3M 7000043524 Psa Abrasive Disc 240 Grit 5 in 175 Pack

Product Description

The 3M 7000043524 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for random orbital sanders used in finishing and surface preparation work. This disc runs a 240-grit aluminum oxide abrasive on an A-weight paper backing, placing it in the very fine grade range — suited for final sanding passes before finishing, light stock removal, and surface blending. The gold disc measures 5 inches in diameter and features 5 vacuum holes for dust extraction compatibility. Sold in a 175-disc pack, it is a standard consumable for cabinet shops, auto body preparation, metal fabrication, and general finishing trades.

This disc is designed for use on wood, painted surfaces, and light metals in residential and commercial finishing applications. The PSA backing allows quick mounting and removal on hook-free backup pads. Random orbital sanders are the primary machine type for this disc. The flexible paper construction conforms to slightly contoured surfaces, reducing the risk of sanding through edges or corners. Tradespeople and finishers working in production environments benefit from the 175-count packaging, which reduces changeover time between jobs.

Key Features

• 240 grit aluminum oxide abrasive for very fine material removal and surface smoothing
• 5-inch diameter with 5 vacuum holes for efficient dust extraction during operation
• A-weight paper backing provides flexibility for slightly contoured surfaces
• Pressure-sensitive adhesive backing for fast disc changes on compatible backup pads
• Gold disc color allows visual wear monitoring during use
• 175 discs per pack supports production-level finishing workflows

Compatibility

Designed for use with random orbital sanders equipped with PSA (smooth) backup pads. The 5-inch diameter and 5-hole vacuum port pattern must match the sander and backup pad configuration in use.

Installation Notes

Remove the release liner and press the PSA disc firmly onto a clean, dry backup pad before operation. Ensure the sander is powered off and disconnected before mounting or removing discs. Align vacuum holes with the backup pad ports to maintain dust extraction performance. Replace discs when abrasive loading or glazing reduces cutting efficiency.
