A versatile, high-quality cutter made of high-grade steel for use on wood, plastic and soft metals.Use Tips For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collet or chuck to hold onto the bit. If chattering occurs, increase speed. Secure objects to a stable surface while working. Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics (to avoid melting at the point of contact). Use the sides of the cutter (rather than the tip) for effective cutting. The tip cuts poorly and can break under pressure.
