3M Cubitron II Fibre Disc 987C, 36+, 7 in x 7/8 in, Die 700BB, (25/Bag) Case of 100

• 3M Precision-Shaped Grain maintains super-sharp points that cut exceptionally fast with less pressure
• Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys
• Mineral runs cooler and disc life is significantly longer, completing more parts per disc and requiring fewer disc changes
• Reduces changeouts and downtime in robotic and pressure-assisted applications
• Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding or beveling

3M Cubitron II Fibre Disc 987C offers significant gains in productivity on medium to heavy-duty operations thanks to the exceptionally high-performing 3M Precision-Shaped Grain combined with a stiff fiber backing. This disc achieves a higher cut-rate, greater durability, and longer life than other fiber discs — all with less grinding pressure. 3M Cubitron II Fibre Disc 987C is powered by 3M Precision-Shaped Grain technology for heavy-duty metalworking applications. This mineral is an exceptionally high-performing ceramic, resin-bonded to a stiff fiber backing. 3M Fibre 987C products also incorporate a grinding aid to keep the workpiece cooler, protecting heat-sensitive alloys from heat damage and reducing re-work. These features offer increased productivity for heavy-duty grinding on all metals, including stainless steel.

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 Fibre Disc 987C will keep your robot grinding welds long after other abrasives call it quits, reducing downtime and maximizing efficiency.

About 3M Precision-Shaped Grain
To create 3M Precision-Shaped Grain, engineers start with 3M Ceramic Abrasive Grain and use 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, rather than gouging or plowing as traditional abrasive grains 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. The mineral also wears evenly, and because the abrasive stays cooler and sharper, 3M Cubitron II abrasives last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.

Trusted 3M Cubitron II

The 3M Cubitron II Fibre Disc 987C offers exceptional cutting performance thanks to its 3M Precision-Shaped Grain technology. This model is designed to maintain super-sharp points that cut fast with less pressure, making it ideal for heavy-duty metalworking.

With a stiff fiber backing and strong resin bond, the 987C disc is durable and tear-resistant. This ensures it can handle tough tasks like high-pressure weld grinding or beveling without wearing out quickly.

High Grade 36 Plus

This product comes in grade 36+, which balances aggressive cutting with long disc life. The mineral runs cooler during use, reducing heat buildup and protecting heat-sensitive alloys from damage.

Thanks to the grinding aid incorporated on the disc, it minimizes grinding temperatures, which helps reduce rework and keeps the workpiece in better condition during medium to heavy-duty operations.

Precise 7 Inch Size

The disc measures 7 inches in diameter with a 7/8 inch arbor hole, fitting many standard grinders. This size is versatile for various grinding tasks, including flame-cut edge cleanup and right angle grinding.

Its dimensions make it suitable for robotic and pressure-assisted applications, where consistent size and fit are crucial for reducing downtime and maximizing efficiency during weld grinding.

Convenient 25 Per Bag

Each bag contains 25 discs, and the product is sold as a case of 100, providing a large supply for ongoing projects. This pack size supports continuous work without frequent reordering.

The bulk packaging is especially useful for industrial settings where high volumes of grinding are needed, ensuring workers have enough discs on hand for heavy-duty metalworking tasks.

Effective Grinding Applications

The 3M Cubitron II Fibre Disc 987C is recommended for a variety of applications such as weld removal, edge chamfering, and gate removal. Its high-performance grain cuts cleanly and lasts longer than conventional discs.

Its design reduces changeouts and downtime, particularly in robotic weld grinding. This makes it a reliable choice for heavy-duty grinding on metals including stainless steel, enhancing productivity.
