3M Cubitron 3 Series Fibre Disc, 76.2mm Disc Diameter, 80 Grit size - 7100332357

This Fibre disc is a coated abrasive engineered for high-speed surface preparation and metalworking tasks. It attaches via a quick-change Roloc-style system and is intended for grinding, weld blending and medium-pressure surface finishing in automated and manual workflows across electronics, electrical and mechanical environments.

Features & Benefits

• Precision-shaped ceramic grain reduces operator pressure and effort
• Fibre backing increases stiffness and resists tearing
• Rated safe to 15,000 r/min for high-speed operations
• Re-engineered mineral maintains Sharp cutting points longer
• Quick-change attachment reduces downtime between grades

Applications

• Suitable for weld removal on mild and carbon steels
• Used for bevel preparation on fabricated components
• Ideal for robotic grinding stations in production lines
• Suitable for medium-pressure surface grinding prior to coating
• Can be used for blending and finishing electrical enclosure parts

What attachment method enables Rapid disc swaps?

A Roloc-compatible quick-change mounting allows fast grade changes without tools, improving throughput.

How does the abrasive reduce heat transfer to workpieces?

The precision-shaped ceramic grain cuts with less applied force, producing lower friction and reduced risk of metal discolouration.

What packaging quantity is supplied for continuous operations?

The product is supplied in bulk packs of 50 to minimise changeovers and support high-volume use.

Which backing material supports heavier grinding loads?

A stiff Fibre backing provides structural support and enhanced tear resistance for demanding applications.

How does the disc perform across varying pressures?

The abrasive maintains cutting points over its life, delivering consistent material removal from medium to heavier contact pressures.
