What grade of stainless are you trying to process?

Since it's clearly not a free machining grade and is probably an martensitic type, some care has to be taken when working with it. You need to understand the metallurgy behind the part before you start.

Non-free machining Stainless, with its high carbon and alloy content, does two things while cutting: Work harden, and heat treat itself. This makes it difficult to grind more than just a surface finish off of. (Also, grinding a lot of stainless releases hexavalent chromium, which is a very big OSHA no no without ppe and dust management!)

You have to hog big, deep passes at a relatively low SFM to avoid work hardening at the surface you are trying to cut. Never cut shallow unless it is THE last pass, and never allow it to dwell for even a whole revolution- power feed all the way. You need coated carbide. aggressive tip relief and lead angles. It also must be worked with heavy flood coolant, as ANY heat buildup at the surface (eg from a grinding wheel or an even slightly dull cutter) will simply harden the surface right into the Rockwell C range and you'll have a bad time. You could put the point ok using a lathe like this.

You could part off the stock in a lathe fine, a typical bandsaw blade probably isn't hard enough. Ideal would be a cold cut saw probably, but if you don't have one handy that's $$.

However, what this all leads back to is the design requirements: is a hard stainless really needed? Do they need something so tough, or are they mostly for corrosion resistance? You could switch to a free machining Stainless with similar corrosion/heat resistance and eliminate a lot of these special problems.

Our last metal order was 304 stainless, if that makes a difference.

Purpose is to make electrodes for use in scientific imaging. They are pounded into the ground with a 2lb sledge, and wired up to a scientific apparatus. Electricity is injected using the electrodes and then we measure where the current flows in the subsurface to make a map of the electrical conductivity/resistivity of the subsurface materials. We then remove the electrodes and reinstall them at a new location. They take a beating.

It's stainless due to being in a corrosive environment, often wet, sometimes salty. We also have to be a little careful with the metal choices so that there is not a strong galvanic self-potential created. 304 stainless (or similar) seems to strike a nice balance between corrosion resistance, reusability (standing up to being pounded into most materials), and lack of strong galvanic response.
