| DESCRIPTION: | Black Hawk Quick Change 6AM Unitized Discs are designed for effortless and efficient fdeburring, blending, and cleaning in a compact size; ideal for work in confined spaces. Unitized wheels feature compressed, and cured layers of non-woven nylon fibers impregnated with abrasive grains. The structure of these unitized wheels allows for bi-directional use (they can be run in either direction), reduced loading, and minimal heat buildup which extends the life of the disc and protects the work piece. These unitized discs are less conforming than other surface preparation wheels to ensure a more consistent and uniform finish. Each quick-change unitized disc is constructed with a Type R, Roloc attachment to reduce changing time (Roloc TR, Lockit, and Powerlock III compatible.) decreasing work down time. These BHA Unitized quick change discs are 6 A M meaning they are high density (6), use the abrasive grain aluminum oxide (A), and have an abrasive grain grade of medium (M). High density wheels offer superior edge retention which helps maintain consistent shape and cutting action even during heavy duty applications. High density discs last longer, provide added rigidity and should be used for more difficult blending and deburring jobs. Aluminum Oxide is the most commonly used abrasive and is best suited for general-purpose deburring and blending, it is tough, economical and fracture-resistant. AOX is commonly used on ferrous alloys and high-tensile materials such as: Soft Steels, Low Carbon Steels, Tool Steels & Other Ferrous Materials. Medium grades are ideal for light deburring, cleaning and blending. The combination of these characteristics makes these discs the perfect option for more aggressive cleaning scale / oxidation, removing edges as well as blending marks, and eliminating deeper scratches. |
