4-1/2" x 7/8" Zirconia Resin Fibre Discs
Maximize your grinding efficiency with our industrial-grade 4-1/2" x 7/8" Zirconia Resin Fibre Discs. Engineered for aggressive material removal, these discs feature premium Zirconia Alumina grain bonded to a heavy-duty vulcanized fibre backing. Designed for use with a right-angle grinder and a backup pad, they provide the durability needed for high-pressure applications on stainless steel, carbon steel, and other tough alloys.
The self-sharpening grain continuously fractures to expose fresh cutting edges, ensuring a fast, consistent cut rate that far outlasts standard aluminum oxide discs.
Product Features:
High-Performance Zirconia Grain: Specifically designed for "cool-cutting" to prevent heat discoloration and warping on heat-sensitive metals like stainless steel.
Heavy-Duty Vulcanized Fibre Backing: Provides a rigid and stable foundation that resists tearing and ensures maximum pressure is transferred to the workpiece.
Resin-over-Resin Bond: A high-strength bonding system that secures the abrasive grain firmly, resisting heat and moisture for an extended disc life.
Universal Fit: The 7/8" arbor hole is compatible with standard 4-1/2" angle grinders, making it a versatile addition to any fabrication shop.
Available Grits:
24 - 36 Grit: Best for extreme stock removal, heavy weld grinding, and rough deburring.
50 - 60 Grit: Ideal for general-purpose grinding, leveling welds, and edge chamfering.
80 Grit: Perfect for blending, cleaning rust or scale, and surface preparation.
100 - 120 Grit: The choice for fine finishing, removing scratches, and prepping for paint or polish.
