3M 7010329424 Scotch-brite Roloc Se-dr Disc 4 Inch Medium

Product Description

The 3M 7010329424 is a Scotch-Brite Roloc SE-DR surface conditioning disc designed for heavy-duty deburring and finishing on metal workpieces. Built from a coarse, non-woven aluminum oxide fiber construction, the disc conforms to irregular and contoured surfaces, removing burrs and conditioning the finish without gouging or undercutting the base material. At 4 inches in diameter and rated medium grade, it is suited for aggressive material removal while running cool to produce consistent results across multiple passes. Metalworkers, fabricators, and maintenance technicians typically reach for this disc when cleaning welds, blending surfaces, or preparing metal for coating.

This disc is used in metal fabrication, maintenance, and surface prep applications where contour conformability matters. The open-web non-woven construction resists loading, which extends disc life compared to coated abrasives in many finishing scenarios. It attaches via the Roloc quick-change system, making it practical for multi-step finishing operations where disc changes need to happen fast. Typical applications include deburring drilled or punched holes, weld blending, and light-to-medium stock removal on ferrous and non-ferrous metals.

Key Features

• Non-woven aluminum oxide construction for aggressive deburring and surface conditioning
• Conforms to irregular and contoured surfaces without gouging or damaging base material
• Open-web design resists loading and runs cool for consistent, repeatable finishes
• Roloc quick-change backing allows fast disc swaps during multi-step finishing processes
• Medium grade balances cut rate with surface finish quality

Compatibility

Designed for use with Roloc quick-change right-angle grinders and die grinders that accept the standard Roloc attachment system. Verify tool RPM rating does not exceed the maximum rated speed of the disc before use.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from the air supply or electrical source. Thread the Roloc disc firmly onto a compatible Roloc mandrel until the disc seats fully against the backing pad. Always confirm the tool's free speed does not exceed the disc's maximum rated RPM before operation. Wear appropriate PPE including eye and face protection when operating any abrasive disc.
