3M 7100032853 Hookit D/f Disc Pad 6x0.75in 5/16-24

Product Description

The 3M 7100032853 is a Hookit D/F Disc Pad designed to back dual-face abrasive discs during surface preparation and finishing work. Measuring 6 inches in diameter and 0.75 inches in thickness, it features a 5/16-24 external thread mount and a 6-hole pattern that aligns with dust-extraction abrasive discs. The Hookit attachment system uses a hook-and-loop interface, allowing fast disc changes without adhesive. This pad is sold individually and is sized for use on random orbital and dual-action sanders common in auto body, marine, and light industrial applications. Technicians and skilled tradespeople handling surface prep work will find this pad compatible with standard 5/16-24 threaded tools.

This disc pad is suited for use in environments where repeated abrasive disc changes are required, such as auto body shops, marine refinishing, woodworking facilities, and general industrial surface preparation. The 6-hole configuration supports dust-extraction abrasive discs, making it appropriate for situations where debris management is important. It is intended for use with dual-action and random orbital sander bodies accepting a 5/16-24 external thread interface.

Key Features

• 6-inch diameter pad fits standard dual-action and random orbital sander platforms
• 0.75-inch thickness provides consistent backing compliance across the disc face
• 5/16-24 external thread mounting for secure sander attachment
• 6-hole pattern aligns with dust-extraction abrasive discs to support debris removal
• Hookit hook-and-loop interface enables fast, tool-free disc changes

Compatibility

Designed as an OEM-style replacement backing pad for dual-action and random orbital sanders equipped with a 5/16-24 external threaded spindle and compatible with 6-inch hook-and-loop abrasive discs featuring a 6-hole dust-extraction pattern.

Installation Notes

Installation is performed by threading the pad onto the sander spindle by hand until snug — do not use tools to overtighten, as this may damage the threads. Ensure the sander is disconnected from power before replacing or inspecting the backing pad. Verify that the hole pattern on the abrasive disc aligns with the pad holes before use to maintain dust extraction performance. Inspect the hook face of the pad regularly and replace when hooks show significant wear or disc retention becomes unreliable.
