• 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 Brand Model

The Standard Abrasives Aluminum Oxide Cartridge Roll, model 707620 CR-ST, offers reliable performance for various metalworking tasks. This product is designed to meet professional standards with consistent quality and durability.

Its model number 707620 and brand name ensure you get the exact cartridge roll needed for your projects. The CR-ST designation indicates the straight cylindrical shape, ideal for precision work.

Precise Dimensions And Size

This cartridge roll measures 1/4 inch by 1 inch by 1/8 inch, providing a compact size that fits tight spaces. The straight cylindrical shape allows it to reach hard-to-access areas with ease.

Its small dimensions make it perfect for blending, deburring, and polishing inside holes or on irregular contours. This size supports detailed finishing on ferrous metals.

Grade And Abrasive Quality

The roll features a 120 grade aluminum oxide abrasive, balancing aggressive cutting with smooth finishes. This grade is suitable for fast cutting and polishing on ferrous metals.

Aluminum oxide mineral is friable, meaning it fragments under pressure to expose fresh cutting edges. This keeps the abrasive sharp and effective throughout its use.

Multi-Layer Design Benefits

The multi-layer, multi-wear design extends the cartridge roll’s life by exposing new abrasive layers as the top ones wear down. This ensures a consistent cut and long-lasting performance.

Wrapped layers and a resin bond secure the mineral to the cloth backing, enhancing toughness. The closed-coat construction covers 100 percent of the backing for a smooth, even finish.

Pack Count And Format

This product comes in a pack of 100 cartridge rolls per case, providing ample supply for ongoing projects. The cartridge roll format fits mandrel tool attachments for versatile use.

The arbor hole accommodates mandrels sold separately, enabling attachment to rotary tools like die grinders or drills. This setup helps finish hard-to-reach angles and curves efficiently.
