High-tensile steel

[magicniner]

what sort of cutting speeds would you use with HSS and carbide cutters to machine it?

I usually take a couple of roughing and finishing cuts while setting up my DRO for a new job and you get a feel for this kind of thing after some time cutting a wide range of materials.
If in doubt I consult Machinery's Handbook, if you don't have a copy I recommend you shop for one on Amazon or eBay as they're a brilliant book for reference and for general leafing through and reading, you'd be surprised what you discover while reading any given copy of Machinery's Handbook, I have a copy from the 1950s and one from the late 1980s

Thank you very much, to everyone


Could we say that body cutters are in high-tensile steel? What sort of cutting speeds with carbide general purpose tips would you use to cut it? could we say from 10 meters per minute to 20 meters per min, do you use coolant? I know most of the time air is used on this kind of steels... Thank you very much again your support

High tensile steel is a very general term. More specific, but still general terms would be Low/Mid/High Carbon steels.

For speeds/feeds you really need to know the exact grade and current state (i.e. annealed, hardened, tempered - bigger sized bars in certain grades can have varying states of hardness/temper as you move from the perimeter to centre).
A good start for speeds/feeds, is to use a speed and feed calculator, which should give you some reasonable numbers to start with. A good online calculator is FS Wizard - http://zero-divide.net/index.php?page=fswizard

What kind of body?

[hoezap]

the body cutter of any indexable cutter

[komatias]

I would say they are engineering steels. No need for high tensile properties.

[magicniner]

the body cutter of any indexable cutter

Cutter Body means "the body of a cutter"
Body Cutter means "a cutter for use on a body"

I asked the question because even the context in which the question was asked left the meaning ambiguous and I wondered if you might be referring to the kind of sheet metal cutters used by panel beaters and body workers.
