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 Dimensions For Use

Each cartridge roll measures 1/2 inch by 2 inches by 3/16 inch, providing a compact size that fits well in tight spaces. This size allows operators to access hard-to-reach areas with ease during blending and polishing tasks.

The straight cylindrical shape of the roll helps it roll smoothly over irregular contours. This design supports detailed work on ferrous metals, making it ideal for finishing angles and curves.

Multi-Layer Abrasive Design

The cartridge roll features a multi-layer, multi-wear design that extends its lifespan. As the top layers wear down, fresh abrasive surfaces are exposed, maintaining a consistent cut throughout its use.

This layering also adds durability, with a resin bond securing the aluminum oxide mineral to the cloth backing. The closed-coat construction ensures full coverage for a smoother finish on your workpieces.

Versatile Grade Options Available

This product comes in a range of grades from 36 to 400, allowing you to select the right abrasive level for your project. The aluminum oxide mineral cuts sharp and fragments under pressure to reveal new cutting edges.

Such versatility means you can use these cartridge rolls for coarse grinding or fine polishing. They’re suitable for removing machine tool marks, flash, and for edge breaking on ferrous metals.

Compatible With Mandrel Tools

The cartridge roll includes an arbor hole that fits mandrel tool attachments, sold separately. This feature lets you attach the roll to rotary tools like die grinders or drills for efficient operation.

Using the mandrel with the 715219 CR-ST cartridge roll enables grinding and finishing in tight or angled spaces. This compatibility enhances the roll’s usefulness on irregular contours and inside holes.
