Dynabrade 78130 Coarse NWN Dynabrite Locking-Type Disc 4" 102 mm DIA

The Dynabrade 78130 Coarse NWN Dynabrite Locking-Type Disc 4" 102 mm DIA conditions and cleans surfaces using a non-woven abrasive structure that contacts the working parts as the disc rotates. Its open-web construction allows debris to pass through the substance, reducing buildup while maintaining continuous abrasive contact during operation. This disc attaches to compatible backing pads through its locking-type mounting system and is positioned on rotary power tools designed for surface-finishing applications. The coarse grade is effective for removing oxidation, cleaning metal surfaces blemishing imperfections, and preparing components for subsequent coating, finishing, or assembly processes.
