3M Cubitron 3 Precision Shaped Ceramic Grain Grinding Disc, 50 mm, 50 Grit 200 Per Pack

This Fibre disc is a purple, Fibre-backed abrasive designed for industrial metalworking and surface preparation on high-speed rotary tools. It uses precision-shaped ceramic grain to deliver aggressive cutting while reducing operator effort, and it is intended for applications where predictable wear, reduced metal discolouration and efficient material removal are required.

• Precision-shaped ceramic grain reduces operator pressure while cutting
• Stiff Fibre backing offers tear resistance during heavy grinding
• Strong resin bond prolongs disc life under medium-pressure use
• Maintains Sharp points for consistent cutting throughout life
• Compatible with quick Roloc attachment for fast disc changes
• Rated maximum safe speed 15,000 r/min for high-RPM operations

• Suitable for weld removal on mild and carbon steels
• Ideal for bevel preparation prior to assembly
• Used for robotic grinding operations in automated cells
• Can be used for surface blending and profile finishing
• Suitable for medium-pressure surface preparation in workshops

The disc has a 22mm centre hole to fit compatible quick-attach spindles and Roloc-style adaptors.

The abrasive’s geometry requires less applied pressure, which helps reduce frictional heat and lowers the risk of metal discolouration and stress cracking.

The discs are packaged in quantities of 50 per carton to support high-volume industrial use.

A precision-shaped ceramic grain is employed to sustain Sharp cutting points and deliver Faster material removal across varied pressures.
