Drilling hole of 0.0310" with deepth 0.91" of AISI 304L
Drilling hole of 0.0310" with deepth 0.91" of AISI 304L
(OP)
Hello,
I need your help for drilling AISI 304L.
The holes diameter is 0.0310" ± 0.0030" and the holes depth is about 0.9100".
I found a tool of Walter which has a spiral length of 0.98" and total length of 1.81".
Walter catalog number is A1511-0.8
The questions are:
1. Is it possible to make this hole using Walter tool?
2. What is the cutting data I should use?
3. What is the machining strategy?
4. Should I use more tools with different diameters in order to get this hole?
Thanks

If you only need 1 and can afford to scrap 9 then maybe you could get lucky and drill it.

Holding +/- 0.003 might be a different story, but with a good drill, it is possible.
I'd try it before giving someone a firm quote or cementing the design.
Just my 2 cents.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

so deep. What is the .031 hole used for? Can it be counterbored
part way and then drilled thru.

your best bet of trying to drill it and avoid having 10 scrap parts is to buy 10 scrap drills and use high speed, low-low-low feed.
