I like using collets to hold micro tooling it is a fast way to do it. I do have a knack for alignment though which ticks off my buddy in the shop who runs another lathe. I also have taken a old burned up 1" square holder and made one which holds 5/16 and 1/4 inch diameter bars. I use two small set screws to hold on the flats of the micro tools. I also drilled out two holes at an angle about 1/8 diameter to allow coolant. I use the plastic flexable coolant line to line up the nozzle to the hole and it usually works great. Also we take old cutoffs from boring bars and size the Id and then put in a couple of small set screws to hold the tool and since the cutoffs have flats they align nicely and takes the guesswork out of alignment. This helps an old man like me to cheat sometimes on alignment.
