I know that, my teacher didn't thoughLOL yea i know that but it is a lubricant and coolant when your backs against the wall
Who suggested that crazy ideaIts not a ant flame thrower too![]()
I think I was given some bar with coloured paint on one end, that will tell the grade if I'm not mistaken?Any low carbon steel with sulphur in such as EN1A cuts like a dream. If you increase speed and/or feed with HSS tooling too much you'll be spending more time regrinding the tool than on the lathe cutting with it.

The radius is key to a good finish with HSS.
It would if you could find out who supplied it, the problem is that different suppliers use different colour codes.I think I was given some bar with coloured paint on one end, that will tell the grade if I'm not mistaken?
I'll chuck it out then. I only used it as I needed 13 mm diameter so I had the choice between this, some rebar or some 1 1/4" bar.
Has anyone turned rebar before? I did a couple of days ago and once all the ribs were gone, it machined quite nicely.
What is considered a heavy cut? I had usually taken no more than 0.01" (off the radius) on steel but I was playing yesterday with this tool on good steel and was able to comfortably get 0.025" (I think it was 0.004" per rev feedrate) which I thought was very impressive.
