Drilling and tapping 304L plate.
(OP)
I need to drill and tap approximately 30 holes in a two inch thick baseplate made of 304L stainless. Is there a need for special drills and taps?

RE: Drilling and tapping 304L plate.
drills 118 deg point angle, 10-12 deg lip relief, 120-130 deg chisel angle, 24-32 deg helix
Extensive data can be found in The machinist Handbook as to recommendations. Sorry I don't have on on my desk right now, someone walk off with my copy :( .

Tapping speed should be around 5.5 m/min (18 sfm). Tap should be a typical tool steel like M1, M7, or M10.
As Rich2001 mentioned, use a lot of lubricant during drilling and tapping.
