3M™ Cubitron™ II Grinding Wheel is constructed of 3M precision-shaped ceramic grain to bring you an exceptionally fast-cutting and long-lasting rigid bonded wheel for heavy weld removal and other heavy-duty grinding applications. This grinding wheel works well on almost all materials and is specially formulated for use on stainless steel, mild steel, and aerospace alloys.

  • 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

  1. What are the dimensions of the 3M™ Cubitron™ II Depressed Center Grinding Wheel, and how many come in a case?

    The wheel is 7 inches by 1/4 inch by 5/8-11 inches. There are 10 wheels per inner pack and a total of 20 wheels per case.

  2. What makes this grinding wheel stand out from others?

    The innovative precision-shaped grain technology used in our Cubitron II line provides faster cutting speeds and longer life compared to other conventional abrasives.

  3. Can I use this grinding wheel for different types of materials?

    Yes, our Cubitron II Depressed Center Grinding Wheel can be used on stainless steel, mild steel, cast iron, aluminum and other metals with high efficiency.

  4. Is there any special care for storing these grinding wheels?

    For best results it’s recommended that you store them dry at room temperature or lower temperatures. Do not pile too high as weight may deform the boxes.

  5. . What is the T27 Quick Change designation refer to ?

    . T27 refers to Type-27 which means depressed center while Quick Change specification implies that clamps are locked using twist-on/twist-off action instead of nut & screw mechanism thus quick change option provide an easier way of changing discs/wheels on different tools as needed without requiring additional accessories such as spanners etc .

Cuts Fast and Cool

3M™ Cubitron™ II Depressed Center Grinding Wheel is designed to exceed the performance of other grinding wheels in both cut and life, resulting in significant gains in productivity. The power of 3M Precision-Shaped Grain provides a cool, extra-sharp, quick cut that lasts longer than other wheels.

Ideal for Robotic Weld Grinding

For medium and high-pressure applications like robotic weld grinding, it is crucial to choose a high-performance abrasive that cuts fast and lasts long. The self-fracturing mineral in 3M™ Cubitron™ II Depressed Center Grinding Wheel ensures that your robot can grind welds for a longer time, 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 are typically better for grinding welds on flat surfaces. A grinding wheel must be used with a right angle grinder that has a wheel guard designed for the size of the wheel used. Type 27 wheels have a depressed center that allows grinding at any angle without damaging the surrounding surface. 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 set a new standard for high-performing abrasives. 3M engineers used proprietary precision-shaped grain technology to maximize cutting potential, starting with 3M™ ceramic abrasive grain. Precision-shaped grain fractures into super-sharp points and edges that slice cleanly through metal, rather than plowing like traditional abrasives, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. 3M™ Cubitron™ II abrasives outcut and outlast competitive ceramic abrasives, maximizing productivity and minimizing operator fatigue.
