Disc Pad Hub for Sanders
The 3M 88743 is a fibre disc pad hub designed for use with Sanders. It features a threaded hole connector sized at 5/8 In. -11 for secure attachment to compatible power tools. The hub measures 2.5 in overall diameter and comes in a pack of 10.
Suited for Quick Disc Changes
This hub suits operators who need a reliable mounting point for fibre discs on Sanders with a 5/8 In. -11 spindle. It is not intended for tools requiring a different connector size or a quick-change mounting system. Buyers needing vacuum-hole configurations or alternative backup pad shapes should look elsewhere.
Critical Specification: Connector Size
The decisive specification is the 5/8 In. -11 threaded hole connector. Verify that your Sander matches this exact thread before purchase, as an incorrect fit will prevent the hub from mounting safely.
