So the job hit again. I talked to the PM community b4. The job is drilling 1045 round 1 1/4 dia
7 holes 1/4 dia. We were using 1/4 cobalt screw machine length drill running it at 1300 rpm with a 12 IPM. I called a supplier he suggested a WIDIA solid carbide drill. He told me to run it at 4620 rpm with a 41 IPM feed with a .250 peck. The Hass mill has no coolant through.Set it up never ran solid carbide b4 does this sound right?
