• 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 Model

The Standard Abrasives Aluminum Oxide Cartridge Roll, model 708564 CR-ST, offers reliable performance for various metalworking tasks. This specific model is designed to meet the demands of professionals needing consistent abrasive results.

Its straight cylindrical shape and aluminum oxide mineral make it suitable for blending, deburring, and polishing on ferrous metals. The CR-ST designation ensures you get the exact product engineered for these applications.

Precise Size And Dimensions

This cartridge roll measures 1/2 inch by 2 inches by 1/8 inch, providing a compact size that fits tight spaces. The dimensions allow it to reach hard-to-access areas where larger abrasives might not work effectively.

Its straight shape helps operators finish irregular contours and inside holes, making it ideal for detailed work on metal surfaces. The size supports versatility in various grinding and polishing tasks.

Grade And Abrasive Quality

The product comes in grade 80, which balances cutting speed and finish quality. This grade is effective for fast cutting on ferrous metals while maintaining a smooth surface after use.

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

Multi-Layer Roll Design

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 ensures a consistent cut and durability over time.

Wrapping multiple layers into a roll adds sturdiness, while the resin bond secures the mineral firmly to the cloth backing. This construction supports repeated use without losing effectiveness.

Pack Count And Format

This product is sold in a pack of 50 cartridge rolls per case, making it convenient for bulk use and reducing the need for frequent reordering. The cartridge roll format fits mandrel tool attachments for rotary tools.

The arbor hole allows easy attachment to die grinders or drills, enabling users to work on angles and curves. This format supports efficient finishing in hard-to-reach areas with the right tool setup.
