4" Silicon Carbide Hook C Loop Sandpaper with Knock Out Center

Upgrade your sanding performance with our premium 4" Silicon Carbide Hook & Loop Sandpaper Discs featuring a smart knock-out center design. Whether you're smoothing out rough surfaces or refining the final polish, these discs deliver consistent results across a wide range of grits—from coarse 60 to ultra-fine 600. Constructed with pure-grade silicon carbide on heavy-weight backing paper, they ensure superior durability and fast cutting action. These discs are compatible with most hook & loop sanding systems and are perfect for both industrial and home use.

Each box contains 50 discs and is optimized for wet or dry applications, giving you full control over your sanding method. The removable knock-out center offers dual functionality—keep it intact for dry sanding or remove it for center-feed water sanding, ideal for stone or glass polishing. Designed to match or exceed leading brands, these sanding discs guarantee professional-grade results without the premium price tag. Achieve smooth, even finishes with fewer disc changes, and take on any surface with confidence.
