3M 7100026615 Abrasive Disc Roll 180 Grit 5 Inch 426U

Product Description

The 3M 7100026615 is a Stikita 426U coated abrasive disc roll designed for high-production sanding environments where consistent finish quality is critical. Each roll contains multiple 5-inch diameter discs with 180-grit silicon carbide abrasive bonded to a lightweight A-weight paper backing. The open coat construction and anti-load coating work together to resist clogging and deliver a uniform cut across successive passes. Licensed HVAC techs and finishing professionals in woodworking, auto body, and construction trades reach for this roll when throughput and finish consistency both matter.

This disc roll is suited for white wood sanding, sealer coats, solid surface finishing, and any application where a fine finish is the priority. It also performs reliably on metal, plastic, drywall, fiberglass, glass, clear coat, and ceramic substrates. The Stikita pressure-sensitive adhesive backing attaches quickly to compatible hook-and-loop or PSA backup pads and releases cleanly, making it practical for multi-step finishing sequences without leaving residue or slowing changeovers.

Key Features

• 180-grit silicon carbide abrasive for fine, consistent material removal
• Open coat construction reduces loading and maintains aggressive cut throughout disc life
• Anti-load coating minimizes clogging on resins, sealers, and soft substrates
• Lightweight A-weight paper backing flexes to conform to backup pad contour
• Stikita PSA adhesive allows fast attachment and clean removal during multi-step processes
• Roll packaging supports high-production workflows with quick disc access

Compatibility

Designed for use with 5-inch PSA backup pads on random orbital and straight-line sanders configured for vacuum or standard disc use.

Installation Notes

Disc replacement should be performed with the sander powered off and unplugged. Align the disc squarely over the backup pad before pressing to seat the adhesive evenly and avoid edge lift. Inspect the backup pad surface for debris or dried adhesive residue before attaching a fresh disc, as contamination reduces bond strength and can cause disc slippage during operation.
