SALI 5 Pack Curved Flap Discs 4 1/2inch for Angle Grinder Sanding Disc 40 Grit Radial Zirconia Alumina Grinding Wheel High Density Abrasive Corner Flap Disc High Performance Edge Grinding - SALITools, O06MBL01

• Unique Design: This 4.5 inch curved flap disc (corner edge flap disc) is different from the traditional T27/T29 flap disc, the radial structure shape allows precise grinding of fillet welds and repair applications. The R angle of the 4-1/2inch inside corner flap disc can not only be ground on flat and curved surfaces, but also in difficult-to-grind locations such as welds. Wide Range of Use: 60 grit corner edge flap disc flapper wheel are the best choice for power cutting and can be used for contour and edge work, and their angled flaps provide greater surface contact. Mold repair of iron and non-ferrous metals, stainless steel plates, angle steel, stone and plastics, as well as grinding of welding seams, weld marks, and burrs of stamping parts. Efficient & Durable: The sand distribution of the curved flap discs welding grinding disc is even and full, with stronger wear resistance and not easy to drop sand. The Radial Shape grinding wheel has the characteristics of high elasticity, good self-sharpening, high grinding rate, good heat dissipation, low noise and long service life. High Cost Performance:Zirconia Angle Grinder Sanding Disc inside corner grinding wheel allows a continuous supply of the sharpest cutting edges and provides the fastest cut as well as the best utilization of the entire grit for the longest life. Light and Durable:The fiberglass backing plate helps absorb vibrations, consumes during use, and won't get dirty. Lightweight, durable, and forms a strong bond with adhesives, won't contaminate the workpiece.
