3M 7000119245 Psa Disc 180 Grit 6 in Silicon Carbide 175pk

Product Description

The 3M 7000119245 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and stock removal on a range of substrates. Built on a lightweight A-weight paper backing, the disc uses silicon carbide abrasive at 180 grit for very fine material removal. The flexible construction conforms to slightly curved or contoured surfaces, making it well suited for finishing passes where consistency matters. At 6 inches in diameter, it mounts directly to PSA-compatible backup pads without fasteners. This disc ships in a pack of 175 units, offering enough quantity for sustained production use in a shop or field environment.

This disc is intended for use with random orbital sanders in both shop and field finishing applications. Silicon carbide at 180 grit is commonly used for final sanding passes on wood, composites, paint, primer, or coated surfaces before finishing or inspection. The gray, flexible disc is part of the 3M 426U series and is well matched to production workflows where consistent scratch patterns and surface prep are required. No vacuum holes are included, so it is appropriate for solid-face backup pads without dust extraction ports.

Key Features

• Silicon carbide abrasive at 180 grit delivers very fine surface finishing performance
• 6-inch diameter fits standard PSA backup pads on random orbital sanders
• A-weight paper backing keeps the disc lightweight and flexible for contour work
• Flexible construction conforms to slightly curved or uneven surfaces
• No vacuum holes — designed for solid-face PSA backup pads
• Pack of 175 discs supports high-volume or production use

Compatibility

Designed for use with random orbital sanders equipped with PSA (pressure-sensitive adhesive) solid-face backup pads. Part of the 3M 426U series.

Installation Notes

Peel the release liner and press the disc firmly onto a clean, dry PSA backup pad before use. Ensure the sander is powered off and disconnected from any power source before changing discs. Inspect the backup pad for damage or contamination that could cause uneven wear or disc failure. Follow applicable shop safety practices for abrasive tool use, including eye and respiratory protection appropriate to the material being worked.
