3M 7000148148 Psa Disc 5 in 100 Grit Aluminum Oxide

Product Description

The 3M 7000148148 is a pressure-sensitive adhesive (PSA) abrasive disc designed for material removal and surface finishing in trade and industrial applications. Measuring 5 inches in diameter, this disc features 100-grit aluminum oxide abrasive in a fine grade, bonded to an X-weight cloth backing for durability under moderate to heavy grinding loads. The flexible construction allows the disc to conform to slightly contoured surfaces, making it suitable for both flat stock and mild profile work. Licensed tradespeople and shop operators use this disc for consistent, repeatable results on metal and similar substrates.

This PSA disc is suited for bench-top motor grinders and random orbital sanders in professional fabrication, maintenance, and repair environments. The pressure-sensitive adhesive backing allows for straightforward mounting to compatible backup pads without mechanical fasteners. No vacuum holes are included, so this disc is intended for use on solid backup pads without dust-extraction ports. The maroon-colored disc belongs to the 3M 348D series and is sold individually, with a minimum order quantity of 50 units per order.

Key Features

• 100-grit aluminum oxide abrasive for fine-grade material removal and surface prep
• 5-inch diameter fits standard PSA backup pads for bench-top motors and random orbital sanders
• X-weight cloth backing provides strength and flexibility for conformable grinding
• Pressure-sensitive adhesive mount — no mechanical fasteners required
• Flexible disc construction allows use on mildly contoured work surfaces
• No vacuum holes — designed for solid (non-perforated) backup pads

Compatibility

Compatible with bench-top motor grinders and random orbital sanders equipped with 5-inch PSA (pressure-sensitive adhesive) solid backup pads. No vacuum hole configuration means this disc is not suitable for dust-extraction pad systems.

Installation Notes

Installation is performed by a qualified shop technician or trades professional. Power down and disconnect the sander or bench grinder from its power source before changing discs. Peel the liner from the adhesive backing and press the disc firmly and evenly onto a clean, dry backup pad to ensure full adhesive contact. Inspect the disc for tears or delamination before each use and replace immediately if damage is found.
