3M 7100255168 Scotch-brite Hookit Finish Disc Very Fine 3 in

Product Description

The 3M 7100255168 is a Scotch-Brite Hookit Production Clean and Finish Disc engineered for fine finishing, paint prepping, scratch blending, and surface conditioning across a wide range of substrates. Built on a non-woven, open-web nylon structure with aluminum oxide abrasive incorporated directly into the fibers, the disc delivers a consistent cut rate and finish quality throughout its full service life. Rated Very Fine in grit grade, it operates at a 3-inch diameter and attaches via a hook-and-loop interface to a compatible backup pad on a random orbital sander. Load and heat resistance keeps the abrasive cutting cleanly without glazing or undercutting the base material.

This disc is suited for conditioning aluminum, stainless steel, plastics, wood, and fiberglass in both metalworking and woodworking environments. It conforms well to irregular and contoured surfaces, making it effective for scuffing primer, blending scratches, and prepping painted panels before recoat. The Hookit attachment system supports fast disc changeover during multi-step finishing operations, reducing downtime in production and refinishing workflows. Applications range from light industrial fabrication to automotive body work and composite surface prep.

Key Features

• Aluminum oxide abrasive self-fractures during use to continuously expose fresh cutting edges, extending disc life
• Non-woven 3D open-web structure resists loading and clogging for consistent abrasive action
• Hook-and-loop Hookit attachment allows fast, clean disc removal and reattachment without adhesive contamination risk
• Conforms to irregular and contoured surfaces without undercutting or damaging the substrate
• Effective on aluminum, stainless steel, plastics, wood, fiberglass, and ferrous alloys
• Very Fine grade delivers controlled material removal for finish blending, scuffing, and paint prep

Compatibility

Designed for use with hook-and-loop backup disc pads on random orbital sanders; backup pad sold separately. Compatible with standard 3-inch hook-and-loop disc pad systems.

Installation Notes

Install the disc onto a clean, dry hook-and-loop backup pad, ensuring full seating before tool operation. Confirm the backup pad and sander spindle are rated for the disc diameter in use before starting. Inspect the disc before each use and discard if the abrasive surface shows heavy loading or fiber breakdown. Follow applicable shop safety practices including eye protection and dust collection when working with abrasive finishing discs.
