Pixman, When You Get A chance

I'm reading this on my phone, so I can't see the pic as well as I'd like but is that a mechanical chipbreaker on the Aloris AXA16 - TPG 322 holder?

Yes, a mechanical chip breaker, it is slotted to allow some adjustment. I pushed the chip breaker as close as I could to the cutting edge, as the chip breaker is also the insert clamp, this offers the most support to the cheap insert. Thus leaving the least amount of the insert exposed. The Aloris AXA16, is an expensive tool, which is somewhat strange, an expensive tool and a dirt cheap insert. While I have used it quite a bit in the past, it now resides in the storage drawer, I do pull it out from time to time. I get better results with other insert/tool combinations.

I have a couple of holders for TPG/TPU inserts too, with the mechanical chipbreakers. I only use them for special applications because chip control is so "iffy" with them. When I do use them, I have some Valenite TPG321 grade 610 cermet inserts which leave a beautiful finish in crappy steels when carbide just won't.

All those tools have a place, and the MCLNR and DWLNR holders would be my primary "all around" choices.

Thanks for all the info, Ken.

I have cans of spray paint for that very same reason
