• 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 707336 CR-ST, offers reliable performance for various metalworking tasks. This product is designed to meet professional standards with consistent quality and durability.

Its aluminum oxide mineral composition ensures sharp cutting edges, making it ideal for blending, deburring, and polishing ferrous metals. The cartridge roll format fits many applications requiring precision and control.

Precise Dimensions And Size

This cartridge roll measures 3/8 inch by 1-1/2 inch by 1/8 inch, providing a compact and easy-to-handle abrasive tool. Its straight cylindrical shape allows users to reach tight or irregular contours with ease.

The size is perfect for finishing hard-to-reach areas, such as inside holes or on curved surfaces. This makes it a versatile choice for detailed metal finishing tasks.

Multi-Layer Abrasive Design

The multi-layer, multi-wear design extends the life of the cartridge roll by exposing fresh abrasive points as the top layers wear down. This ensures a consistent cut throughout the roll’s use.

Wrapped layers and a resin bond securely anchor the abrasive mineral to the cloth backing, enhancing toughness and durability. This design helps maintain performance even with repeated use.

Grade And Cut Quality

The cartridge roll is available in grade 120, balancing aggressive cutting with smooth finishing. This grade is suitable for polishing, edge breaking, and removing machine tool marks or flash.

Its aluminum oxide mineral cuts sharp and fragments under heat and pressure, revealing new cutting edges. This keeps the abrasive effective for a variety of metalworking projects.

Pack Count And Format

This product comes in a pack of 100 cartridge rolls, making it convenient for bulk use or long-term projects. The roll format fits mandrel tool attachments for use with rotary tools like die grinders or drills.

The arbor hole design allows easy attachment to mandrels (sold separately), enabling grinding and finishing in tight or angled spaces. This format supports efficient work on complex shapes.
