3M Cubitron 3 Series Fibre Disc, 50.8mm Diameter, 60 Grit - 7100331745

This Fibre disc is a high-speed abrasive accessory designed for metalworking and surface-finishing tasks in industrial settings. It is intended for attachment to quick-change systems on portable grinders and robotic spindles, delivering controlled material removal on stainless steel, non-ferrous metals and general weld blending while operating at elevated rotational speeds.

Features & Benefits

• Precision-shaped ceramic grain maintains Sharp cutting points
• Grinding aid reduces heat generation on heat-sensitive alloys
• Stiff Fibre backing provides tear resistance under load
• Formulation sustains predictable wear for longer runtime
• Quick-change attachment enables fast disc swaps between tasks

Applications

• Suitable for weld removal on stainless steel components
• Ideal for bevel preparation in mechanical fabrication
• Used for blending and finishing non-ferrous metal surfaces
• can be used in robotic grinding stations for high-volume work
• Suitable for medium-pressure surface grinding in electrical housings

What attachment system does it use for Rapid changes?

It fits a Roloc-style quick-change system to allow fast switching between abrasive grades without additional tools.

How does it affect thermal impact on workpieces during grinding?

An integrated grinding aid lowers operating temperatures, helping to reduce metal discolouration and the risk of stress cracks on heat-sensitive alloys.

What performance behaviour can be expected across a disc's life?

The abrasive maintains cutting geometry to deliver consistent cut rates and predictable wear from initial use through end of life.

What backing characteristics support heavy-duty use?

A rigid Fibre backing combined with a strong resin bond offers strength and resistance to tearing under medium to high-pressure operations.
