4-1/2" x 7/8" Ceramic Resin Fibre Discs
Experience ultimate cutting power with our 4-1/2" x 7/8" Ceramic Resin Fibre Discs. These discs represent the highest tier of abrasive technology, featuring a micro-crystalline Ceramic grain that is significantly harder and tougher than Zirconia or Aluminum Oxide. Designed for use with a 4-1/2" right-angle grinder and a high-quality backup pad, they excel in high-pressure environments where speed and heat management are critical.
The self-sharpening Ceramic grain breaks down at a controlled rate, consistently providing a fresh, sharp cutting surface. This ensures the fastest possible material removal and an incredibly long service life, even on the hardest alloys.
Product Features:
Top-Tier Ceramic Grain: Engineered for maximum aggression and efficiency. It requires less operator pressure to cut through hardened steel and high-nickel alloys.
Integrated Grinding Aid: These discs are treated with a specialized cooling agent (size coat) that reduces friction and heat buildup, effectively preventing "blueing" or heat tinting on stainless steel.
Heavy-Duty Vulcanized Fibre Backing: A rigid, industrial-strength foundation that provides the stability needed for high-torque grinding applications.
Resin-over-Resin Bond: A superior bonding system that locks the ceramic grains in place, resisting moisture and heat to prevent grain shedding during intense use.
Available Grits:
24 - 36 Grit: Extremely aggressive for rapid stock removal, heavy weld grinding, and leveling thick material.
50 - 60 Grit: The professional choice for fast blending, edge breaking, and high-productivity grinding.
80 Grit: Ideal for surface refinement, removing deep scratches, and preparing metal for final coatings.
100 - 120 Grit: The ultimate choice for high-end finishing and creating a uniform surface on premium workpieces.
