Any engineers in the house(stainless steel turning question)
303 is probably the easiest to machine. Not the most corrosion resistant but fine for most things. You wouldn’t need any special tooling for it. Plenty of cooling fluid though if you’re taking big cuts.
If you’ve just got some unknown bit of stainless bar, then your guess is a good as mine 🙂Posted 4 years agostevewhyteMember
As been said, your not talking about bushes, if you are you want something softer than the shaft.
I would us a tungsten carbide tip for any stainless, even just drilling through relatively thin ss. You can chew through hardend steel drills and lathe tools.

Hi i’m a tooling engineer for Mitsubishi Carbide in the UK. Most of the advice above is correct. You can cut lower grades of stainless with high speed steel tooling although it will wear out quite quickly. If you are only prrducing a few parts it should be fine. If you have more to make sintered carbide inserts are the way to go. We have loads of different grades of insert depending on the exact grade of stainless. If you let me know what standard ISO turning tools your guy has I can send you a couple of samples FOC.

So the time it takes to regrind your brazed tip every time you loose the edge is not costing time?
Which in reality has a cost!
Rough out with an old tip then change for new edge for finishing cut, as easy as that!
TPMR insert £3.50 approx
How many general or precision engineering workshops use brazed tip tools?…………. Not many I would say!
Q. For OP… What application do you need your bushes for?Posted 4 years agojohnellisonMember
304 st/steel every time. Best alrounder going. Don’t need any special tools, in fact I find HSS drills go through it better than Ti-Nitride or cobalts. No special tools for turning either.
316 is VERY expensive compared to 304 and it’s a lot tougher (as opposed to harder, different property), so harder on tools. Oddly 314 is harder than both yet it’s a lower grade than 316.Posted 4 years ago
For the -ve among you..The lad has been with us for years and we keep his rent really low.We even drop it for him when the work is slack.He,s a mechanic but is very good at all things metal.Anywho all sorted out now and he,s making up a few for both my full sussers.Obviously i pay for the materials and tools.Posted 4 years ago
