We have some prototypes coming up. This will possibly (make that very likely) turn into a regular job where we'll make thousands and tens of thousands of parts.
The previous version was non-stainless steel. We went from running with coolant drilling those, to air cooling at the request of the customer.
This is stainless. Recycled stainless, as cheap as you can get it. I'm assuming around 304 quality but I'm also assuming quality could vary wildly.
The customer would prefer if we could machine the parts dry for some reasons unimportant to the question. If not, oh well.
We are talking 4.6, 5.0, 5.2, 6.2, 10.2-millimeter holes through 8 millimeters stock. So, it really isn't deep drilling.
For cheap non-stainless steel we've used Kennametal solid drills, they worked like a dream.
Is dry drilling stainless with through-spindle air cooling feasible in this setting, and if so what are your tips?
