40 GRIT ZIRCONIA FLAP DISC, 4-1/2" x 7/8", 13,300 MAX RPM
Engineered for rapid material removal and a consistent finish, this 40-grit zirconia flap disc is a high-performance abrasive for grinding, blending, and finishing metal surfaces. The premium zirconia alumina grain provides an aggressive, cool cut and an extended service life on steel, stainless steel, and other ferrous metals. It is designed for use on standard 4-1/2" angle grinders.
- 40 Grit Zirconia Alumina Abrasive
- ANSI B7.1 Compliant
- Max Speed: 13,300 RPM
- Application: Grinding & Finishing Metals
This industrial-grade flap disc is constructed with premium zirconia alumina abrasive grains resin-bonded to a durable fiberglass backing plate. The 40-grit grain structure is designed for aggressive stock removal, weld grinding, and heavy deburring tasks. Zirconia alumina is a self-sharpening abrasive, meaning new, sharp cutting points are continuously exposed during use, resulting in a faster cut rate and longer life compared to standard aluminum oxide discs. The layered flap design allows the disc to grind and finish in a single step, reducing downtime.
Ideal for metal fabricators, welders, and MRO professionals in the Los Angeles area, this flap disc excels at tasks on carbon steel, stainless steel, and other heat-sensitive alloys. It is the perfect tool for cleaning up welds, removing rust or paint, chamfering edges, and surface blending. Its versatility makes it a staple consumable for manufacturing, construction, and general industrial maintenance. This disc provides consistent performance for both high-production environments and detailed finishing work.

Target Users
This flap disc is an essential tool for professional welders, metal fabricators, maintenance technicians, and construction workers who require efficient and reliable metal grinding and finishing solutions. It's designed for heavy use in industrial shops and field applications.
Finish Options
This is a consumable abrasive product and does not have a finish option. It is used to create a specific surface finish on a workpiece, with the 40-grit rating providing a coarse, rough finish suitable for initial grinding stages.
How to Measure
To ensure compatibility, specify the disc's diameter, arbor (center hole) size, and grit. The diameter must match your angle grinder's capacity (e.g., 4-1/2"), and the arbor size must match the grinder's spindle (e.g., 7/8"). Select the grit based on the application: lower numbers (like 40) are for aggressive material removal, while higher numbers are for smoother finishing.
Example: Product: Zirconia Flap Disc, Size: 4-1/2" x 7/8", Grit: 40, Quantity: 50
