37110 - 4.5 Inch 24 Grit Aluminum Oxide Resin Fiber Disc

Aggressive Stock Removal for Welders

For welders and fabricators requiring aggressive material removal, the Arc Abrasives 37110 4-1/2" x 7/8" Resin Fiber Disc is a go-to solution. With a coarse 24 grit Aluminum Oxide abrasive, this disc is specifically designed to tackle the toughest grinding challenges, such as leveling heavy weld beads, beveling plate edges, and removing deep surface imperfections. The sharp cutting action of the premium A/O grain bites into the metal immediately, allowing operators to remove material rapidly without generating excessive heat that could warp the workpiece.

Durability is key in welding environments, and this disc features a robust fiber backing that provides the necessary stiffness and support for high-pressure grinding. Unlike flap discs which cushion the cut, a resin fiber disc on a hard backing pad transfers maximum force to the work surface, making it superior for hogging out material. The resin bonding agent ensures that the abrasive grains remain fixed to the backing even under the high temperatures generated during aggressive grinding, preventing premature shelling and extending the life of the disc.

This 4-1/2 inch disc fits standard angle grinders with a 7/8 inch arbor, making it a universal consumable for most welding rigs. It is particularly effective on carbon steel and structural iron, where its tough grain structure resists dulling. Whether you are prepping a joint for welding or cleaning up a finished structure, the Arc Abrasives 37110 offers the reliability and bite required for heavy industrial use.

To maximize the life and performance of this disc, store it in a cool, dry place to prevent the fiber backing from absorbing moisture and curling. Always use a backing pad rated for the RPM of your grinder. This disc is an essential consumable for any welder's toolkit, providing the raw grinding power needed to prepare surfaces and finish heavy welds efficiently.
