• 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

The Standard Abrasives Aluminum Oxide Precision Cartridge Roll, model 726000, C4-ST, offers reliable performance for precision grinding. This cartridge roll is designed with an attached drive stem that helps eliminate loosening and vibration, ensuring longer and better use than conventional rolls.

Its solid construction supports high tolerance and precision grinding, making it suitable for demanding industrial applications. The model C4-ST is part of the trusted Standard Abrasives brand known for quality and durability.

Precise Size And Format

This cartridge roll measures 1 inch by 2-1/2 inches by 1/4 inch, making it compact enough to reach tight spots with high speed. Its straight cylinder shape easily follows contours, which is ideal for working on irregular surfaces.

The format includes a 1/4 inch affixed drive stem that protrudes about 5/8 inch into the core, allowing it to be used with larger rotary tools like die grinders or drills for smooth, controlled grinding.

Effective Grade And Backing

The product features a grade 60 aluminum oxide abrasive, which cuts sharp and is friable, meaning it fragments under heat and pressure to reveal fresh cutting edges. This grade is well-suited for a range of finishes from coarse to fine.

The abrasive is resin-bonded to a cloth backing with a closed-coat construction, covering 100 percent of the backing. This ensures a consistent finish and enhances the toughness and strength of the cartridge roll.

Multi-Layer Design Benefits

The multi-layer design continually reveals fresh abrasive as the top layers wear down, providing a continuous and consistent cut throughout the life of the roll. This self-trimming feature helps maintain performance over extended use.

Wrapping multiple layers of abrasive material into a roll adds sturdiness and durability. The secure bond between the mineral and backing also supports higher pressure applications, making it ideal for edge breaking and removing machine tool marks.

Pack Count And Applications

This product comes in a pack of 25 cartridges per carton, with 250 cartridges per case, offering ample supply for industrial use. Its small size and cylindrical shape make it perfect for grinding and deburring hard-to-reach areas on ferrous metals.

Recommended for use on grooves, slots, threads, and contoured surfaces such as car parts, this cartridge roll excels in high-speed applications requiring precision and stability, thanks to its secure drive stem and multi-layer construction.
