【Great Performance】 4.5-inch discs with industrial-grade aluminum oxide offer faster grinding via heat-resistant anti-stick coatings and resin-bonded durability. Featuring uniform particles, anti-clog performance, and smooth finish, they provide cost-effective solutions for users 【Standard Specifications】 Each disc measures at a 4-1/2-inch diameter with a 7/8-inch arbor size, making it compatible with most 4.5”Angle grinders with a speed of up to 13300 RPM 【High Grinding Power】 The reinforced fiberglass backing plate, with its robust resin-fiber structure, enhances control and minimizes hand fatigue during prolonged use, enabling precise edge work on welded seams and uneven profiles while absorbing vibrations without smearing or polluting the workpiece 【Bevel Type 29】 When working, the angle between the T29 grinding wheel and the grinding surface is 15°to 25°. These bevel type 29 discs are angled to be more effective for contours, edge and weld blending, and radius grinding 【Wide Application】These flap discs are perfect for universal grinding, rust removal, beveling, welding, blending, deburring, cleaning, and widely used for ferrous metals, stainless steel, non-ferrous metals, wood or plastics
