So im currently drilling alot of deep holes in our mould. Ive pre-drilled all the holes 3" deep with a shorter drill before going in with a longer drill to reach the required depth. My question is, is there a way to get it to start 2.9" down inside the holes, but come back up past the top of the piece for chip clearance. Right now we have it cutting 3" of air before it even starts to cut material. And add on top of that if the drill dulls having to sharpen it and start that hole all over again.
Thanks.
Thanks.
