3M 7000035846 Non-woven Surface Conditioning Disc 0.75 in

Product Description

The 3M 7000035846 is a non-woven surface conditioning disc designed for deburring, cleaning, finishing, and blending on metal and contoured workpieces. Built on an open-web fiber construction with an aluminum oxide abrasive at medium grit, it removes burrs and surface oxides while running cool enough to prevent heat discoloration on sensitive materials. The Roloc quick-change backing locks into compatible right-angle die grinders without tools, reducing changeover time during multi-step finishing sequences. At 0.75 inches in diameter, it reaches tight geometries and irregular profiles that flat rigid abrasives cannot follow. Technicians in fabrication, HVAC service, plumbing rough-in, and electrical panel work reach for this disc when prep quality matters on confined or contoured surfaces.

This disc is suited for light-duty surface prep tasks where conformability is critical. Typical applications include deburring pipe ends, blending weld seams in tight access areas, removing mill scale or light corrosion, and scuffing surfaces before bonding or coating. The small diameter makes it a practical choice for work inside enclosures, around fittings, and along structural members where a larger disc cannot safely operate. It is intended for use with Roloc-compatible pneumatic or electric die grinders operating at appropriate RPM ratings for this disc size.

Key Features

• Non-woven fiber construction conforms to irregular and contoured surfaces without gouging base material
• Open-web design resists loading and dissipates heat for consistent cut rate across the disc life
• Aluminum oxide abrasive at medium grit provides aggressive deburring with controlled surface finish
• Roloc quick-change attachment allows tool-free disc swaps during multi-step finishing workflows
• 0.75 inch diameter accesses confined spaces and tight geometries standard discs cannot reach

Compatibility

Designed for use with Roloc-compatible die grinders and rotary tools that accept the quick-change twist-lock attachment system. Verify maximum RPM rating of the host tool is appropriate for this disc diameter before use.

Installation Notes

This disc is installed and serviced by trades professionals performing metal fabrication, pipe prep, or surface finishing work. De-energize or depressurize any system before grinding or deburring components in place. Seat the Roloc backing fully into the mandrel and confirm the locking engagement before running the tool. Always wear appropriate eye and face protection and confirm the tool speed does not exceed the disc speed rating.
