1. Twist drill is a cutting tool, mainly used for metal drilling, so the control of speed is critical.
2. When using manual drilling, pay attention to adjust the speed. The drill bit may be damaged if the speed is too fast.
3. The larger the diameter, the slower the speed requirement.
4. This product is not percussive in use, the work must be fixed, work swing during operation will break the bit.
5. Drill the metal with high hardness and impurity, rotate speed is slower than normal drilling, and the cooling effect is better.
6. For products with large thickness, if abnormal cutting occurs, please remove the debris in time.
