- Ideal for general purpose sanding on wood, metal, plastic, dry wall, fiberglass, glass, clear coat, and ceramic
- Open coat construction provides aggressive cut and reduced loading
- Anti-load coating helps prevent clogging and produce consistent finishes
- Light, A-weight paper flexes with the backup pad
- 3M™ Stikit™ adhesive provides fast attachment and clean removal for multi-step finishing processes
3M™ Stikit™ Paper Disc Roll 426U are multiple sanding discs packaged in a roll for convenience and use in high-production environments and ideal for white wood sanding, sealer sanding, solid surface or where fine finish is critical. The disc itself features silicon carbide abrasive with a load-resistant coating and open coat abrasives that work together to minimize loading.
We chose silicon carbide abrasive, which is fast cutting, creates a smoother finish than aluminum oxide or garnet abrasives, and is effective for finishing on hard woods and solid surfaces. Constructed with A-weight, light paper and a pressure sensitive adhesive (PSA) backing, this disc will flex with the backup pad and flow over contours to produce consistent finishes. The adhesive holds the disc securely during use and provides quick and easy change out for multi-step sanding and finishing processes. These discs are suited for rotary and random orbital sanders. Applications include general sanding, finishing, blending, surface leveling, and prep prior to staining or painting, and bare wood sanding.
Sanding discs cut better and last longer when dust isn’t loading the cutting surface of the abrasives. Loading occurs when wood or paint dust clogs the surface of the disc and the abrasive points, which can quickly make the disc ineffective. Open coat construction means the abrasive grains are spaced so that dust and debris can collect in the spaces rather than loading the disc. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade, for faster results.
Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as white wood sanding, finishing and paint prep. While it breaks down faster than aluminum oxide, it produces a superior finish.
Our 3M™ Stikit™ products are designed to handle a wide range of sanding and finishing needs. These high-quality abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so they conveniently press on to a backup pad or hand pad, and remove cleanly, leaving an uncontaminated surface for the next disc.

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.
Stands up to high-pressure grinding
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.

3M Precision-Shaped Grain
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.
