3M 7010300624 Stikita Sanding Disc 6 Inch 320 Grit

Product Description

The 3M 7010300624 is a 6-inch pressure-sensitive adhesive sanding disc using aluminum oxide abrasive at 320 grit. The Stikita attachment system allows the disc to press directly onto a compatible vinyl backup pad without hardware or fasteners. Aluminum oxide is a self-fracturing mineral, meaning it continuously exposes fresh cutting edges during use, sustaining cut rate and resisting loading across the disc life. These discs are suited for finish sanding and surface prep work in automotive refinishing, bodywork, and light fabrication environments where a consistent scratch pattern and easy disc changes are priorities.

These discs are designed for use with dual-action orbital sanders paired with vinyl backup pads. At 320 grit, they are appropriate for scuff sanding between coats, paint prep, primer leveling, and light surface finishing on materials including paint, primer, fiberglass, metal, and sheet molding compound (SMC). The peel-and-place design reduces downtime during disc changes, which is a practical advantage in production bodywork and refinishing shops. Discs are sold in packs with a minimum order quantity of 10.

Key Features

• Self-fracturing aluminum oxide abrasive sustains cut rate and resists loading for extended disc life
• Stikita pressure-sensitive adhesive backing presses onto vinyl backup pads without clips or hooks
• 6-inch diameter fits standard dual-action orbital sanders with compatible vinyl pads
• 320 grit finish suitable for between-coat scuffing, primer leveling, and surface prep
• Compatible with paint, primer, fiberglass, metal, and SMC substrates

Compatibility

Designed for use with vinyl backup pads and dual-action orbital sanders accepting 6-inch pressure-sensitive adhesive discs. Suitable for automotive refinishing applications involving paint, primer, fiberglass, metal, and SMC surfaces.

Installation Notes

Ensure the backup pad surface is clean and free of debris before pressing the disc into place to achieve full adhesive contact. Power down the sander before attaching or removing discs. Peel the disc away from the backup pad after use by pulling at a low angle to preserve pad condition. Inspect the backup pad regularly for wear, as a damaged pad surface can affect disc adhesion and scratch pattern consistency.
