The RUBBER type is specifically designed for universal use on soft materials such as rubber, plastic, and wood. Applications include removing burrs on plastic injection-molded parts, trimming rubber molded parts and polyurethane (PUR) molded parts, grinding wooden cores and wooden shapes in model construction workshops, and roughing various adhesive joints (e.g. for repairs on conveyor belts and tires). The cylindrical shape is ideal for grinding radii and contours, and for deburring work.
