The newbie could be holding out to see if we give same information he found somewhere else. He may want an unbiased opinion.
If the insert and alloy are unknown:
Steel 400 SFM and .005 per rev
Nickel Alloys 200 SFM and .005 per rev
AL alloys no limit on speed, feed .005 per rev
These are safe starting points given the information you have offered. You would see much higher starting points in most Mfg's catalogs. You will most likely need to adjust these parameters to acheive desired finish, chip formation and production rates.
