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 708530 CR-ST, offers reliable performance for various metalworking tasks. This pack includes 100 pieces, ensuring you have enough rolls for multiple projects or extended use.

Each cartridge roll is designed with the brand's quality standards, making it suitable for professionals who need consistent results. The model number CR-ST identifies the straight cylindrical shape, which helps reach tight or irregular spaces.

Precise Dimensions Matter

These cartridge rolls measure 1/2 inch by 1-1/2 inch by 1/8 inch, providing a compact size that fits well in small or hard-to-reach areas. The straight shape allows for smooth finishing on contours and inside holes.

The specific dimensions make these rolls ideal for blending, deburring, and polishing tasks on ferrous metals. Their size also supports detailed work where larger abrasives would be impractical.

Multi-Layer Abrasive Design

The multi-layer, multi-wear design enhances the cartridge roll's longevity by exposing fresh abrasive surfaces as the top layers wear down. This ensures a consistent cut throughout the life of each roll.

Wrapped tightly in layers, the roll maintains durability and toughness. The resin bond secures the aluminum oxide mineral to the cloth backing, providing strength and a smooth finish every time.

Versatile Aluminum Oxide Grade

Made with aluminum oxide mineral, these cartridge rolls cut sharp and fragment under heat and pressure to reveal new cutting edges. This makes them effective for fast cutting on irregular contours and hard-to-reach areas.

The rolls come in a range of grades from 36 to 400, allowing you to select the right finish from coarse to fine. This versatility suits various project needs, from polishing to edge breaking and flash removal.

Convenient Pack And Format

The cartridge rolls come in a pack of 100, providing ample supply for ongoing or large-scale projects. Their straight cylindrical format fits mandrel tool attachments, expanding their usability with rotary tools.

This format allows operators to finish inside holes, diameters, and irregular surfaces with ease. The arbor hole accommodates mandrels (sold separately), making these rolls compatible with die grinders or drills.
