Walter Surface Technologies 15Q462 Flap Disc 120 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15Q462 is a Type 27 zirconia alumina flap disc engineered for surface grinding and finishing on an angle grinder. Rated at a maximum of 13,300 RPM, this disc measures 4.5 inches in diameter with a 7/8 inch center arbor hole. The 120-grit, fine-grade abrasive surface is bonded to a plastic backing that supports consistent flap wear and cool cutting action. The trimmable design allows the operator to expose fresh abrasive as the disc wears, extending usable life. Metal fabricators, welders, and maintenance technicians reach for this disc when blending welds or finishing non-ferrous and ferrous surfaces.

This flap disc is suited for use on aluminum, non-ferrous metals, and stainless steel in both light industrial and fabrication shop environments. The Type 27 profile presents a flat grinding face, making it well suited for flat surface work and edge blending. It mounts via an arbor attachment on standard 4.5 inch angle grinders. The fine 120-grit rating positions it as a finishing step following coarser stock removal, producing a smooth surface ready for inspection, coating, or further polishing.

Installation Notes

This disc should be installed and replaced by a qualified operator familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Verify the tool RPM rating meets or falls below the 13,300 RPM maximum before use. Inspect the disc for damage before each use and never operate a cracked or delaminated flap disc.
