FLAP DISCS Advantage : Bonded to extremely strong but durable fibreglass or plastic backing Fast ,aggressive action for high pressure grinding,high efficiency Blending and finishing all in one operation and will reduce process time,Saving grinding cost Maximum contact with work surface without loading Consistent grinding and finishing performance , reduce operator fatigue and increase machine life High elasticity, good self-sharpening, high grinding rate and low noise compared to depressed center grinding discs The 100 blades are mainly installed on hand-held electric tools for grinding and polishing welds, burrs, chamfers, surface rust removal and surface polishing of all kinds of metal and non-metal parts. The grinding and polishing process is completed at one time, and the operation is simple and fast. It has high elasticity, good self-sharpening, high grinding rate and low noise. It is used in various stainless steel and non-metal parts. The effect of grinding and polishing of carbon steel structural parts is excellent.
