Standard Abrasives Zirconia Precision Cartridge Roll Model C is ideal for high-speed, heavy-pressure grinding and deburring on irregular contours and hard-to-reach areas on all 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™ Zirconia Precision Cartridge Roll Model C (formerly 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 shape pass 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, punched or drilled holes, 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.

Heavy-duty zirconia alumina is well-suited for coarse stock removal on all metals, including stainless steel. Combining an aggressive cut with durability makes it 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 heavier pressure with larger tools.

Cartridge rolls are either straight or tapered. Straight rolls are cylindrical and effective at getting into curves on stamped or rounded parts. Tapered rolls are cone shaped and allow better reach into punched or drilled holes.

Durable Zirconia Alumina for Coarse Applications
Zirconia Alumina fractures frequently under heavy pressure to continually produce fresh sharp points and delivers a faster cut-rate than aluminum oxide. A man-made mineral, it is well-suited for coarse grits, heavy stock removal and high pressure grinding.

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 Zirconia Precision Cartridge Roll, model 726124 C1-ST, offers reliable performance for high-speed grinding and deburring. This model features a 1/4 inch drive stem securely affixed to the roll, ensuring stability during use.

Its design supports heavy-pressure applications on ferrous and non-ferrous metals. The Model C is especially suited for use with larger tools, providing smooth and controlled grinding thanks to its solid construction.

Precise Size And Format

This cartridge roll measures 1/2 inch by 2-1/2 inches by 1/4 inch, making it compact enough to reach tight spots with ease. The straight cylinder shape helps it follow contours, while the size allows access to grooves, slots, and holes.

Its format as a precision cartridge roll enables operators to work on irregular contours and hard-to-reach areas. The small size combined with the 1/4 inch stem enhances versatility for detailed grinding tasks.

Durable Zirconia Alumina Grade

The roll uses an 80 grit zirconia alumina abrasive, known for its long-lasting durability and aggressive cut. This grade is ideal for coarse stock removal on all metals, including stainless steel, making it effective for edge breaking and flash removal.

Zirconia alumina fractures under pressure to expose fresh sharp points, maintaining a fast cut rate. This makes the cartridge roll suitable for heavy-duty grinding and deburring applications requiring consistent performance.

Multi-Layer Abrasive Design

The cartridge roll features a multi-layer design that continually reveals fresh abrasive as the top layers wear down. This self-trimming capability extends the life of the roll and ensures a consistent cut throughout its use.

Wrapped layers contribute to the roll’s sturdiness and durability. The resin bond anchors the abrasive securely to the cloth backing, providing toughness and a smooth, consistent finish on metal surfaces.

Convenient Pack Size Options

This product comes in a pack of 25 rolls per carton and 250 rolls per case, making it easy to stock for industrial or workshop needs. The packaging supports efficient inventory management for frequent use.

Having multiple rolls on hand ensures uninterrupted work on projects requiring precision grinding. The pack size complements the roll’s design for high tolerance and precision applications on various metal parts.
