I made a 2-way drill press machine.
This drill press is an improved version of the drill guide released in January 2019. https://youtu.be/rqn46zl_OkA
The base of the drill press machine is removable.
By removing the base, you can also make holes in large boards or on walls, etc.
The base has a T-slot, and you can attach a clamp etc. to work.
