Ohh, it's such a slippery slope this technology thing,
in the old days we used to believe there was no point in carbide threading tools except on automatics as the speed of manual threading was rarely high enough to use the benefits of carbide, but then the full form inserts came out and made it viable, but where do you stop? as threading with a full form carbide tip can be done at near to normal turning speeds so the next step is auto stopping the threading process or do you just go straight to CNC?
For hobby purposes I set the limit at HSS threading, to keep the costs down, if I need speed then it's no longer a hobby is it?
Having said that My aim is still CNC at which point I will re-assess my stand on carbide threading as at that point partial form carbide threading tools will be the minimum standard of tooling able to cope with the speed available.
