Is a cobalt drill bit the best when drilling through steel?
I have tried using a titanium drill bit and all I made managed to make is a dimple in the metal.
High speed steel bits are fine for drilling through most mild steels. You need to use a set punch to put a start dimple on the steel. You need to use the proper amount of solid downward pressure and oil to cool your drill bit.
Do not use excessive speed or no lubrication. You’ll dull or break a new bit.
A drill press is a good way to have the constant speed and pressure to drill though steel.
