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 Quality

With a pack count of 50 pieces per case, this cartridge roll ensures you have enough supply for multiple projects. The model CR-ST is designed specifically for straight cylindrical applications, making it a trusted choice for professionals.

Precise Dimensions For Use

Each cartridge roll measures 3/4 inch by 1 inch by 3/16 inch, providing a compact size that fits well in tight spaces. These dimensions allow the roll to reach irregular contours and hard-to-access areas with ease.

The straight cylindrical shape supports smooth operation on ferrous metals, helping users blend, deburr, and polish with precision. This size is ideal for detailed work where larger abrasives might not fit.

Multi-Layer Design Benefits

The multi-layer, multi-wear design of this aluminum oxide cartridge roll extends its lifespan by exposing fresh abrasive layers as the top ones wear away. This keeps the cut consistent and sharp over time.

Its resin bond securely anchors the abrasive mineral to the cloth backing, enhancing durability. This design ensures the roll withstands repeated use while maintaining effective cutting and polishing performance.

Versatile Grade Options

The cartridge roll comes in a grade of 40, suitable for fast cutting and polishing on ferrous metals. This grade balances aggressive material removal with a smooth finish, making it versatile for many applications.

Different grades are available to meet specific project needs, but the 40 grit in this model is ideal for edge breaking, flash removal, and blending on irregular surfaces and contours.

Format And Pack Count

This product is supplied as a cartridge roll format, which fits mandrel tool attachments for rotary tools like die grinders or drills. The format allows easy use on angles and curves that are difficult to reach.

Each case contains 50 cartridge rolls, ensuring ample quantity for ongoing work. The pack size supports both small and large projects, providing convenience and value for users.
