1. Check the integrity of the TCT hole saw before use.
2. Put the TCT hole saw into the electric drill and then clamp the three planes of the corresponding handle.
3. According to the material you want to drill and adjust the speed of the electric drill to the appropriate range, keep the verticality of the TCT hole saw and the workpiece.
4. Put the TCT hole saw into the material and slowly speed up the speed to ensure the cutting effect and carefully operate to avoid accidents.
5. When drilling, the speed should not be too low, and the collapse caused by cutting blades is stuck.
6. When drilling continuously, use the cutting solution to cool the cutting blade.
7. After the holes are drilled through the workpiece, the workpiece should be exited when the hole drilling is rotated.
8. If the handheld electric drill is used, the use effect will be different due to the difference in power and torque. The thickness of drilling is not more than 3mm.
Please allow 0.5-1 inch difference due to manual measurement.(1 inch=2.54cm)
