Abrasive Roloc Disc 3M 50 mm Medium SC-DR for Steel/Stainless Steel, model 7000000751

3M Roloc Disc 50 mm Medium SC-DR (model 7000000751) is a medium-grade abrasive disc designed for use on steel and stainless steel. The compact 50 mm size and Roloc quick-change mounting make this disc suitable for tasks that require access to confined spaces and fast disc replacement. Developed for surface blending, light deburring and edge conditioning, the medium grit provides an even balance between material removal and surface finish for workshop and industrial maintenance operations.

Advantages

The Roloc mounting system enables rapid, tool-free disc changes, reducing downtime during maintenance tasks. The medium abrasive grade delivers consistent cutting action on ferrous and stainless steels while preserving part geometry. Its small diameter allows improved access to tight areas and edges that larger abrasives cannot reach. The disc construction is balanced for controlled material removal and predictable finish quality when used with compatible rotary holders.

Suitable for

• Surface blending and finish refinement on steel and stainless steel
• Light deburring of edges and weld seams
• Edge conditioning and removal of minor burrs
• Maintenance and repair tasks in workshops and industrial settings

Key specifications

• Disc diameter: 50 mm
• Abrasive grade: medium
• Abrasive type: scotch-brite style non-woven conditioning material (SC-DR)
• Compatible mounting: Roloc quick-change system
• Recommended workpiece materials: steel and stainless steel
• Primary applications: surface blending, light deburring, edge conditioning

How to use

Fit the 50 mm Roloc disc onto a compatible Roloc holder according to the holder manufacturer's instructions, ensuring the disc is securely attached. Operate the rotary tool at the speed range recommended for non-woven abrasive discs and the workpiece material, applying light to moderate pressure and moving the disc evenly across the surface. Avoid excessive heat buildup by using intermittent passes and allow the workpiece to cool if necessary. Replace the disc when abrasive performance or surface finish degrades.

Recommendations

Use personal protective equipment such as safety glasses, gloves and appropriate respiratory protection. Verify compatibility of the Roloc holder and the tool's maximum RPM with the disc. For best results, test on a scrap piece first to establish optimal feed, pressure and speed for the specific steel or stainless steel alloy.
