The 8mm bar i think is about 120mm long. It's a Mitsubishi solid carbide bar and it constantly surprises me as to what it can do. The sleeve material is quite hard and tough, a bit like stainless, but harder, and it seems to work harden too. But yeah... 70mm+ stickout, 8D-9D, and it was still happy taking 0.1mm cuts.What length is that 8mm bar? I couldnt see any so instead bought some carbide blanks and plan to make one up. The blanks are quite short though.
I was using my 12 and it was stuggling with 85mm deep. Its 150mm long, half is in the tool post.
At 25mm I swapped the 20mm bar - this never cut properly before, this time it works not too bad.
I like my Korloy STFCL bar too. I've had it cutting happy at 7D. Left hand or right hand doesn't bother me in the slightest, I just need to plug a minus into the DRO lol
I will upgrade that cheapy 12mm bar at some point, it's truly terrible, even with razor sharp polished inserts.
I have a 32mm bar and nothing in between 16 to 32, so maybe I need a 25mm at some point too...

I'm all about the solid carbide bar hype though. I know good quality steel bars are fine too, but you can definitely push carbide deeper
