3M 7100086107 Hook Loop Abrasive Disc 8 in Very Fine

Product Description

The 3M 7100086107 is a non-woven hook and loop abrasive disc designed for surface finishing, blending, and light material removal. Built on an aluminum oxide abrasive material with a very fine grade, this disc delivers consistent scratch patterns suitable for final finishing stages on metal, wood, and painted surfaces. The flexible non-woven construction conforms to contoured workpieces, reducing the risk of gouging or uneven material removal. At 8 inches in diameter and rated to 6,000 RPM, it fits standard random orbital and disc sanders equipped with hook and loop backing pads. Part of the SC-DH series, it is used by metalworkers, fabricators, and finishing trades.

This disc is suited for industrial and trade finishing applications where consistent, fine surface preparation is required. It performs well on deburring, surface conditioning, and pre-paint prep on ferrous and non-ferrous metals, as well as wood and composite materials. The blue non-woven substrate provides visual wear indication and maintains flexibility across irregular surfaces. Vacuum holes are not included, making it appropriate for use on sanders without dust extraction ports. It is sold individually and is compatible with any 8-inch hook and loop backing pad.

Key Features

• Aluminum oxide abrasive material for reliable cutting action on metal and wood surfaces
• Very fine grade for final finishing, blending, and pre-paint surface prep
• Flexible non-woven construction conforms to contoured and irregular workpieces
• Hook and loop attachment for fast disc changes on compatible sanders
• Rated to 6,000 RPM for safe use on standard random orbital disc sanders
• No vacuum holes — suited for non-dust-extraction backing pads

Compatibility

Designed for use with 8-inch hook and loop backing pads on random orbital and disc sanders. No vacuum hole pattern; not compatible with dust-extraction sanding pads that require hole alignment.

Installation Notes

Install by pressing the hook and loop disc firmly onto a clean, dry 8-inch hook and loop backing pad before starting the sander. Confirm the sander spindle speed does not exceed 6,000 RPM before operation. Inspect the disc for wear, loading, or delamination before each use and replace if the abrasive surface is spent or the backing shows separation. A licensed or experienced trade professional should follow applicable shop safety standards, including eye and respiratory protection when dry sanding.
