Common Sizes

Diameter: 4 inches (100mm), 5 inches (125mm), 6 inches (150mm), etc., suitable for different power Angle grinder or sander.

Aperture: The center hole is usually 5/8 inch (about 16mm), compatible with most sander spindles.

Thickness: The thickness of the abrasive layer is generally 0.5-1.2mm, and the back pile layer is about 0.8-1.5mm, which balances durability and flexibility

1. Abrasive material: Alumina (Al₂O₃)

High hardness: the Rockwell hardness of alumina is second only to diamond, and the wear resistance is dozens of times that of high chromium cast iron, which can significantly improve the durability of the sanding sheet.
High temperature resistance: alumina melting point up to 2072°C, suitable for high temperature environment during high-speed grinding, reducing deformation or failure caused by overheating 12.

2.Backing material: back velvet (Hook & Loop, Velcro)

Strong adhesion: The back velvet design provides uniform adhesion, ensuring that the sander is tightly fitted to the sander, reducing the risk of falling off.
Damping effect: The suede material can cushion the vibration during grinding, improve the handling comfort, and reduce the risk of scratches on the material surface
