Guidelines for the Use of Drilling Tail Screws:
1. Check the speed of electric drill to ensure that the power of electric drill is 600W and the speed is 2000-2500 RPM.
2. Apply a hand force of about 14 KG to the electric drill to ensure that the force is on the same vertical line as the center point.
3. When the electric drill is in operation, it can't stop halfway. When the screw is in place, the signal speed stops drilling.
