3M Cubitron 3 Series Fibre Disc, 125mm Disc Diameter, 80 Grit - 7100349571

This Fibre disc is a 125mm abrasive for heavy-duty material removal and finishing in industrial settings. It employs an engineered ceramic abrasive in a resilient Fibre backing and is intended for use on angle grinders and similar rotary tools where controlled, efficient grinding and weld preparation are required.

Features & Benefits

• Precision-shaped ceramic grain reduces cutting force and heat
• High sustained cut rate increases parts processed per disc
• Stiff Fibre backing resists tearing during high-pressure work
• Strong resin bond maintains abrasive integrity under load
• Slotted design improves debris evacuation and cooling

Applications

• Suitable for robotic welding cell bevelling and prep
• Ideal for weld removal on carbon and mild steel
• used with angle grinders for metal surface levelling
• Can be used for medium- to high-pressure grinding tasks

What centre mounting does it require for compatibility with grinders?

It fits a 22mm centre hole, matching standard 125mm grinder backings for secure attachment.

How should operators manage speed to avoid damage?

Maximum safe rotational speed is 250 r/min

do not exceed this to prevent premature failure.

How does the disc perform under varied pressure levels?

The abrasive maintains Sharp cutting points across a range of application pressures, providing consistent material removal and predictable wear.

What packaging and quantities are supplied for site stocking?

The discs are supplied in packs of 25, enabling straightforward replenishment and jobsite rotation.

What colour coding aids Visual identification on-site?

The discs are finished in yellow to assist Rapid selection among abrasive inventories.
