• 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 711570 CR-ST, offers reliable performance for various metal finishing tasks. This product is designed to meet professional standards with consistent quality and durability.

Its straight cylindrical shape and aluminum oxide mineral make it ideal for blending, deburring, and polishing ferrous metals. The model CR-ST ensures compatibility with many rotary tools for versatile use.

Precise Dimensions And Size

This cartridge roll measures 3/4 inch by 2 inches by 3/16 inch, providing a compact size that fits well in tight or hard-to-reach areas. The straight format allows operators to work on irregular contours with ease.

Its small size is perfect for detailed work such as polishing inside holes or on curved surfaces. The dimensions support efficient handling and precise finishing on various metal parts.

Grade And Abrasive Quality

The cartridge roll comes in a 60 grit grade, balancing aggressive cutting with smooth finishing. This grade is suitable for removing machine tool marks and flash while maintaining surface quality.

Aluminum oxide mineral is friable, meaning it breaks down under pressure to expose fresh cutting edges. This ensures the abrasive stays sharp and effective throughout its use.

Multi-Layer Design Benefits

The multi-layer, multi-wear design extends the life of the cartridge roll by exposing new abrasive layers as the top ones wear down. This feature maintains a consistent cut and reduces the need for frequent replacements.

Wrapped layers and a resin bond enhance durability and toughness, while the closed-coat construction covers 100 percent of the cloth backing. This results in a smoother finish and reliable performance.

Pack Count And Format

This product is sold in a pack of 25 cartridge rolls per case, making it convenient for bulk use in workshops or production environments. The cartridge roll format works with mandrel tool attachments for easy installation.

The arbor hole accommodates mandrels (sold separately), allowing attachment to rotary tools like die grinders or drills. This setup is ideal for grinding and finishing hard-to-reach angles and curves.
