★How to drill correctly:
1.Firstly, mark the point where you want to drill the hole;
2.Next, fix the drill at the angle of 45°to make a drilling trace at a high rotating speed;and add water during the drilling process;
3.Then drill vertically from the other side of the drilling trace at a slow speed to prevent breakthrough.
1.Please not for use on concrete or for depths beyond about 1/2 ''(12.7mm).
2.please make sure that water must be added during drilling to prevent drill burning.
3.Lower drill speed, its inner pressure and improve the use of water lubrication to protect drill bits considerably.
