Cuts Fast and Cool
We made our 3M™ Cubitron™ II Depressed Center Grinding Wheel to perform at a level that surpasses competitive wheels in both cut and life to deliver significant gains in productivity. Experience the power of 3M Precision-Shaped Grain to provide a cool, extra-sharp, quick cut long after other wheels are consumed.

Ideal for Robotic Weld Grinding
In medium and high-pressure applications like robotic weld grinding, it's important to choose a high-performance abrasive that cuts fast and lasts long. The self-fracturing mineral in 3M™ Cubitron™ II Depressed Center Grinding Wheel will keep your robot grinding welds long after other abrasives call it quits, reducing downtime and maximizing efficiency.

Grinding Wheel: Tips for Optimum Use
A grinding wheel is a rigid resin-bonded wheel that is approximately 1/4" thick and is useful for removing welds from internal angles. Fiber discs, on the other hand, typically work best for grinding welds on flat surfaces. A grinding wheel must be run on a right angle grinder with a wheel guard that is designed specifically for the size of wheel used. Type 27 wheels have a depressed center to allow grinding at any angle without damaging the surrounding surface with the attachment. The grinding wheel must have a maximum operating speed greater than or equal to the maximum speed of the grinder used.

3M Precision-Shaped Grain Maximizes Cutting Potential
3M™ Cubitron™ II products have raised the bar for high-performing abrasives. Our team of 3M engineers started with 3M™ ceramic abrasive grain and used proprietary precision-shaped grain technology to maximize cutting potential. Precision-shaped grain continually fractures into super-sharp points and edges that slice cleanly through metal like a knife, rather than plowing as traditional abrasives do, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. We are proud to say that 3M™ Cubitron™ II abrasives outcut and outlast competitive ceramic abrasives, maximizing productivity and minimizing operator fatigue.

  • 3M Precision-shaped grain engineered to cut faster than competitive ceramic products, offering significant productivity gains
  • Triangular shaped ceramic grain wears evenly, runs cool, and optimizes mineral breakdown, for extra-long life
  • Reduces changeouts and downtime in robotic and pressure-assisted applications
  • Rigid, reinforced resin-bonded wheel slices through almost all materials including stainless steel, mild steel, and aerospace alloys
  • Wheel must have a maximum operating speed greater than or equal to the maximum speed of the power tool used
  • Must be used with ANSI-approved guard that fits the size of the wheel
