• 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

The Standard Abrasives A/O Precision Cartridge Roll, model 726028 C3-ST, offers reliable performance for precision grinding tasks. This model features an attached drive stem that helps prevent loosening and vibration, ensuring longer-lasting use compared to conventional cartridge rolls.

Designed for high tolerance and precision grinding, this cartridge roll is resin-bonded to the inner layers for solid construction. It’s ideal for use with larger tools, providing smooth and controlled operation during high-speed applications.

Precise Size And Format

This cartridge roll measures 13/16 inch by 2-1/2 inches by 1/4 inch, making it compact enough to reach tight spots with ease. Its straight cylinder shape allows it to follow contours smoothly, which is essential for working on irregular surfaces and hard-to-reach areas.

The format includes a 1/4 inch affixed drive stem that protrudes about 5/8 inch into the core. This design supports use with rotary tools like die grinders or drills, enabling operators to apply more pressure and maintain control during grinding.

Wide Grade Range

The cartridge roll comes in grade 180, part of a range from 40 to 180, allowing users to select the right abrasive for their specific finish needs. Aluminum oxide mineral cuts sharp and fragments under heat and pressure to reveal fresh cutting edges continuously.

This broad grade spectrum supports finishes from coarse to fine, making the roll suitable for various applications, including edge breaking and removal of machine tool marks or flash on ferrous metals.

Multi-Layer Abrasive Design

The multi-layer design of this cartridge roll ensures longevity by continually exposing fresh abrasive material as the top layers wear down. This self-trimming feature maintains a consistent cut and performance throughout the roll’s life.

Wrapped tightly into a roll, the multiple layers add sturdiness and durability. The closed-coat construction covers 100 percent of the cloth backing, providing a smoother and more consistent finish on the workpiece.

Pack Count And Applications

This product is supplied in packs of 25 cartridges per pack, with 250 cartridges per case, making it convenient for industrial use and bulk purchasing. Its small size and shape make it perfect for grinding and deburring grooves, slots, threads, and contoured surfaces.

Ideal for use on ferrous metals, the cartridge roll excels in high-speed grinding on irregular contours and hard-to-reach areas. Its secure bond to the drive stem eliminates vibration, supporting precision work on machined parts.
