Thread: Machinist's / hobby machinist's

Yep, there is nothing than can't be done by HSS, especially by grinding the tool rake to suit the material. TC has only been commonly available since the 1960's. For the 100 years prior to that it was all done with HSS (including the engineering output of two World wars). I don't think you can find much fault with the quality of engineering up to and including WW2.
