3M 7000023949 Nonwoven Abrasive Disc 5 Inch Aluminum Oxide

Product Description

The 3M 7000023949 is a precision-coated nonwoven abrasive disc designed for wet or dry finishing and polishing of contoured surfaces. The disc uses aluminum oxide mineral particles bonded to a flexible nonwoven backing, delivering a uniform, consistent scratch pattern across the work surface. Available in 2.0, 3.0, and 9.0 micron grades, each grade is color-coded for fast selection on the job. The pressure-sensitive adhesive (PSA) backing mounts directly to compatible backup pads without fasteners. Trades and fabricators use this disc to shorten hand sanding cycles and reduce the total number of finishing steps on softer materials.

This disc is suited for finishing and polishing plastics, aluminum, brass, and copper. The flexible nonwoven construction conforms to curved and contoured workpiece geometry, making it effective on formed sheet metal, pipe fittings, machined components, and decorative trim. It is used in fabrication shops, HVAC duct and component work, plumbing fixture polishing, and electrical enclosure finishing where a controlled, repeatable surface finish is required on non-ferrous metals and engineered plastics.

Key Features

• Aluminum oxide mineral on flexible nonwoven backing for consistent, uniform finish
• Use wet or dry — versatile for multiple finishing environments
• PSA backing mounts to standard backup pads without additional fasteners
• Available in 2.0, 3.0, and 9.0 micron grades for progressive finishing sequences
• Color-coded micron grading for quick grade identification
• Reduces finishing steps and shortens hand sanding and buffing time

Compatibility

Designed for use with PSA-compatible backup pads on random orbital and straight-line finishing tools. Suited for finishing softer materials including plastics, aluminum, brass, and copper. PSA-backed discs and sheets are available in 2.0, 3.0, and 9.0 micron grades.

Installation Notes

Mount to a clean, dry PSA backup pad — contaminated or worn pads will reduce adhesion and cause disc slippage. Inspect the disc before use and discard if the nonwoven backing shows tears or separation. When using wet, ensure the tool and operator setup are appropriate for wet grinding environments per applicable shop safety guidelines.
