What grit level is available with this cartridge roll?

The Standard Abrasives™ Aluminum Oxide Precision Cartridge Roll Model R (formerly Kay Rolls) is a multi-layered abrasive tool that is perfect for high tolerance and precision grinding. Its self-trimming capability exposes new abrasive cutting points throughout the life of the roll, while the secure bond of the roll to the drive stem eliminates loosening and vibration.
This cartridge roll is great for polishing, edge breaking, and removing 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 mounted stem attaches to a high-speed rotary tool such as a die grinder or drill for smooth, controlled high-speed grinding.
Running a Cartridge Roll on a High-Speed ToolThe Model R cartridge roll has a rear-mounted 1/4˝ stem that makes the entire roll usable for increased productivity and reduced downtime. This stem attaches to a rotary tool such as a die grinder or drill for smooth, controlled high-speed grinding, and negates the need for a separate mandrel attachment.
Aluminum Oxide Cartridges Offer a Broad Range of OptionsStandard Abrasives™ offers Aluminum Oxide Precision Cartridge Rolls in a wide variety of sizes and grades to suit particular contours and different applications. For Model R, grades range from 40-320, producing a spectrum of finishes from coarse to fine. Aluminum oxide mineral cuts sharp and is friable – fragmenting under heat and pressure to reveal sharp cutting edges as it abrades the surface.
Benefits of a Multi-Layer DesignThe multi-layer, multi-wear design of a Standard Abrasives™ Cartridge Roll keeps it cutting sharp and helps it withstand repeated wear. As top layers wear down with use, underlying layers expose fresh mineral, so you get a continuous and 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 that a smoother, more consistent finish is achieved.
