Product Feature
High-Strength 0.8mm Steel Paper Backing
A robust 0.8mm thick steel paper backing provides exceptional durability and consistent flatness, making these 4-inch fiber discs ideal for precision surface grinding on metal and wood.
Uniform High-Performance Alumina Abrasive Grain
Premium aluminum oxide grains are evenly distributed across the disc surface, delivering a consistent cut, extended disc life, and a smoother finish on a variety of materials.
Durable Resin Bond System
These fiber discs feature a strong resin bond that securely anchors the abrasive, offering enhanced heat resistance, greater wear performance, and reliable performance under high-speed grinding conditions.
Optimized Dust Extraction Design
The anti-clogging surface and open structure allow for efficient dust removal, reducing heat buildup and improving both visibility and grinding efficiency during operation.
Easy Installation for Angle Grinders
Designed for quick mounting on standard 4-inch angle grinders, these discs work with a backing pad and nut for secure attachment and easy changes-minimizing downtime.
