4-½” GRINDING DISC, 4-½” X ¼” X ⅞”, RPM:13,300
Engineered for aggressive material removal and weld preparation, this 4-1/2" grinding disc offers high performance and safety. Its robust, fiberglass-reinforced construction ensures durability for demanding fabrication, MRO, and construction projects in the Los Angeles area.
- ANSI B7.1 Compliant
- 13,300
- Aluminum Oxide
- Fiberglass Mesh
This industrial-grade grinding disc is constructed from premium aluminum oxide abrasive grains bonded with a specialized resin and reinforced with high-tensile fiberglass mesh. This composite design ensures structural integrity at high rotational speeds up to 13,300 RPM, providing both aggressive grinding action and enhanced operator safety. The 1/4-inch thickness is ideal for heavy stock removal, weld blending, and edge chamfering on steel, iron, and other ferrous metals. Each disc is engineered to comply with ANSI B7.1 safety standards for abrasive wheels, making it a reliable choice for professional fabrication environments.
Designed for use with angle grinders, this 4-1/2" disc is an essential consumable for metalworkers, welders, and maintenance professionals. It excels at tasks such as smoothing weld beads, deburring cut edges, preparing surfaces for welding, and removing rust or scale. Its versatility makes it suitable for MRO (Maintenance, Repair, and Operations) tasks in industrial plants, as well as for new fabrication in structural steel shops, ornamental ironworks, and general construction. It provides a fast, efficient solution for shaping and finishing metal components.

Target Users
This grinding disc is an indispensable tool for professional welders, fabricators, metalworkers, and maintenance technicians requiring reliable, high-speed material removal for industrial projects.
Finish Options
Grinding discs are consumable tools and are not offered with specific finish options. The working surface consists of the specified abrasive material (e.g., aluminum oxide) designed for material removal. Different grit sizes can be selected to achieve coarser or finer surface profiles.
How to Measure
To ensure compatibility and safety, specify grinding discs using three key dimensions: Diameter x Thickness x Arbor Hole Size. The maximum RPM rating must meet or exceed the RPM rating of your angle grinder.
Example: 4-1/2" (Diameter) x 1/4" (Thickness) x 7/8" (Arbor), 13,300 Max RPM.
Order Checklist
- Disc Diameter, Thickness, and Arbor Size
