This 3M Cubitron 3 Fibre Disc is a high-performance abrasive solution designed for aggressive removal of material, primarily on metals. It uses Precision Shaped Ceramic grain technology to cut faster and run cooler than traditional abrasives, which saves you time and reduces the chance of heat discoloration on your workpiece.
- The Precision Shaped Ceramic grain maintains a sharp edge throughout the disc’s life, significantly increasing the disc’s durability so you don’t have to stop to change discs as often.
- The 36+ grit rating and ceramic construction are engineered for high stock removal applications like heavy weld removal and beveling, drastically improving your grinding efficiency.
- These discs are robust and run cooler, which contributes to a safer operation by reducing heat build-up that can weaken the disc or the material being worked on.
Who this is best for
This disc is ideal for heavy fabrication shops, foundries, shipbuilding, and any industrial environment performing aggressive material removal, grinding, or weld prep on carbon steel, stainless steel, or other hard metals.
