Ok, maybe more @switchpod bait here.
I am looking at drilling through some stainless steel with different drills (can you smell a new 80% build going on?).
I have been using the calculator at https://littlemachineshop.com/reference/cuttingspeeds.php#Drilling to put in my drill bit size (there are a few different sizes needed for this build). And just need a second set of eyes on the math.
For instance, I will be using a #9 drill bit. On the calculator, I used 50 FPM and a size of .196 inches (Grabbed from here https://littlemachineshop.com/reference/numberdrillsize.php) That gave me an RPM of 974.
Is that correct? I would have thought it to be a little faster than that.
