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.

Precise Size And Dimensions

Each cartridge roll measures 3/4 inch by 1-1/2 inches by 3/16 inch, designed to fit tight spaces and hard-to-reach areas. This straight cylindrical shape allows for smooth operation on irregular contours and inside holes.

The compact size helps operators blend, deburr, and polish with accuracy, especially on ferrous metals. Its dimensions make it ideal for detailed work where larger abrasives can't reach effectively.

Multi-Layer Abrasive Design

The multi-layer, multi-wear design enhances the cartridge roll’s longevity by exposing fresh abrasive points as the top layers wear down. This feature ensures a consistent cut and maintains sharpness over time.

Wrapped tightly into a roll, the abrasive material is secured with a resin bond on cloth backing, providing toughness and durability. This construction supports repeated use without losing effectiveness.

Grade And Cutting Performance

This cartridge roll comes in grade 120, offering a balance between aggressive cutting and smooth finishing. The aluminum oxide mineral cuts sharp and fragments under pressure to reveal new cutting edges.

Its abrasive properties make it ideal for blending, deburring, polishing, and removing machine tool marks on ferrous metals. The grade ensures it works well on various project needs requiring medium grit.

Format And Pack Convenience

The cartridge roll format fits mandrel tool attachments, allowing use with rotary tools like die grinders or drills. This compatibility makes it easy to work on angles, curves, and other challenging surfaces.

Sold in cases of 50, the pack size supports continuous workflow without frequent reordering. The straight roll design and pack quantity make it a practical choice for professionals handling multiple projects.
