• 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 C

The Standard Abrasives A/O Precision Cartridge Roll, model 726007 C3-ST, offers reliable performance with its attached drive stem that reduces loosening and vibration. This design ensures longer life and better results compared to conventional cartridge rolls.

Model C features an affixed 1/4 inch drive stem that extends about 5/8 inch into the core, making it suitable for use with larger tools. This secure stem attachment supports smooth, controlled grinding at high speeds.

Precise Size And Format

This cartridge roll measures 13/16 inch by 2-1/2 inch by 1/4 inch, making it compact enough to reach tight spots with ease. Its straight cylinder shape allows it to follow contours smoothly for precision grinding on irregular surfaces.

The format comes in packs of 25 cartridges per roll and 250 rolls per case, providing ample supply for industrial or workshop use. This size and packaging support efficient workflow and easy inventory management.

Multi-Layer Abrasive Design

The multi-layer construction continually exposes fresh abrasive material as the top layers wear down, extending the roll’s life and maintaining consistent cutting performance. This design helps keep the cartridge roll sharp and effective throughout its use.

Wrapped layers contribute to the roll’s durability and toughness, while the resin bond securely anchors the aluminum oxide abrasive to the cloth backing. This closed-coat construction ensures a smooth and uniform finish on ferrous metals.

Aluminum Oxide Grade Range

The product uses aluminum oxide mineral, known for its sharp cutting ability and friable nature, which fragments under heat and pressure to reveal new cutting edges. Grades range from 40 to 180, offering finishes from coarse to fine.

This broad grade range allows users to select the right abrasive strength for various applications, including edge breaking, deburring, and removal of machine tool marks on ferrous metals.

Industrial Application Benefits

Designed for high-speed grinding and deburring, this cartridge roll excels on irregular contours and hard-to-reach areas such as grooves, slots, and threads. Its solid construction supports high tolerance and precision work.

The secure bond between the roll and drive stem eliminates vibration, making it ideal for demanding industrial tasks. Its small size and cylindrical shape enable it to access tight spaces on machined parts efficiently.
