Heat Fused Drilling Processing
1. Mark the hole in the lid of the cooler.
2. Bake in a gas flame while turning the pipe.(about 30 seconds)
3. Put the burnt pipe vertically and lightly press it into the seal position of the lid.
(Note: If the pipe is sideways, the hole is larger and may cause water leakage.)
4. Drill the burrs around the hole (top and bottom, inside and out) with a knife, etc., to complete the drilling process.
