• 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.

Standard Abrasives Model C

The Standard Abrasives A/O Precision Cartridge Roll, model 726012 C3-ST, offers reliable performance with its attached drive stem that reduces loosening and vibration. This design ensures longer-lasting use compared to conventional cartridge rolls, making it a dependable choice for precision grinding tasks.

Its affixed 1/4 inch drive stem protrudes about 5/8 inch into the core, allowing compatibility with larger tools. This feature supports smooth, controlled high-speed grinding, ideal for demanding industrial applications.

Compact Size For Precision

Measuring 13/16 inch by 2-1/2 inch by 1/4 inch, this cartridge roll’s small size enables operators to reach tight spots with ease. Its straight cylinder shape follows contours smoothly, making it perfect for detailed work on irregular surfaces.

The compact dimensions allow it to access grooves, slots, threads, and channels, especially on contoured parts like automotive components. This makes it a versatile tool for precision deburring and edge breaking.

Multi-Layer Abrasive Design

The multi-layer construction continually exposes fresh abrasive material as the top layers wear down. This self-trimming feature extends the roll’s life and maintains consistent cutting performance throughout use.

Wrapped tightly into a roll, the layers provide durability and toughness. The closed-coat design covers 100 percent of the backing, ensuring a smooth, uniform finish on all ferrous metals.

Aluminum Oxide Abrasive Grades

This cartridge roll uses aluminum oxide mineral, known for its sharp cutting and friable nature. The model C3 grade 60 offers a balance of aggressive cutting and durability, suitable for a range of finishes from coarse to fine.

Aluminum oxide’s ability to fragment under heat and pressure reveals new cutting edges, making it effective for removing machine tool marks and flash. This grade range supports various industrial grinding needs.

Pack Size And Format

The product comes in a convenient pack of 25 cartridges per pack, with 250 cartridges per case. This format supports efficient inventory management and continuous workflow in busy shops.

The cartridge roll format, combined with the attached drive stem, fits rotary tools like die grinders or drills. This setup allows operators to apply more pressure and achieve high tolerance grinding results.
