3M Cubitron 3 Precision Shaped Grain Grinding Disc, 180 mm, 80+ Grit 100 Per Pack

This Fibre disc is a high-performance abrasive designed for heavy-duty metal removal in industrial settings. It employs a precision-shaped abrasive to maintain cutting efficiency while running cooler, and is built with a robust Fibre backing for demanding grinding tasks. Supplied in packs to support continuous production, it is intended for use with compatible rotary grinding equipment operating within safe rotational limits.

• Re-engineered precision-shaped grain delivers Faster sustained cut rates
• Sharp, angular abrasive fractures to retain cutting points
• Strong resin bond improves tear resistance during heavy work
• Runs cooler to reduce metal discolouration risk
• Consistent wear pattern reduces disc changeouts

• Suitable for weld removal on steel components
• Ideal for bevel preparation in robotic grinding cells
• Used for medium-to-high pressure metal grinding operations
• Can be used for surface preparation before coating or finishing
• Suitable for automated and manual fabrication workflows

A stiff Fibre backing provides structural support and resistance to tearing under medium-to-high pressure contact.

The shaped abrasive produces a cooler cutting action, requiring less operator pressure and helping to limit heat transfer that can cause discolouration or stress cracks on mild and carbon steels.

The discs are supplied in bags of 25 to facilitate stocking and minimise downtime from frequent replenishment.

The disc is specified for use below its maximum safe rotational speed
