High-Performance Flap Discs for Heavy-Duty Sanding & Grinding

When working with metal, wood, or plastic, having the right abrasive tool makes all the difference. The Flap Discs 4-1/2″ x 7/8″ (40 Grit, 10 Pack) are designed to deliver fast material removal, smooth blending, and durable performance for professionals and DIY enthusiasts alike. These discs provide aggressive grinding capabilities while maintaining a long lifespan, making them a cost-effective and reliable choice for any workshop.

Premium Quality for Maximum Efficiency

Crafted with industrial-grade zirconia alumina, these flap discs outperform traditional sanding discs by lasting longer and grinding more efficiently. Zirconia alumina is self-sharpening, meaning it continually exposes fresh abrasive particles as you work, reducing downtime and maintaining cutting power over extended use.

Key Features & Benefits:

High-Quality Zirconia Alumina: Long-lasting and self-sharpening for increased durability.
40 Grit Coarseness: Ideal for heavy material removal, deburring, and weld grinding.
Universal 4-1/2″ x 7/8″ Size: Fits most angle grinders, providing versatility.
T-29 Angled Design: Enhances grinding efficiency on both flat and contoured surfaces.
Resin Fiber Backing: Reduces vibrations and improves stability.
Multipurpose Use: Effective on metals, wood, plastics, and composites.
10-Pack Value Bundle: Provides multiple discs for extended use.

T-29 Angled Design for Superior Performance

The T-29 (conical) shape offers better surface contact, making it easier to grind curved and flat surfaces with precision. This shape allows for a higher cutting efficiency, reducing the amount of pressure needed while working. Whether you’re smoothing out weld seams or grinding down rough edges, the T-29 design ensures a consistent, smooth finish.

Ideal Applications

These 40-grit sanding discs are perfect for a variety of applications, including:

🔹 Metal Fabrication – Smooth out welds, remove rust, and shape metal parts.
🔹 Woodworking – Strip paint, shape wooden surfaces, and remove rough edges.
🔹 Automotive Work – Prep surfaces for painting and remove coatings.
🔹 DIY & Home Improvement – Use for general sanding and restoration projects.

Compatibility & Easy Installation
