PFERD Mounted flap wheel set, PFERD, 20 mm

PFERD TOOLS offers a wide selection of coated abrasive tools for working on different workpiece geometries and materials. They consist of a base, a base bond and a coating bond for the abrasive grain to adhere to. Depending on the grit size, coated abrasive tools can achieve a high stock removal rate or a very fine surface finish.
The available backing materials differ in properties such as tear strength, flexibility and wear. With the right base, the grinding tool is adapted to the requirements of the intended application: paper is used in the woodworking industry and in trade, e.g. among carpenters, painters and decorators, cloth is predominantly used for metalwork, and vulcanized fibre is highly wear-resistant and is used in various thicknesses predominantly for making fibre discs.
The set contains three mounted flap wheels in the aluminium oxide A type with a shank diameter of 6 mm in grit sizes 60, 80 and 120.
On mounted flap wheels, the flaps made of coated abrasive are arranged radially around the tool axis in a fan-type structure. Their flexibility enables them to adapt perfectly to the contours of the workpiece. The abrasive grain is embedded in the sturdy, flexible cloth backing material by means of a resinoid bond.
