Please, i could use some more of these also.
You need a carbide tool grinder. Then these are GREAT for making right or left hand cutting bits, just like you do with HSS. Can also make custom form tool bits. But normally use 3/8 or 1/4 sizes here. I mount a green wheel with 10 degree relief on the left to ruff out the shape and then a diamond wheel with 4 degree relief for final hone of the edge.
BTW, these go for pennies on the dollar at commercial shop auctions. The big boys don't use them anymore.

I have never seen them used as is, always modified, the only relief is on the front edge.

I have a lesser number than I thought, I had sold some of them at a hobby machinist club get together, but I still have 10 of them:
7 ea Carboloy D8 (1/2" square) 883 grade
3 ea Carboloy D8 (1/2" square) 370 grade
I would let them go for $5 each
I also have a number of 60 degree pointed tools, some left and right handed 1/2" square tools and some misc. 7/16 shank tools, prices would be about the same as above. Also I have a large quantity of triangular negative rake inserts and other shapes, some in boxes, and some loose, prices would be quite affordable. Shipping would be by USPS small flat rate boxes.
