Disco abrasivo Roloc 3M 50 mm fino SC-DR para aço e aço inoxidável (modelo 7000000750)

3M Roloc Disc 50 mm Fine SC-DR is a quick-change abrasive disc designed for controlled surface finishing on steel and stainless steel. The 50 mm diameter and fine abrasive grade provide even material removal for tasks such as weld blending, light deburring and surface cleaning. The disc attaches to Roloc-type quick-mount holders for fast tool changes and consistent contact on workpieces.

Advantages

The fine SC-DR abrasive offers predictable cutting action with reduced risk of over-grinding, producing a uniform satin finish on ferrous and stainless surfaces. Quick-change Roloc mounting saves time during tool swaps and improves workflow efficiency. The compact 50 mm size provides access to confined areas and precise control on small parts, while the abrasive construction resists loading and maintains cutting performance during light finishing operations.

Suitable for

• Weld blending and smoothing on steel and stainless steel
• Removing light burrs and flash from machined or stamped parts
• Surface cleaning and preparation before painting or further finishing
• Finishing in tight or confined spaces where larger discs are impractical

Key specifications

• Disc diameter: 50 mm
• Abrasive grade: Fine
• Suitable materials: Steel, stainless steel
• Mounting system: Roloc-type quick-mount
• Primary applications: Surface finishing, blending, light deburring

How to use

Mount the disc onto a compatible Roloc quick-mount holder and secure it according to the tool manufacturer's instructions. Use moderate, even pressure and let the abrasive do the work; avoid excessive force which can shorten disc life or create uneven results. Keep the tool speed within recommended ranges for the abrasive type and material being worked. Move the disc across the surface in smooth strokes to achieve uniform finish and avoid dwelling in one area.

Recommendations

For best results, test the disc on a scrap piece to verify finish and speed settings before working on critical parts. Use appropriate personal protective equipment, including eye protection, gloves and respiratory protection when generating dust. Replace the disc if it shows excessive wear or reduced cutting action to maintain consistent results.
