holder documentation to confirm thread engagement and safe load ratings before use.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive tool assembly. Disconnect and de-energize the sander completely before attaching or removing any spindle accessories. Thread the adapter securely onto the M10-1.25 spindle before mounting the 5/8-11 disc holder, and verify that all connections are fully seated and snug prior to operation. Follow applicable ANSI abrasive wheel safety standards and the tool manufacturer guidelines for maximum spindle speed and accessory ratings.
