Festool 499093 Rubin 2 125mm P40 Disc Abrasives, 50-Pack builds on the industry-leading performance of the Rubin abrasive to set a new standard for efficiency, making it for all wood-finishing applications. This all-new Rubin 2 is designed to minimize the time spent on each sanding level with a 30% faster removal rate and a 30% longer sheet life. You can finish faster because Rubin 2 quickly sheds wood fibers, preventing clogging and keeping the abrasive sharp. This leads to a significant increase in removal speed. Additionally, it helps you by lasting up to 30% longer due to its resistance to clogging from pitch and wood fibers. Rubin 2 is also engineered for rapid grit progression, allowing you to move swiftly from 80 to 220 grit and achieve possible finish surface in less time. Model Number: 499093
