I am trying to drill hole out from 0.310 to 0.3125. I drilled about 6 holes like that , and the drill bit is brunt. Now, as soon as I start drilling, the drill bit starts smoking. What speed and feed should I be drilling at. I am not sure what steel I am trying to drill, it may be spring steel, it does not rust though. I know I am probally trying to feed it too fast .
Also, I don't have my coolant working right now. I put a little bit of coolant on now by hand, but it is probally more of a lubicant right now them a coolant. So that I is probally also some of my problem.
Thanks
