3M Cubitron 3 Series Fibre Disc, 50.8mm Disc Diameter, 80 Grit size - 7100331753

This Fibre disc is a high-speed abrasive designed for material removal and surface finishing in industrial settings. It uses precision-shaped ceramic grain on a Fibre backing to deliver aggressive cutting with reduced operator pressure. The disc is intended for use with rapid-rotation hand and power tools in automation, electronics, electrical and mechanical workshops where controlled removal and surface preparation are required.

Features & Benefits

• Precision-shaped ceramic grain reduces required cutting pressure
• Grinding aid lowers temperatures on heat-sensitive alloys
• Stiff Fibre backing resists tearing during heavy use
• Strong resin bond extends service life under load
• Quick Roloc attachment enables Rapid disc changes
• Rated maximum safe speed 15,000 r/min for high-speed tools

Applications

• Suitable for weld removal on stainless steel components
• Ideal for bevel preparation on metal housings
• Used for blend and finish on non-ferrous assemblies
• Can be used for robotic grinding stations in production
• Suitable for medium-pressure surface preparation prior to coating

What centre-mount compatibility does it have for angle grinders?

It features a 22mm centre hole that mates with Roloc-style attachments and compatible back-up pads for Rapid attachment.

How is heat generation managed during use on stainless steel?

An incorporated grinding aid reduces frictional heat and helps limit metal discolouration and stress cracking on heat-sensitive alloys.

What packing quantity is supplied for production environments?

The product is supplied in packs of 50 to support batch operations and reduce changeovers.

Which abrasive grade is supplied for coarse material removal?

The discs are supplied in an 80 grit specification for aggressive stock removal while maintaining workpiece control.

What colour and backing type identify the discs for inventory control?

The discs are purple and use a Fibre backing to provide durability and tear resistance during robust applications.
