I’ve bought and tried multiple insert designs, shapes, sizes and configurations, lots of trial and error. Some I use on a daily basis, others I use once or twice a year, a few I tried once and relegated to the drawer, for a long sleep. Once they got blocked up, they stayed blocked up, I’ve bought numerous blocks from CDCO, a couple from PM, a few from Dorian and Aloris.
I have some that work great on aluminum and brass, but worthless on other metals, some that work great on steel and worthless otherwise, one or two that work great on stainless steel and titanium, but hardly stellar on anything else. I have one design that is fabulous on plastics, but probably couldn’t/wouldn’t do a half decent job on anything else, maybe wood.
I made a series of permanent boring bar holders, based on specific shank sizes. Yes, its a lot of blocks, but I hated to have to change tools and reset tip heights, during the job.
