I do loads of SS too and I find too much pressure is as bad as too little. I let it bite and keep it at a steady firm feed.loads of pressure

I go through loads of it.don't forget cutting compound

makes a big difference .not cutting oil but compound and I've cut and drilled a lot .there's less friction and easier cutting as well as your drills and saw blades lasting a lot longerI am not talking hanging off the handle on small drills but shoving a 25mm drill needs a fair bit of pressure.
Likewise with the sharpening, only a light touch usually required. Most of my work is stainless whether that be turning, milling or welding. When a drill starts clicking in stainless it is time to give it a light touch on the grinder.
Let stainless rub and as you say it work hardens and then it needs carbide. I often get people bringing stainless in that they have tried to drill themselves and hardened it and they blame the drills they have been using, they ask where they can buy the drills that are meant for stainless. I sometimes give them one of mine and they come back and say it was rubbish and don't believe that I gave them a proper drill. I sharpen it and show them that it is fine.
As said I very rarely use cutting oil on the drill, used to use it all the time in my early days but found it makes little difference in most cases.
Saws, Mills and Lathes usually have flood coolant although sometimes it is actually worse milling stainless with flood, depends on coating etc, but hey every one to there own. I am self taught and often do things unconventionally but have learned by doing this for a living for more years than I care to mention.makes a big difference .not cutting oil but compound and I've cut and drilled a lot .there's less friction and easier cutting as well as your drills and saw blades lasting a lot longer
Yeah it's all I use on my saw is the water oil mix.Saws, Mills and Lathes usually have flood coolant
Cutting oil is great for pilots as it's no where to go but do it's job. After that not so useful dripping all over the floor as it runs through the hole. Compound is awsome
It doesn't just keep bits going it aids to cut better too.
I have to really.That is something else I very rarely do, I may use a NC or Centre drill but very rarely pilot anything.
I find Rocol RTD does the job for me.
