Mick B1, not a criticism but spiral flute propels swarf upward through finished thread whereas spiral point propels it downward out of back of thread, preferable no?

Circlip, I was one of those of whom you speak & always regarded my apprenticeship as the price I paid to learn a skilled trade, ie skilled manual turner, setter, chargehand, automatic lathe setter, operator of CNC lathe the size of a Transit van & the rest of my adult life setting & operating every shape, size & sort of CNC machine, back in the day our mantra was " I'm not on the YTS ( Youth Training Scheme ) this is my expletive job "

call me old fashioned but I never wanted to wear a collar & tie for a living.

Maybe I didn't look long enough, but I saw they were getting a continuous and thought they wouldn't want it birdsnesting on the eject side.

Maybe I didn't look long enough, but I saw they were getting a continuous chip and thought they wouldn't want it birdsnesting on the eject side.

Philip , I think you will find they are walnut shells commonly used to tumble parts.
