3M 7000119559 Psa Abrasive Disc 400 Grit 6 in 100 Pack

Product Description

The 3M 7000119559 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for fine surface finishing on random orbital sanders. Built on a C-weight paper backing, each disc measures 6 inches in diameter and carries a 400-grit aluminum oxide abrasive rated at super fine grade. The PSA mount allows fast disc changes without hook-and-loop hardware. Aluminum oxide is a durable, self-fracturing abrasive that maintains a consistent cut through the life of the disc. This product ships in packs of 100 discs and is used by finishing carpenters, painters, auto body technicians, and general metalworkers requiring a controlled final-pass scratch pattern before coating or polishing.

These discs are suited for light material removal, surface prep, and between-coat sanding on wood, metal, plastic, and painted surfaces. The flexible paper backing conforms to slightly contoured surfaces, making them practical for finish work on furniture, cabinetry, door panels, and body filler leveling. No vacuum holes are present in this disc, so they are intended for use on non-dust-extraction PSA backing pads. The yellow disc color is consistent with 3M 236U series identification, helping shops quickly sort grit levels at the workstation.

Installation Notes

Ensure the backing pad surface is clean and free of adhesive residue before applying each disc, as contamination will reduce adhesion and cause disc slippage during operation. Press the disc firmly and evenly onto the backing pad before starting the sander. Do not use PSA discs on hook-and-loop backing pads. Discard discs showing loading, glazing, or edge lifting to maintain consistent finish quality.
