Available in coarse grades, the Standard Abrasives Zirconia Cartridge Roll is ideal for high-speed grinding and deburring on all metals. Its small size and shape enable it to blend and deburr inside holes and diameters of machined parts or on irregular surfaces and contours.

Recommended Applications
Choose a Standard Abrasives Zirconia Cartridge Roll when you need to grind or deburr small or confined spaces of the workpiece. It is ideal for getting into grooves, slots, threads or channels, punched or drilled holes, and contoured surfaces such as car parts. Combining an aggressive cut with durability makes it a great solution for edge breaking and removal of machine tool marks or flash.

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.

Using a Cartridge Roll on a High-Speed Tool
The cartridge roll has an arbor hole to accommodate a mandrel tool attachment (sold separately), which attaches to a rotary tool such as a die grinder or drill. The mandrel should have a pilot length no less than 1/2˝ shorter than the length of the cartridge roll.

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.

Trusted Brand And Model

The Standard Abrasives Zirconia Cartridge Roll, model 727338 CR-ST, is designed for reliable performance. This product carries the trusted Standard Abrasives brand known for quality in metalworking supplies.

Its specific model number 727338 and CR-ST format ensure you get the exact cartridge roll suited for your grinding and deburring needs. The brand’s reputation supports consistent results in industrial applications.

Precise Size And Dimensions

This cartridge roll measures 1/4 inch by 1-1/2 inch by 1/8 inch, making it compact and easy to maneuver. Its small size helps operators reach tight spots and intricate contours during high-speed grinding tasks.

These exact dimensions allow the roll to fit into grooves, slots, and holes on machined parts, providing effective deburring and blending on irregular surfaces. The size supports detailed work on metal components.

Durable Grade And Material

The roll uses a 60-grade zirconia alumina abrasive, known for its toughness and long-lasting cutting ability. This coarse grade is ideal for heavy stock removal and aggressive grinding on ferrous and non-ferrous metals.

Zirconia alumina fractures under pressure to expose fresh sharp points, delivering a faster cut rate than aluminum oxide. This makes it perfect for edge breaking and removing machine tool marks efficiently.

Effective Format And Design

The cartridge roll comes in a straight cylinder format, which is excellent for accessing curves on stamped or rounded parts. This shape complements the roll’s ability to work inside holes and diameters of machined pieces.

Its multi-layer design continually reveals fresh abrasive layers as the top wears down, ensuring consistent cutting performance. The resin bond and closed-coat construction enhance durability and provide a smooth finish.

Convenient Pack Size Count

This product is supplied in a pack of 100 pieces per case, making it easy to stock up for ongoing projects. The large quantity supports continuous work without frequent reordering.

Having 100 cartridge rolls available means you can maintain productivity in high-speed grinding and deburring tasks, especially when working on multiple parts or large batches.
