• Attached drive stem helps eliminate loosening and vibration for longer and better performance than a conventional cartridge roll
• Model C has an affixed 1/4˝ drive stem that protrudes about 5/8˝ into the core and is suitable for use with larger tools
• Multi-layer design continually reveals fresh abrasive for longevity
• Small size enables operators to reach tight spots with high speed
• Solid construction excels at high tolerance and precision grinding
• Straight cylinder shape follows contours easily
• Suitable for use on ferrous metals

Standard Abrasives Aluminum Oxide Precision Cartridge Roll Model C is ideal for high-speed grinding and deburring on irregular contours and other hard-to-reach areas on all ferrous metals. The drive stem is securely affixed within the roll and resin-bonded to the inner layers. This solid construction supports use with larger tools and higher pressure, and enables a smoother application.

Recommended Applications
Choose a Standard Abrasives Silicon Carbide Precision Cartridge Roll Model C (formerly a Kay Roll) when you need added abrasive stability for grinding or deburring applications on hard-to-reach areas of the workpiece. Its small size and cylindrical shape passes easily over and into irregular contours and enable it to reach into holes and diameters of machined parts. It is ideal for getting into grooves, slots, threads or channels, and contoured surfaces such as car parts.

The secure bond of the roll to the drive stem eliminates loosening and vibration, making our Precision Cartridge Roll especially beneficial when high tolerance and precision grinding are required. The multiple layers provide self-trimming capability during use, exposing new abrasive cutting points throughout the life of the roll. Combining an aggressive cut with durability makes this roll a great solution for edge breaking and removal of machine tool marks or flash.

Running a Cartridge Roll on a High-Speed Tool
The Model C cartridge roll has an affixed 1/4˝ stem that reaches 5/8˝ into the core and is bonded to the abrasive backing. This stem attaches to a rotary tool such as a die grinder or drill for smooth, controlled high-speed grinding. The protruded stem allows the operator to apply more pressure with larger tools.

Aluminum Oxide Cartridges Offer a Broad Range of Options
We offer Aluminum Oxide Precision Cartridge Rolls in a wide variety of sizes and grades to suit particular contours and different applications. For Model C, grades range from 40-180, producing a spectrum of finishes from coarse to fine. Aluminum oxide mineral cuts sharp and is friable – fragmenting under heat and pressure to reveal sharp cutting edges as it abrades the surface.

Benefits of a Multi-Layer Design
Seemingly small, these cartridge rolls conquer big challenges when space gets tight. The multi-layer, multi-wear design of a Standard Abrasives Cartridge Roll keeps it cutting sharp and helps it withstand repeated wear. As top layers wear down with use, underlying layers expose fresh mineral, so you get a continuous and consistent cut, part after part. Wrapping multiple layers of the abrasive material around into a roll contributes to its sturdiness and durability.

A resin bond securely anchors mineral to the cloth backing – also enhancing the abrasive's toughness and strength. The closed-coat construction means mineral grains cover 100 percent of the cloth backing, so that a smoother, more consistent finish is achieved.

Quality Standard Abrasives Solutions for Industrial Applications
The Standard Abrasives brand has supplied quality abrasives to the metalworking industry for over 50 years. Customers rely on our broad offering of high performance products including coated, bonded, and non-woven abrasive lines.

Standard Abrasives Model

The Standard Abrasives A/O Precision Cartridge Roll, model 726070, C2-ST, offers reliable performance for precision grinding. This cartridge roll features an attached drive stem that reduces loosening and vibration, ensuring longer-lasting use compared to conventional rolls.

Designed specifically for high tolerance and precision grinding, this model supports smooth operation with larger tools. Its solid construction and resin bond provide durability and stability during demanding tasks.

Precise Size And Format

This cartridge roll measures 5/8 inch by 2-1/2 inches by 1/4 inch, making it compact enough to reach tight spots with high speed. The small size and straight cylinder shape allow it to follow contours easily, ideal for detailed work on irregular surfaces.

Its format as a precision cartridge roll with an affixed 1/4 inch drive stem ensures compatibility with rotary tools like die grinders or drills. This setup allows operators to apply more pressure and maintain control during use.

Durable Multi-Layer Design

The multi-layer design of this Standard Abrasives cartridge roll continually reveals fresh abrasive layers, extending its lifespan. As the outer layers wear down, new abrasive cutting points become exposed, maintaining consistent cutting performance.

Wrapped tightly into a roll, the layers contribute to the product’s sturdiness and durability. The closed-coat construction covers 100 percent of the cloth backing, producing a smoother and more consistent finish on workpieces.

Aluminum Oxide Abrasive Grade

This cartridge roll uses aluminum oxide mineral in grade 60, providing an aggressive cut with durability. Aluminum oxide is known for fragmenting under heat and pressure, which exposes sharp cutting edges for effective grinding.

Available in a range of grades from 40 to 180, the aluminum oxide rolls suit various finishes from coarse to fine. The grade 60 in this product balances cutting power and finish quality for many metalworking applications.

Pack Count And Applications

The product comes in a pack of 25 cartridges per roll, with 250 rolls per case, supporting large-scale industrial use. This quantity ensures a steady supply for ongoing grinding and deburring tasks.

Ideal for use on ferrous metals, the cartridge roll excels at reaching grooves, slots, threads, and contoured surfaces. Its design supports edge breaking and removal of machine tool marks or flash in hard-to-reach areas.
