Keep your routing work razor-sharp and precise with the Festool hm-wp 50X5,5X1,1 replacement blades. These carbide reversible blades feature two cutting edges, allowing you to simply flip the insert to continue routing with a fresh, sharp edge. By changing the blade instead of resharpening, your cutter tool such as model 491110 retains its exact cutting diameter for consistent accuracy. This set contains 4 replacement blades of 50 mm in length, complete with 3 countersunk screws and a T8 tx key for quick, hassle-free installation on the job.
