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 Model

The Standard Abrasives Aluminum Oxide Cartridge Roll, model 713369 CR-ST, offers reliable performance for various metal finishing tasks. This cartridge roll is designed to fit mandrel tool attachments, making it compatible with many rotary tools.

Precise Size And Dimensions

Each cartridge roll measures 1/2 inch by 2 inches by 3/16 inch, offering a compact size that fits well in small or hard-to-reach areas. This size is ideal for detailed blending, deburring, and polishing on ferrous metals.

The straight roll design helps it roll smoothly over uneven surfaces, making it easier to maintain consistent contact and finish. Its dimensions also ensure it works well with mandrels designed for this size range.

Durable Multi-Layer Design

The multi-layer, multi-wear construction extends the life of the cartridge roll by exposing fresh abrasive layers as the top ones wear down. This design keeps the cut consistent and sharp throughout the roll’s use.

Wrapped tightly with a resin bond, the aluminum oxide mineral is firmly anchored to the cloth backing. This sturdy build helps the roll withstand repeated wear while maintaining effective cutting and polishing.

Versatile Grade Options

The cartridge roll comes in a 60 grit grade, which balances aggressive cutting with smooth finishing. This grade is well-suited for removing machine tool marks, polishing edges, and blending surfaces on ferrous metals.

Grades range from coarse to fine, allowing users to select the right abrasive for their specific project needs. The aluminum oxide mineral cuts sharp and fragments under pressure to reveal fresh cutting edges.

Effective Format And Pack

This product is supplied in a roll format, which is easy to handle and use with mandrel attachments. The straight cartridge roll shape is designed for efficient grinding and finishing in tight or angled spaces.

Each case contains 50 cartridge rolls, making it convenient for workshops or professionals who require a steady supply. The format and pack size support both small jobs and larger production runs.
