Built with aluminum oxide abrasive on a flexible cloth backing, this disc delivers consistent stock removal at 40 grit, a coarse grade suited for grinding welds, shaping edges, and removing surface coatings. The PSA mount allows fast disc swaps on compatible 3-inch backup pads without the need for additional fasteners. Metalworkers, fabricators, and finish carpenters reach for this disc when initial material removal is the priority.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for use on angle grinders, random orbital sanders, and drill-mounted backup pads that accept 3-inch PSA discs. The 40-grit coarse grade makes it a first-stage disc in multi-step finishing workflows, particularly for weld grinding, rust removal, and surface preparation ahead of finer grits. The flexible cloth backing conforms slightly to curved or irregular workpiece profiles, making it practical for contoured stock. No vacuum holes are present, so this disc is intended for open-face sanding without dust-collection port alignment requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch diameter PSA disc for quick, adhesive-backed mounting on compatible backup pads\u003c\/li\u003e\n  \u003cli\u003e40-grit aluminum oxide abrasive for aggressive coarse-grade stock removal\u003c\/li\u003e\n  \u003cli\u003eFlexible cloth backing conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — designed for standard open-face grinding and sanding applications\u003c\/li\u003e\n  \u003cli\u003eBlack disc color for easy grit identification on the shop floor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement for 3-inch PSA abrasive discs used on angle grinders, drill pads, and orbital sanding tools that accept pressure-sensitive adhesive backed discs with no vacuum holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by trades workers and fabricators requiring no special licensing. Ensure the backup pad surface is clean and free of adhesive residue before mounting to achieve full PSA contact. Power down and disconnect the tool from its power source before swapping discs.
