Value Collection N03528 Flap Disc 60 Grit Type 27 4.5 in

Product Description

The VALUE COLLECTION N03528 is a Type 27 coated flap disc designed for aggressive material removal and surface blending on metal workpieces. Built with zirconia alumina abrasive at 60 grit, it delivers medium-grade cutting action suitable for weld blending, deburring, and surface preparation. The disc measures 4.5 inches in diameter and mounts via a 5/8-11 threaded arbor hole for secure attachment to standard angle grinders. A fiberglass backing plate provides rigidity and stability under load. The high-density flap construction extends disc life and maintains consistent stock removal throughout the disc's usable life. Rated to 13,000 RPM, it meets the demands of continuous-duty shop and field use.

This flap disc is suited for fabrication shops, metal service centers, and field welding operations where consistent surface finishing on steels and stainless steel is required. It is appropriate for use in both light industrial and heavy fabrication environments. Typical applications include weld seam blending, scale removal, and surface conditioning on carbon steel and stainless steel workpieces. Sold in a package of 5 discs per unit, making it practical for stocking at the job site or shop bench.

Installation Notes

Installation and use should be performed by operators familiar with angle grinder safety practices and applicable ANSI B7.1 standards for abrasive wheel use. Always verify the grinder's no-load RPM does not exceed the 13,000 RPM disc rating before mounting. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for cracks or damage before each use and do not use damaged discs.
