Value Collection N03527 Flap Disc 40 Grit Type 27 4.5 in

Product Description

The VALUE COLLECTION N03527 is a Type 27 zirconia alumina flap disc designed for aggressive material removal on metal surfaces. Measuring 4.5 inches in diameter with a 5/8-11 threaded arbor hole, this coated abrasive disc features a coarse 40-grit cut suited for fast stock removal and weld blending. The fiberglass backing provides structural support at operating speeds up to 13,000 RPM. High-density flap construction extends disc life and maintains consistent cut throughout the disc's service life. Licensed tradespeople and fabricators working with angle grinders will find this disc effective for heavy-duty grinding applications.

This flap disc is intended for use on steels and stainless steel in fabrication, welding prep, and surface conditioning applications. The Type 27 flat-profile design keeps the disc flush to the workpiece, making it well suited for flat surface grinding and moderate-angle work. The zirconia alumina abrasive delivers a sharp, self-sharpening cut that holds up under sustained pressure. Sold in a package of five discs, the N03527 suits shop environments where multiple discs are consumed during regular production or maintenance grinding.

Installation Notes

Metal fabricators and welders typically mount this disc on a standard angle grinder equipped with a matching 5/8-11 arbor nut. Confirm the grinder's rated RPM meets or exceeds 13,000 RPM before mounting. Inspect the disc for damage before each use and never operate a cracked or delaminated disc. Always wear appropriate PPE including face shield, gloves, and hearing protection when grinding.
