• 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 709600 CR-ST, offers reliable performance for various metal finishing tasks. This pack includes 100 pieces, making it suitable for extended use or multiple projects.

Each cartridge roll is designed with a straight cylindrical shape, measuring 3/8 in x 1-1/2 in x 1/8 in, which helps operators reach tight or irregular areas with ease. The model CR-ST ensures compatibility with many tools.

Durable Multi-Layer Design

This cartridge roll features a multi-layer, multi-wear design that extends abrasive life by exposing fresh cutting points as the top layers wear down. This design helps maintain a consistent cut throughout the roll's use.

The layers are securely bonded with resin to a cloth backing, enhancing toughness and strength. This construction supports durability even during demanding tasks like deburring and polishing.

Precise Dimensions Included

Each cartridge roll measures 3/8 inch by 1-1/2 inch by 1/8 inch, providing a compact size that fits well in tight spaces. The straight shape allows it to roll smoothly over irregular contours for effective finishing.

These dimensions make the roll ideal for blending, edge breaking, and polishing inside holes or on curved surfaces, especially on ferrous metals where precision is key.

Versatile Abrasive Grades

The product comes in a range of grades from 36 to 400, allowing users to select the right level of abrasiveness for their specific project needs. This variety supports finishes from coarse to fine.

Using aluminum oxide mineral, the rolls cut sharp and fragment under pressure to reveal new edges, making them effective for fast cutting on irregular contours and hard-to-reach areas.

Pack Size And Format

This package contains 100 cartridge rolls, providing ample supply for continuous work or multiple applications. The format is a cartridge roll designed for use with mandrel tool attachments.

The arbor hole in each roll fits mandrels that attach to rotary tools like die grinders or drills, enabling grinding and finishing in difficult spots such as angles and curves.
