Recommend some 'standard' carbide inserts
I'm making some new toolpost blocks for my Phase-II QC lathe toolpost, and I want to make some that take carbide inserts directly.
Aloris makes some, it's basically the standard dovetail block with a nose machined to take one form or another of replaceable carbide insert. So instead of buying a $25 toolpost block and clamping a $45 carbide lathe toolholder in it, I'm making a one-piece block.
However, I know little or nothing about replaceable bits or carbide. I have a few that I bought used or traded for, but I don't know the designations of the inserts, how to properly measure them, or how to order more.
I'm making these blocks from scratch, so I can have them take any insert I want, within reason. So the question is, what would be a good selection of "standard" shapes and sizes to go with? I want a common size that I can get from a variety of suppliers, and will probably still be around years from now.
I'd like to order a box each (10 pieces) of, say, three different sizes or shapes, plus the holddown bolts, screws or clamps, and then machine the toolposts to hold them.
I'm thinking a triangular insert first, in a standard size I can get in a common variety, including chipbreaker or flat, and perhaps in varying nose radii.
Then a trapezoidal insert, or maybe a long diamond, and possibly a round, to do an inside radius on parts.
Could someone recommend a good, standard, size and style for me? It's an 11" lathe and I'm using an AXA-size toolpost. The blocks can take up to a 1/2" tool. The largest carbide tool I have is a 1/2" dia. boring bar that takes a triangular insert about 9/16" on a side, held down by a center screw. That's a good size, but how do I tell what kind or style insert it is?
Thanks.
Doc.
