The Dust Extracting Nozzle is designed for use with the Makita compact routers when using the fixed trimmer base (compact routers include the 1-1/4 HP Compact Router model RT0701C, and 18V LXT Brushless Compact Router model XTR01, sold separately). When used in conjunction with a Makita Vacuum or other vacuum system, it limits the amount of sawdust expelled into the air by the router. The Nozzle is constructed with high-quality plastic for durability and long life.
