Features Similar to 577F Extra high cutting power, high performance Runs cool for reliable use on heat-sensitive metals and stainless steel Durability in high-production operations For heavy stock removal and high pressure grinding Zirconia Abrasive with Grinding Aid Zirconia abrasive features harp self-sharpening. A grinding aid is incorporated in the belt to provide an aiding cutting, reduce friction, protect the material integrity. Thus this Zirconia sanding belt delivers MUCH MORE CUTTING POWER, cut faster and perform well during heavy stock removal operations than that of aluminum oxide, conventional zirconia alumina and silicon carbide. Special Closed Top Coat Special closed top coat not only helps extend longer lifespan and improve grinding efficiency, but also reduces running temperatures to runs cool for reliable use on heat-sensitive alloys such as stainless steel, nickel alloys and cobalt alloys. German Technology, Heavy Duty, Y-Weight Polyester Backing Supports the zirconia grain resisting slipping and tearing during high-production operations, helping to deliver a consistent aggressive cutting action and extend lifespan. Much heavier duty than X-weight cloth backing! Resin Over Resin Bond The abrasive is firmly bonded to the backing with double resin to maintain durability under high heat and pressure. Strong Blue Butt Joint Enhances the robustness of the interface, resisting dehiscing during heavy stock removal operations. Blue butt joint also features more strong than red ones Quality Grade: Similar to 577F For Use On: Stainless Steel, Nickel Alloys, Cobalt Alloys and Cast Iron Industrial: Aerospace, AOEM, Metalworking, Primary Metal Specifications Abrasive Color: Blue Back Color: Black Grade: Extra Coarse, Coarse, Medium Abrasive Material: Zirconia with Grinding Aid Coat Type: Closed Top Coat Bond: Resin Over Resin Adhesive Backing Material: Polyester Cloth Backing Weight: Y-Weight Joint: Blue Butt Joint (Much Stronger than Red Butt Joint) Application: Deburring, Finishing, Grinding, Surface Preparation For Use On: Stainless Steel, Nickel Alloys, Cobalt Alloys and Cast Iron Industrial: Aerospace, AOEM, Metalworking, Primary Metal Market: Maritime, Facilities Management Belt Size: 4 x 24 inch （100 x 610mm) Grit Size: 120 Grit Quantity: 3 Pack Shipped same-day from Houston via USPS First Class, USPS-Priority, UPS-Surepost or UPS Ground.
