• Arbor hole accommodates mandrel tool attachment, so abrasive may be used with various tools
• Ideal for blending, deburring and polishing on ferrous metals
• Multi-layer, multi-wear design enhances abrasive longevity and helps produce a consistent cut
• 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 702513, CR-ST, 40, offers reliable performance for various metalworking tasks. This product is designed specifically for fast cutting on irregular contours and hard-to-reach areas.

Its aluminum oxide mineral composition ensures sharp cutting edges that fragment under heat and pressure, maintaining effectiveness throughout use. The CR-ST format supports consistent results on ferrous metals.

Precise Size And Dimensions

This cartridge roll measures 3/8 inch by 1-1/2 inch by 1/8 inch, making it compact and easy to maneuver in tight spaces. The straight cylindrical shape allows operators to reach angles and curves that are difficult with other abrasives.

Its small size is ideal for blending, deburring, and polishing inside holes or on irregular surfaces, providing versatility for detailed finishing work.

Multi-Layer Abrasive Design

The multi-layer, multi-wear design enhances the cartridge roll’s longevity by exposing fresh abrasive cutting points as the top layers wear down. This keeps the cut consistent part after part.

Wrapped layers around the roll add sturdiness and durability, while a resin bond secures the mineral to the cloth backing. This construction supports a smooth, consistent finish on all ferrous metals.

Versatile Grades And Uses

The cartridge roll is available in grade 40, suitable for a range of applications from coarse to fine finishes. This grade is effective for polishing, edge breaking, and removing machine tool marks or flash.

Its versatility extends to blending and deburring tasks on ferrous metals, making it a practical choice for many project needs requiring precision and control.

Pack Count And Compatibility

Each case contains 100 cartridge rolls, providing ample supply for ongoing projects. The arbor hole accommodates mandrel tool attachments, sold separately, to fit various rotary tools like die grinders or drills.

This compatibility allows users to attach the roll securely and work efficiently on hard-to-reach areas, enhancing productivity and ease of use in different setups.
