Hi,
I am looking for the most efficient way to drill approx 65 - 7/8" dia holes in flat, 1 1/2" thk carbon steel plate on a CNC mill. We currently use a high speed drill for this operation which seems time consuming with the pilot holes, pecking, and slow feed drill rate.
We have heard the Sumitomo 3xd replaceable thru coolant w/ 7/8" dia drill tip inserts would work best for this operation.
Is this the way to go? Other suggestions?
Thanks,
