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 Quality

The Standard Abrasives Zirconia Cartridge Roll, model 727348 CR-ST, is a reliable choice for metalworking tasks. This product carries the trusted Standard Abrasives brand known for over 50 years of quality in coated and bonded abrasives.

Its design supports high performance in industrial applications, making it a dependable option for professionals who need consistent results. The pack contains 100 pieces, ensuring you have enough rolls for multiple projects.

Precise Size And Format

This cartridge roll measures 1/2 in x 1-1/2 in x 1/8 in, providing a compact size that fits tight spaces. The straight format allows it to work effectively on curves and rounded parts, making it versatile for various shapes.

Its small dimensions enable operators to reach grooves, slots, and contoured surfaces easily. The roll’s shape is ideal for blending and deburring inside holes or irregular surfaces on machined parts.

Effective Coarse Grade Performance

Rated at 120 grit, this cartridge roll is designed for coarse applications, perfect for heavy stock removal. The zirconia alumina mineral cuts faster than aluminum oxide, making it suitable for grinding and deburring ferrous and non-ferrous metals.

Its aggressive cut helps break edges and remove machine tool marks or flash, delivering a smooth finish on metal surfaces. This grade ensures durability even under high pressure and frequent use.

Durable Multi-Layer Design

The roll features a multi-layer construction that continually reveals fresh abrasive material as it wears. This design extends the life of each cartridge roll, maintaining sharpness and cutting ability over time.

Wrapped layers add sturdiness and resilience, while the resin bond secures the mineral to the cloth backing. The closed-coat construction ensures a consistent finish by covering 100 percent of the backing with abrasive grains.

Compatible Mandrel Attachment Use

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 feature enhances its versatility in different grinding setups.

Mandrels should have a pilot length at least 1/2 inch shorter than the roll length to ensure proper fit and function. This compatibility makes the 727348 CR-ST model easy to integrate into existing tool systems.
