3M 7000035850 Scotch-brite Roloc Disc 3/4 Inch Coarse

Product Description

The 3M 7000035850 is a Scotch-Brite Roloc surface conditioning disc designed for cleaning, finishing, blending, and deburring metal and other surfaces. Built on a non-woven fiber construction, the disc conforms to irregular and contoured workpiece profiles without removing base material aggressively. The Roloc quick-change backing system locks into compatible right-angle die grinders and finishing tools, allowing fast disc swaps between steps. The aluminum oxide abrasive mineral is rated coarse grade, making it effective for initial surface prep and aggressive deburring cycles. At 3/4 inch in diameter, this disc suits tight-access work where larger discs cannot reach.

This disc is used in light industrial, maintenance, and fabrication environments where controlled surface conditioning is required on metal components. Typical applications include weld prep, edge deburring, corrosion removal, and pre-paint blending on ferrous and non-ferrous substrates. The open-web construction resists loading and helps the disc run cool, supporting consistent finish results over extended use. Trades that commonly reach for this disc include pipe fitters, welders, millwrights, and maintenance technicians working on equipment surfaces, tube ends, and structural fabrications.

Key Features

• Non-woven fiber construction conforms to contoured and irregular surfaces
• Coarse aluminum oxide mineral supports aggressive deburring and initial surface prep
• Open-web design resists loading and dissipates heat for consistent finishes
• Roloc quick-change attachment allows fast disc swaps in multi-step finishing processes
• 3/4 inch diameter suits tight-access and small-diameter work areas

Compatibility

Designed for use with Roloc-compatible right-angle die grinders and finishing tools that accept the standard Roloc quick-change attachment system.

Installation Notes

Mount the disc onto a Roloc-compatible mandrel before attaching to the tool spindle. Verify the tool RPM rating meets or exceeds the disc maximum rated speed before use. Wear appropriate eye and face protection during operation. Inspect the disc for damage before each use and discard if the non-woven substrate shows tears or if the Roloc button is compromised.
