TIPS
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.
Keep a light touch, letting the speed of the tool do the work. This helps your accessories last longer.
