Festool Saphir Abrasives are for the 6" Rotex RO 150 E dual-mode sander and ETS 150/3 EQ and ETS 150/5 EQ random orbital sanders. These 6" Saphir abrasive discs are designed for heavy-duty use and feature the next generation Multi-Jetstream design that incorporates a modified 17-hole pattern to increase airflow, and results in even better dust extraction efficiency. These new pads also incorporate an enhanced, heat-resistant StickFix design, extending both pad and abrasive life considerably. The new Multi-Jetstream design is 100% compatible with the previous pad design, and vice-versa. Available in either 5 sheets/pack or 25 sheets/pack.
