3M 7010366393 Surface Conditioning Disc 3 Inch 18000 Rpm

Product Description

The 3M 7010366393 is a non-woven surface conditioning disc designed for deburring, cleaning, blending, and finishing metal and contoured surfaces. Built on an open-web fiber construction, the disc conforms to irregular profiles without removing base material aggressively. It mounts via a Roloc quick-change attachment, allowing fast disc swaps during multi-step finishing operations. The 3-inch diameter and 18000 RPM rating make it compatible with standard right-angle die grinders and finishing tools used in fabrication, maintenance, and repair environments. Licensed HVAC techs, welders, pipefitters, and general maintenance technicians reach for this disc when they need consistent surface prep without loading or glazing.

This disc is suited for light-to-moderate surface conditioning tasks on metal components, welds, and fabricated parts. The open-web aluminum oxide construction resists clogging and runs cooler than bonded abrasives, which helps maintain a consistent finish across multiple passes. It is commonly used in shop fabrication, field repair, and equipment refurbishment where contoured or irregular surfaces require a conformable abrasive rather than a rigid grinding wheel.

Key Features

• Non-woven fiber construction conforms to irregular and contoured surfaces
• Open-web design resists loading and reduces heat buildup during extended use
• Roloc quick-change backing system allows rapid disc changes between finishing steps
• Aluminum oxide abrasive provides aggressive deburring and consistent surface blending
• Rated to 18000 RPM for use with standard right-angle die grinders and finishing tools

Compatibility

Designed for use with Roloc-compatible right-angle die grinders and finishing tools that accept 3-inch quick-change discs. Verify tool RPM rating meets or exceeds 18000 RPM before mounting.

Installation Notes

Installation and disc changes should be performed with the tool unplugged or the air supply disconnected. Thread the Roloc stem into the tool mandrel finger-tight until seated. Inspect the disc for tears or damage before each use and do not exceed the rated 18000 RPM. Abrasive disc handling and grinding operations may require respiratory protection and eye protection per applicable OSHA and shop safety guidelines.
