Flap Disc Zirconium 125mm 40 Grit Flat

Flap Sanding Disc Grit: 40 Flaps: 72 Diameter: Ø125mm Arbor: Ø22.22mm Abrasive material: Zirconium This 125mm Zirconium Flap Disc is engineered for high-intensity industrial applications requiring rapid material removal and exceptional durability. Featuring a 40-grit zirconium alumina grain, this disc is significantly tougher than standard aluminium oxide, offering a faster cut rate and a longer service life when working with stainless steel, structural steel, and other hard metals. The flat profile design is optimized for precision grinding on flat surfaces and outside edges, allowing the operator to maintain maximum contact and control for a consistent, level finish. Constructed with a heavy-duty fiberglass backing, the disc provides a rigid and stable foundation that effectively absorbs operational vibrations and resists high-pressure wear. This reinforced structure ensures safety and efficiency during aggressive tasks such as heavy weld grinding, scale removal, and edge chamfering. The self-sharpening zirconium grains continuously fracture to expose fresh, sharp edges, ensuring the disc maintains its cutting power throughout its entire lifespan, even under extreme heat and friction. Application: Weld seam removal & finishing Deburring & surface preparation Material removal prior to coating Blending/grinding on flat and contoured metal surfaces Primary Use: Steel. Secondary Use: Wood & plastic. Manufacturing Automotive Construction DIY
