• Ideal for blending, deburring and polishing on ferrous metals
• Multi-layer, multi-wear design enhances abrasive longevity and helps produce a consistent cut
• Straight cylindrical shape enables operators to finish hard-to-reach areas
• Versatile range of minerals and grades are designed to meet specific project needs

Standard Abrasives Aluminum Oxide Cartridge Roll is ideal for fast cutting on irregular contours and other hard-to-reach areas on all ferrous metals.

Recommended Applications
​The multi-layered Standard Abrasives™ Aluminum Oxide Cartridge Roll exposes new abrasive cutting points throughout the life of the roll. Combining an aggressive cut with durability makes it great for polishing, edge breaking and removal of machine tool marks or flash. Its small size and shape enable it to blend, deburr and polish inside holes and diameters or on irregular surfaces and contours.The cartridge roll has an arbor hole to accommodate a mandrel tool attachment (sold separately). This mandrel attaches to a rotary tool such as a die grinder or drill and comes in different sizes to fit a variety of cartridge roll sizes. Together, the mandrel and cartridge roll enable the user to grind or finish hard-to-reach areas of a workpiece, such as angles and curves.

The Aluminum Oxide Cartridge Rolls come in a variety of sizes and grades, so it can be tailored to meet your project needs.Grades range from 36 to 400, producing a spectrum of finishes, from coarse to fine.It is made with aluminum oxide mineral, which cuts sharp and is friable – fragmenting under heat and pressure to reveal sharp cutting edges as it abrades the surface.The straight roll design is cylindrical, which helps it roll over irregular contours.

Benefits of a Multi-Layer Design
The multi-layer, multi-wear design of Standard Abrasives™ Aluminum Oxide Cartridge Roll keeps it cutting sharp and helps it withstand repeated wear. As top layers wear down over time, underlying layers expose fresh mineral, so you get a 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 you get a smoother, more consistent finish is achieved. Seemingly small, these cartridge rolls conquer big challenges when space gets tight.

Standard Abrasives Brand Model

The Standard Abrasives Aluminum Oxide Cartridge Roll, model 713444 CR-ST, offers reliable performance for various metalworking tasks. This product is designed to meet professional standards with its specific model and brand recognition.

Its straight cylindrical shape and aluminum oxide mineral make it suitable for blending, deburring, and polishing ferrous metals. The model CR-ST ensures consistent quality across applications.

Precise Size And Dimensions

This cartridge roll measures 3/4 inch by 1-1/2 inch by 1/8 inch, providing a compact size that fits well in tight or hard-to-reach areas. The straight format allows for easy maneuvering on irregular contours.

Its dimensions make it ideal for detailed work such as edge breaking and removal of machine tool marks. The small size supports polishing inside holes and diameters efficiently.

Grade And Abrasive Quality

The roll features an 80 grit grade, balancing aggressive cutting with smooth finishing. This grade is part of a versatile range designed to meet specific project needs from coarse to fine finishes.

Made with aluminum oxide mineral, the abrasive cuts sharp and fragments under pressure to reveal fresh edges. This ensures durability and consistent performance throughout the roll’s life.

Multi-Layer Design Benefits

The multi-layer, multi-wear design enhances the cartridge roll’s longevity by exposing new abrasive points as the top layers wear down. This keeps the cut consistent and sharp for extended use.

Wrapped tightly into a roll, the layers add sturdiness and durability. A resin bond anchors the mineral to the cloth backing, improving toughness and strength for demanding tasks.

Pack Count And Format

This product comes in a pack of 50 pieces per case, providing ample supply for ongoing projects. The cartridge roll format is compatible with mandrel tool attachments for rotary tools.

The arbor hole allows easy mounting on mandrels (sold separately), enabling use with die grinders or drills. This setup helps finish hard-to-reach angles and curves efficiently.
