Hello,
I am hoping someone can give me a good procedure to drill 11/16th hole in 3/16th box tube. I have a drill press (rigid 5/8 shank), 11/16th split tip drill.
I am not sure if I should drill series of pilot holes (smaller to larger never had much luck there) or merely center punch and use the 11/16 drill bit. I need the hole on both sides of the tube and am leaning towards going slow with cutting oil.
Any advice would be appreciated, thanks
