@amw1814420 What kind of industry are you in that requires so much tool steel?

Can you send a link on some recommended speeds and feeds? Always looking for good new machining sources.

Still working on More materials to choose from. Just 4 at the moment. What kind of Steel do you guys want to see?

Increasing to 10 for now. Then hopefully 20 and beyond.

Also James what do think of a hole position calculator? and a max material calculator.

There is only on issue I see. I would have to do a lot of research on turning, boring, and grooving inserts. I have a good feeling that each manufacturers insert recommended speed and feed varies. Endmills do not vary as much between manufacturer. If the top 5 to 10 insert manufactures insert were similar in s&f recommendation I could get a lathe calculator going. Do you know the most popular lathe insert manufacturers are? I need a starting point.

Is there any other functions you would like to see?

Is there any other function you would like to see in this website?
