Tackling Nooks and Crannies The multi-layered Standard Abrasives™ Ceramic Cartridge Roll is cylindrical in shape, which helps it roll centrifugally over irregular edges and contours. We engineer the product by rolling abrasive material into a tight cylinder resembling a small, circular barrel. This shape helps the abrasive work within nooks and crannies of the part. Cartridge rolls have an arbor hole to accommodate a mandrel tool attachment (sold separately), which attaches to a rotary tool such as a die grinder or drill. Mandrels come in different sizes to fit a variety of cartridge rolls. Together, the mandrel and roll enable the user to grind or finish hard-to-reach areas of a workpiece, such as angles and curves. Built for Strength Abrasive material on Standard Abrasives™ Ceramic Cartridge Roll is comprised of ceramic mineral, a cotton backing and cured resin. Ceramic mineral is created by heating alumina and other compounds, almost to the point of liquefaction. As the grain cools, it becomes extremely durable and tough. Ceramic’s cool cutting action reduces the risk for loading and part discoloration that may result from heat. These are some of the reasons it’s a good match for heat-sensitive metals like stainless steel and high nickel alloys. Given the strength and durability of the mineral, this abrasive is a good match for blending, deburring and polishing. It will stand up to the heavy pressure that often results from applications like edge breaking and flash removal. Additionally, our cartridge roll comes in a variety of sizes and grades, so you can find the one that's best suited to your project needs. Benefits of a Multi-Layer Design The multi-layer, multi-wear design of Standard Abrasives™ Ceramic Cartridge Roll prolongs abrasive service life and helps it withstand wear and tear. As the top abrasive layer wears down over time, underlying layers are exposed. The even breakdown reveals fresh mineral, so you get a consistent cut – part after part.Seemingly small, these cartridge rolls conquer big challenges when space is tight.
