1. How to use the multifunctional punching drill
The impact drill is a tool that relies on impact force to drill holes. It is often used to drill holes in bricks, blocks and lightweight walls. The use of the impact drill is as follows:
1. Before drilling, mark the position of the hole on the wall with a pencil or chalk, and hit the center of the hole with a center punch.
2. Select a straight, sharp, non-destructive impact drill with the same hole diameter, open the chuck of the impact drill, insert the drill to the end, and use the chuck key to tighten the chuck.
3. Select the appropriate drilling speed (low speed when the hole diameter is large, and high speed when the hole diameter is small). When drilling hard walls and stones, connect the impact attachment of the impact drill.
4. Hold the impact drill tightly with both hands, place the drill tip in the pit impacted by the center punch, make the drill bit form a 90° angle with the wall, start the impact drill, and use it evenly in the direction of the drilling.
force and keep the drill bit perpendicular to the wall.
5. During the drilling process, remove the drill bit from time to time to remove drill cuttings until the drilling operation is completed.
