The Festool HL 850 Planer allows you to create perfectly smooth surfaces as well as distressed or rough-hewn effects with a quick-change cutterhead system that enables you to swap out heads in matter of seconds . Create exotic textures and add character to your work by simply replacing the standard planer head with one of three rustic heads. Produce fine or coarse wavy textures, or a scalloped effect to mimic a hand-hewn appearance. Spiral cutter engages the material with a slicing action, similar to that of a skewed angle hand plane, generating less chatter and a smoother cut. Self-aligning blades for quick and easy blade changes - loosen 3 screws, replace the blade, re-tighten screws and you're done -- Simple as that. Durable, precision ground HSS spiral-cutting blade generates consistent results over a long service life. Precision-balanced machined aluminum head for smooth, vibration-free planing. Includes planer head and blade.
