Two cutters included.Features For wood, fiberglass, plastic and soft materials Not for use with hardened materials For detail engraving, carving and routing Use higher speeds for hard woods, slower speeds for metals 1/8 In. shank 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. Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics (to avoid melting at the point of contact). If chattering occurs, increase speed. Use the sides of the cutter (rather than the tip) for effective cutting. The tip cuts poorly and can break under pressure. Secure objects to a stable surface while working.
