Product Description ------------------- 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. From the Manufacturer --------------------- The 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 wheel works well on almost all materials and is specially formulated for use on stainless steel, mild steel, and aerospace alloys. Its performance 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. Using Type 27 Grinding Wheels 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. Type 27 wheels with a quick-change attachment have a threaded center hole that enables easy, secure attachment to the tool without the use of a nut. The grinding wheel must have a maximum operating speed greater than or equal to the maximum speed of the grinder used. Experience the Powerful Performance of 3M™ Cubitron™ II 3M Cubitron II products have raised the bar for high-performing abrasives. 3M precision-shaped ceramic grain (PSG) outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. The result is that operators can grind faster and complete more parts per disc with less muscle-work and igue. To create PSG, 3M engineers started with 3M ceramic abrasive grain and used proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal like a through butter, rather than gouging or plowing as traditional abrasives do, and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration. PSG also wears evenly, and because the abrasive itself stays cooler and sharper, Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.
