We're running a job that requires drilling a #30 (.1285) hole thru 1" of 303/304 stainless mill bar. This material is known to have hard spots that really affects the drill life. We're currently drilling this hole with a RedLine® RDH series coated carbide drill.
This job is being run on a Hurco VMX24 without thru spindle coolant.
We've been thinking about buying a thru spindle coolant adapter but I have never used one before.
Could someone give me the low down of these? Do we need a higher output coolant pump? Can this tool still be used with the tool changer? And of course what would the cost be to set this up in our machine?
