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.

Standard Abrasives Model

The Standard Abrasives Zirconia Cartridge Roll, model 727339 CR-ST, offers reliable performance for grinding and deburring tasks. This product is designed to meet the needs of metalworking professionals who require precision and durability.

Its exact model number 727339 and brand name Standard Abrasives ensure you get a trusted product with consistent quality. The CR-ST designation indicates the cartridge roll format, which is easy to use with compatible tools.

Precise Size And Dimensions

This cartridge roll measures 1/4 inch by 1-1/2 inch by 1/8 inch, making it compact and ideal for tight spaces. The small size allows operators to reach grooves, slots, and irregular surfaces with ease during high-speed grinding.

Its dimensions support detailed work on machined parts and contours, helping to blend and deburr inside holes and diameters. This size is perfect for applications requiring accuracy in confined areas.

Durable Zirconia Alumina Grade

The product features an 80-grade zirconia alumina abrasive, known for its toughness and long-lasting performance. This coarse grade is excellent for heavy stock removal and aggressive cutting on ferrous and non-ferrous metals.

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

Multi-Layer Roll Format

The cartridge roll format uses a multi-layer design that continually reveals fresh abrasive material as the top layers wear down. This ensures consistent cutting performance throughout the life of the roll.

Wrapping multiple layers around the roll adds sturdiness and durability. The straight roll shape, as specified in the title, is effective for reaching curves on stamped or rounded parts.

Pack Count And Compatibility

This product comes in a pack of 100 cartridge rolls per case, providing ample supply for industrial or workshop use. The pack size supports ongoing projects without frequent reordering.

The arbor hole in each roll fits mandrel tool attachments, allowing use with various high-speed rotary tools like die grinders or drills. This compatibility enhances versatility across different applications.
