3M 7000118919 Psa Disc 2 in 36 Grit Aluminum Oxide

Product Description

The 3M 7000118919 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Built on an X-weight cloth backing, this disc delivers the rigidity and durability required for high-pressure grinding and shaping applications. The 36-grit aluminum oxide abrasive mineral provides a very coarse cut rate, making it suited for rapid stock removal and surface prep work. The flexible construction allows the disc to conform to slightly contoured surfaces without losing contact. Licensed trades and finishing professionals rely on this disc for bench grinding, disc sanding, and random orbital sanding operations.

This disc is intended for use in light industrial, fabrication, and maintenance-repair-operations (MRO) environments. The PSA backing mounts directly to compatible adhesive-backed platens without clamps or hardware, reducing changeover time during production runs. At 2 inches in diameter, it fits compact tooling used in tight-access grinding and surface conditioning tasks. Machine compatibility includes benchtop motors, disc sanders, and random orbital sanders. The very coarse 36-grit rating makes it most appropriate for initial material removal passes rather than finishing steps.

Key Features

• 36-grit aluminum oxide abrasive for very coarse, high-rate stock removal
• X-weight cloth backing provides strength and flexibility under load
• Pressure-sensitive adhesive mount for fast, tool-free disc changes
• 2-inch diameter fits compact benchtop and handheld sanding tools
• No vacuum holes — solid disc face for full abrasive contact
• Flexible construction allows light contouring without lifting

Compatibility

Compatible with benchtop motors, disc sanders, and random orbital sanders equipped with 2-inch PSA adhesive platens. Part of the 3M 348D series.

Installation Notes

Power down and unplug or lock out the sander before mounting or removing the disc. Align the PSA backing squarely to the platen and press firmly from center outward to eliminate air pockets and ensure full adhesion. Verify the tool spindle speed rating is appropriate for the disc diameter before operation. Worn or glazed discs should be replaced promptly to prevent uneven material removal.
