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.

With a pack count of 100 pieces per case, this cartridge roll supports high-volume projects. Its proven track record makes it a dependable choice for professionals needing efficient abrasive solutions.

Precise Size And Format

This cartridge roll measures 1/4 in x 1-1/2 in x 1/8 in, providing a compact size ideal for detailed work. The straight format design allows easy access to tight spots and curved surfaces on machined parts.

Its small dimensions enable operators to reach grooves, slots, and irregular contours with high-speed tools. The straight cylinder shape is perfect for blending and deburring inside holes and diameters.

Effective Zirconia Alumina Grade

Featuring a 120 grade, the zirconia alumina mineral is designed for coarse stock removal and aggressive cutting. This grade delivers a faster cut rate compared to aluminum oxide, making it suitable for heavy grinding tasks.

The durable zirconia alumina fractures under pressure to expose fresh sharp points, maintaining cutting efficiency. It's ideal for deburring ferrous and non-ferrous metals with high-speed rotary tools.

Multi-Layer Abrasive Design

The cartridge roll uses a multi-layer design that continually reveals fresh abrasive material as it wears. This extends the tool’s life and keeps the cut consistent throughout use.

Wrapping multiple layers around the roll adds sturdiness and durability. The closed-coat construction ensures mineral grains cover 100 percent of the cloth backing for a smooth finish.

Convenient Pack Size Included

Each case contains 100 cartridge rolls, supporting large-scale or repeated projects without frequent reordering. This pack size is practical for workshops and industrial settings.

The arbor hole fits mandrel tool attachments, making it compatible with various high-speed tools. This feature enhances versatility and ease of use across different applications.
