3M 7000043523 Psa Abrasive Disc 150 Grit 5 in 175 Pack

Product Description

The 3M 7000043523 is a pressure-sensitive adhesive (PSA) abrasive disc designed for use with random orbital sanders in surface preparation and finishing applications. Each disc measures 5 inches in diameter and carries a 150-grit aluminum oxide abrasive, placing it in the very fine grade range. The paper backing is A-weight, providing a flexible, conformable cut that tracks well on contoured and flat work surfaces. Five vacuum holes are integrated into each disc for effective dust extraction during operation. This disc is sold in a pack of 175 and is suited for installation and maintenance professionals who require consistent, controlled material removal and finish quality.

These PSA discs are appropriate for residential and light commercial surface prep work including wood finishing, paint scuffing, and substrate smoothing prior to coating or bonding. The 150-grit very fine rating makes them most effective in intermediate to final-pass sanding stages rather than aggressive stock removal. The gold-colored paper backing and aluminum oxide abrasive combination are well-suited for dry sanding operations on wood, painted surfaces, and similar materials. Random orbital sander compatibility ensures reduced swirl marks and a uniform finish across the work surface.

Key Features

• 150-grit aluminum oxide abrasive for very fine material removal and finish control
• 5-inch diameter PSA backing attaches directly to hook-free sander pads
• A-weight paper backing provides flexibility for both flat and contoured surfaces
• Five integrated vacuum holes support dust extraction and extend disc life
• Compatible with standard random orbital sanders
• Pack of 175 discs reduces restocking frequency in high-volume applications

Compatibility

Designed for use with random orbital sanders equipped with 5-inch PSA backing pads. Vacuum hole pattern supports dust collection systems integrated into compatible sanders.

Installation Notes

Ensure the sander backing pad is clean and free of debris before applying each disc to maintain full PSA adhesion. Align vacuum holes with the sander pad ports before pressing the disc firmly into place. Discs are intended for dry sanding use and should not be used with water or liquid lubricants unless the sander and application specifically support wet use. Follow tool manufacturer guidelines and applicable safety standards when operating orbital sanders in occupied or enclosed work areas.
