Do not use these bits for drilling into very hard materials, such as glass or ceramics. 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. Insert an 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. Keep a light touch, letting the speed of the tool do the work. This helps your accessories last longer.   Specifications:  COLOR CODE: DimGray * DESCRIPTION: Drill Bit Set * MODEL NUMBER:628-01
