Description
A hole saw you use with your screwdriver to drill holes in the lid of your container.
A spring pushes out the piece you removed.
Available in three sizes. One for our 32 mm baskets (33 mm drill) and one for our 50 mm baskets (44 mm drill) and one for our 80 mm baskets (78 mm drill). Fits all screwdrivers, the attachment is 10 mm.
Drill at a very low speed otherwise the plastic will melt and leave a smaller and uneven hole.
Sometimes you have to clean the hole with a file or knife.
The hole should be slightly smaller than the basket so it is held securely and does not tip over as the plant grows larger.
