Need suggestions for drilling .81 deep .037 dia. in X15t.n which is similar to 420 SS.
Running Citizen C16. Using Atom ADLL series carbide Drill.
Ran this part in 440C for over a year with no problem part was changed to X15t.n now it is wreaking havoc on my drills.
Any suggestions for feeds, speeds and or peck cycle data would be appreciated!
