Advice needed: drilling .030 and .050 holes in 304 stainless
Hello all,
Ive decided I despise 304. Im slightly spoiled and run mostly 303 so im on a bit of a learning curve and figure the wise ones on this board might be able to save me some broken drills and frustration.
Here what's up. Both jobs described below are in 304 stainless steel.
I need to drill a .052 hole .300 deep. I was thinking 6k rpm, .010 peck and .0004 or 5 feed. Hows that sound? I only need to make 150 pieces for that job.
The one im really dreading is a 500 piece job with a .036 hole .430 deep. Hows 7k or 8k rpm, .007"? peck at .0003 ipr?
How many tools should I order for this one? Also do you think its worth buying expensive 12xD or 15xD carbide drills? or just a crap load of HSS?
I havent made holes this small for a while and wasnt programming when I ran jobs like this.
Any help or general 304 advice is appreciated. In general what do you guys use for turning SFM, feeds, and how much corner rad on your turn tool?
Thanks!
