3M 7000119243 Abrasive Disc Roll 120 Grit 6 Inch

Product Description

The 3M 7000119243 is a coated abrasive disc roll in the 426U series, designed for high-production sanding environments where consistent finish quality is critical. Each roll contains multiple 6-inch diameter discs loaded with silicon carbide abrasive at 120 grit. An anti-load coating combined with open-coat construction resists clogging and maintains cut rate across extended use. The Stikita pressure-sensitive adhesive backing allows fast disc changes and clean removal without adhesive transfer, making multi-step finishing sequences more efficient. This product is used by finishing carpenters, cabinet shops, auto body technicians, and composite fabricators.

The 426U disc roll is suited for white wood sanding, sealer coat sanding, solid surface finishing, and any application where a fine, consistent finish is the target. The A-weight paper backing flexes to follow backup pad contours, which helps maintain even abrasive contact on flat and slightly curved surfaces. Typical applications include production woodworking, fiberglass prep, plastic smoothing, drywall finishing, and clear coat scuffing. The 120-grit rating places this disc in the fine finishing range, appropriate for intermediate to final sanding stages.

Key Features

• Silicon carbide abrasive at 120 grit for fine finish control
• Open-coat construction reduces loading and extends disc life
• Anti-load coating maintains consistent cut and prevents clogging
• A-weight paper backing flexes with the backup pad for uniform contact
• Stikita adhesive backing allows fast attachment and clean, residue-free removal
• Roll packaging supports high-production workflows and organized disc storage

Compatibility

Designed for use with 6-inch Stikita-compatible backup pads on random orbital and disc sanders used in woodworking, auto body, composites, and general surface finishing applications.

Installation Notes

Installation requires a 6-inch Stikita-compatible backup pad mounted to a random orbital or disc sander. Power down the sander before swapping discs. Align the disc centered on the pad and press firmly to seat the adhesive before starting. Inspect the disc for loading or glazing during use and replace when cut rate degrades noticeably.
