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 Standard Abrasives Brand

The Standard Abrasives Zirconia Cartridge Roll, model 727347 CR-ST, is a reliable choice for metalworking tasks. This product is designed to meet the needs of professionals who require consistent performance and quality in their abrasive tools.

With over 50 years of experience supplying the metalworking industry, Standard Abrasives offers a product that combines durability and efficiency. The cartridge roll format ensures easy use with various high-speed tools for precise grinding and deburring.

Precise Size And Format

This cartridge roll measures 3/8 in x 1-1/2 in x 1/8 in, making it compact enough to reach tight spots. Its straight cylinder shape allows it to blend and deburr inside holes and on irregular surfaces with ease.

The 100 ea/Case pack size provides ample supply for ongoing projects. Its small size is perfect for working in grooves, slots, threads, and contoured surfaces, offering versatility in various applications.

Effective Zirconia Alumina Grade

The cartridge roll features a 120 grade zirconia alumina abrasive, ideal for coarse stock removal. This mineral fractures under pressure to continually expose fresh sharp points, delivering a faster cut rate than aluminum oxide.

This grade is well suited for high-speed grinding and deburring on both ferrous and non-ferrous metals. It handles heavy stock removal and edge breaking efficiently, making it a practical choice for tough jobs.

Durable Multi-Layer Design

The multi-layer construction of the Standard Abrasives cartridge roll ensures long-lasting performance. As the top layers wear down, fresh abrasive layers are revealed, maintaining a consistent cut throughout use.

This design also adds sturdiness and durability, while the resin bond anchors the mineral to the cloth backing. The closed-coat construction covers 100 percent of the backing for a smoother, more consistent finish.

Compatible Tool Attachment Options

The cartridge roll includes an arbor hole that fits mandrel tool attachments, allowing use with various high-speed rotary tools like die grinders or drills. This compatibility enhances its versatility for different tasks.

Mandrels should have a pilot length at least 1/2 inch shorter than the cartridge roll length to ensure proper fit. This feature supports efficient grinding and deburring in confined spaces and complex shapes.
