Bamboo is a perforated tenon. If it is opened, what tools can be used to save effort?

Find a thicker steel bar and burn it red on the stove, so that you can burn a hole in the required position on the column.

Other opening methods:

1. Put the bamboo on the ground first, and then connect the electric drill to the power supply.

2. Then put the electric drill on the bamboo, drill a small hole in the hole, and use the electric drill on it, preferably with a thinner needle.

Step on the bamboo with your feet, keep still and drill holes along the rope.

4. Then make a round hole around it.

5. When using the electric drill, turn off the switch and cut off the power supply.
