3M 7100028484 Hookit Low Profile Finishing Disc Pad 5 in

Product Description

The 3M 7100028484 is a low profile finishing disc pad designed for use with 5 inch Hookit D/F abrasive discs featuring the Die 500FH five-hole dust extraction pattern. Built with soft foam construction, this pad is engineered for fine finishing work where surface quality matters. The one-piece threaded shank design reduces vibration and improves rotational balance during operation, which directly affects finish consistency. Intended for applications using grade 220 abrasives or finer, this pad is a purpose-built tool for final surface prep stages. It is installed and used by body shop technicians, automotive refinish professionals, and finishing trade workers who rely on controlled material removal at fine grits.

This disc pad fits into fine-grit finishing workflows where low-profile pad geometry helps maintain flat, consistent contact with the work surface. It is suited for use on body panels, composite surfaces, and other substrates where a smooth, defect-free finish is the end goal. The 5/16-24 external thread interface is a standard connection used across a wide range of orbital and random orbital sanders. Use with coarse grade abrasives is not recommended, as coarser grit loads generate heat and mechanical stress that can cause premature foam breakdown.

Key Features

• Soft foam construction optimized for fine-grade abrasive applications (grade 220 and finer)
• One-piece threaded shank reduces vibration and improves pad balance during use
• Low profile design promotes flat, even disc contact on finished surfaces
• Compatible with 5 inch Hookit D/F discs using the Die 500FH five dust hole pattern
• 5/16-24 external thread fits standard orbital sander spindles

Compatibility

Designed for use with 5 inch Hookit D/F abrasive discs featuring the Die 500FH five dust hole configuration. Not recommended for use with coarse grade abrasives due to risk of premature foam failure.

Installation Notes

Thread the pad onto the sander spindle by hand until snug using the 5/16-24 external thread interface. Ensure the sander is powered off and disconnected from any air or electrical supply before installing or removing the pad. Inspect the foam face for wear or deformation before each use, as a damaged pad face will affect disc adhesion and finish quality. Do not exceed the abrasive grade range specified for this pad.
