7" x 7/8" Zirconia Resin Fibre Discs
Scale up your heavy-duty grinding operations with our 7" x 7/8" Zirconia Resin Fibre Discs. Designed for large-scale metal fabrication, these discs utilize a premium Zirconia Alumina grain bonded to a rugged vulcanized fibre backing. The 7-inch diameter provides a massive contact area, allowing you to cover more surface area in less time—making them the go-to choice for shipyards, structural steel shops, and industrial manufacturing.
The self-sharpening Zirconia grain thrives under the high pressure and high RPMs of 7" grinders, fracturing to reveal new sharp points that maintain a consistent cut rate throughout the life of the disc.
Product Features:
Industrial-Grade Zirconia Grain: Engineered for high-pressure applications, offering a faster cut and longer life than standard aluminum oxide on tough materials like stainless and carbon steel.
Heavy-Duty Vulcanized Fibre Backing: The ultra-rigid backing provides the stability required for 7" grinders, ensuring the disc can withstand aggressive stock removal without tearing.
Efficient Surface Coverage: The large 7" diameter significantly increases productivity by covering larger weld seams and surface areas more quickly than smaller discs.
Resin-over-Resin Bonding: A superior bond that locks the abrasive grain in place and resists the intense heat generated during heavy grinding, preventing premature grain shedding.
Available Grits:
24 - 36 Grit: Maximum aggression for leveling heavy weld beads, deep deburring, and rapid stock removal on large workpieces.
50 - 60 Grit: The "workhorse" grits for general-purpose grinding, heavy blending, and edge chamfering.
80 Grit: Ideal for cleaning scale, rust removal, and surface preparation on large metal plates.
100 - 120 Grit: The choice for finishing large surfaces and removing deep scratches before final coating.
Applications: Structural steel grinding, shipyard maintenance, heavy equipment repair, and aggressive weld removal on all ferrous and non-ferrous metals.
