As I am setting up garden edge boards from 200x50 treated pine.
I am using galvanised pickets that I have cut into short sections to hammer them into the ground and screw the edge boards to them.
The lower sections of the cut star pickets have no holes for my gal coach screws. I am drilling holes in them or rather trying to.
The metal is very tough and it takes a lot of effort even with cobalt twist drill bits and use of lubricant. What are these bloody pickets made from? This steel is very tough. Rpms are suitable for the drill diameter and copius lube is used.
The holes drill like they are work hardening. Are there any farmers around who have had to drill holes in star pickets and can pass on some suggestions?
I wonder is there anything that I have not considered and should be aware of ?
