Norton 05539510701 Fiber Disc 9.125 in 36 Grit Merit FX370 25pk

Product Description

The NORTON 05539510701 is an aluminum oxide fiber disc engineered for aggressive material removal on metal surfaces. Built on the Merit FX370 fiber backing, this disc delivers consistent cut rate and durability under high-pressure grinding applications. Measuring 9.125 inches in diameter with a 0.875-inch arbor hole, the 36-grit designation makes it well suited for stock removal, weld blending, and surface preparation work where coarse cutting action is required. Each pack contains 25 discs, supporting sustained production use without frequent reorder. Angle grinder operators and fabricators working in metal shops, pipe yards, and structural steel environments will find this disc a reliable workhorse for heavy-duty tasks.

This fiber disc is used in industrial and commercial fabrication settings where rapid material removal from steel, stainless steel, and other ferrous metals is the primary objective. Typical applications include weld seam grinding, edge deburring, and surface conditioning prior to coating or inspection. The 9.125-inch diameter fits larger angle grinders and right-angle grinders common in structural, shipbuilding, and heavy fabrication environments. The coarse 36-grit cut rate reduces time spent on initial stock removal passes, making it practical for high-volume production workflows.

Key Features

• Aluminum oxide abrasive grain provides aggressive, consistent cut on ferrous metals
• Merit FX370 fiber backing resists flex fatigue during high-pressure grinding
• 36 grit for fast stock removal, weld blending, and surface prep
• 9.125-inch diameter with 0.875-inch arbor hole fits standard large-format angle grinders
• Bulk pack of 25 discs supports production-level usage and reduces downtime

Compatibility

Designed for use with large-format angle grinders and right-angle grinders accepting a 9.125-inch fiber disc with a 0.875-inch arbor hole. Confirm grinder RPM rating meets or exceeds the disc maximum rated speed before mounting.

Installation Notes

Fiber discs of this size should be installed and operated by personnel familiar with angle grinder safety practices. Always inspect the disc for cracks or damage before mounting and never exceed the disc maximum rated RPM. Ensure the grinder guard is in place before operation, and wear appropriate PPE including a face shield, gloves, and hearing protection. Disconnect power to the grinder before changing discs.
