3M 7100064862 Surface Conditioning Disc 4 Inch Non-woven

Product Description

The 3M 7100064862 is a non-woven surface conditioning disc designed for deburring, blending, cleaning, and finishing metal and contoured surfaces. Built on an open-web fiber construction, the disc conforms to irregular surface profiles without gouging or removing base material. The Roloc quick-change attachment system allows fast disc swaps during multi-step finishing work, reducing downtime between passes. At 4 inches in diameter with a Very Fine aluminum oxide abrasive grade, this disc is suited for light material removal and fine surface prep on fabricated metal components.

This disc is used in metal fabrication, welding shops, and maintenance environments where surface blending and deburring are routine tasks. The conformable non-woven construction makes it well suited for curved, irregular, or contoured workpieces where rigid abrasive discs would leave uneven finishes. It is installed on right-angle grinders or die grinders equipped with a Roloc-compatible mandrel. Typical applications include weld blending, light rust removal, and pre-finishing prep on steel, stainless, and aluminum.

Key Features

• Non-woven fiber construction conforms to contoured and irregular surfaces
• Open-web design resists loading and dissipates heat for consistent, cool cutting
• Very Fine aluminum oxide abrasive grade suits finish blending and light deburring
• Roloc quick-change backing enables fast disc replacement during multi-step processes
• 4-inch diameter fits standard right-angle and die grinder Roloc mandrels

Compatibility

Designed for use with Roloc-compatible quick-change mandrels on right-angle grinders and die grinders accepting 4-inch non-woven surface conditioning discs.

Installation Notes

Installation is performed by pressing the disc firmly onto a Roloc-compatible mandrel until the attachment engages. Confirm the grinder is powered off and disconnected from the power source before mounting or removing the disc. Do not exceed the maximum RPM rating of the tool or mandrel. Follow applicable workplace safety standards and wear appropriate eye and face protection during grinding and finishing operations.
