Sanding disc pack DeWalt DT3112-QZ 25 pcs — abrasive discs for orbital sanders

DeWalt DT3112-QZ is a pack of 25 sanding discs made for use with compatible orbital and random-orbit sanders. These abrasive discs are intended for surface preparation, smoothing, and removal of paint, varnish or rust on wood, metal and composite materials. The pack supplies multiple consumables to maintain consistent sanding performance during workshop, renovation and professional maintenance tasks.

Advantages

These sanding discs offer uniform abrasive coating and consistent grit profile to provide even material removal and predictable finishing results. The discs are supplied in a quantity suited for repeated jobs, reducing downtime for disc changes. Designed for orbital sanders, they adhere to hook-and-loop backing systems for quick attachment and removal. The abrasive material balances cutting efficiency and surface finish to support stripping, sanding and finishing workflows.

Key specifications

• Pack quantity: 25 discs
• Compatible tool type: orbital and random-orbit sanders

How to use

Select a disc with the appropriate grit for the task and attach it to a compatible orbital sander using the hook-and-loop backing. Begin with coarser grit for paint or heavy material removal, then progressively switch to finer grit discs for smoothing and achieving the desired finish. Use steady, even pressure and keep the sander moving to avoid concentrated wear or gouging. Replace discs when abrasive effectiveness decreases to maintain consistent results.

Usage recommendations

For stripping and heavy removal, start with a coarse grit and complete the process with medium and fine grits for a smooth surface ready for priming or finishing. Wear appropriate personal protective equipment such as eye protection, dust mask and hearing protection, and work in a well-ventilated area or use dust extraction when possible.
