40 Pack of 4.5 Grit 29 Flap Discs - Aluminum Oxide Abrasives for Grinding and Finishing

About this item

• High Grinding Efficiency - the surface of the sanding discs is equipped with a heat-resistant and anti-stick coating, and the high-strength aluminum oxide raw material which improve the grinding efficiency by 55% while ensuring the smooth surface of the material
• Thickened Glass Fiber Mesh Cover - The glass fiber mesh cover design of our grinding wheels is combined BASF (resin adhesive),it is more wear-resistant than an ordinary plastic mesh cover so that the service life is increased by 2 times. The blade knob is made of PE which will not break even at 13500 RPM
• Prevent Thermal Burns - In the grinding process, the temperature of general flap discs is too high, it is easy to burn the metal and make the metal discolor, which will reduce the hardness and toughness of the metal. The patented ratio of PEGATEC flap disc enhances heat dissipation and avoids thermal burns
• T29 15°Design, widely used - Our flap disc adopts T29 15° design, which is suitable for fine grinding of flat, curved, chamfered and concave-convex surfaces. The thick cloth base and high-tenacity cotton lining make the sanding discs more flexible, can be reached an excellent polishing effect
• Multi-Purpose Sanding Discs - Designed for grinding a variety of materials, suitable for metal or wood processing, concrete grinding or finishing, smoothing or finishing stone, removing rust, mixing welding, deburring, etc. Fits angle grinders with 7/8 spindles.
