If you are using an 80 deg diamond (CNGP431 or 432). the holder would start with MCLNR or DCLNR and the following numbers and a letter determine the holder and insert size. So, if you can find a tool holder that is described as MCLNR104A the holder would be 10/16" square or 5/8". The number "4" indicates the insert IC (inscribed circle) (4/8" or 1/2") and must match the last number in the tool holder ANSI description. The final letter indicates OAL with an insert in place, A=4" length, B=4.5", C=5", D=6" and so on.
Unfortunately I cannot find a 5/8 inch square holder for the 1/2 inch insert, so, you can simply mill a 3/4 inch holder down to .625 only up to the head end of the tool. Leave the shank a full 3/4" wide.
Purchase a tool from any source that is MCLNR124B or DCLNR124B and cut it down to 5/8" and get inserts for it from Fastenal. CNGP431, grade TN10U, (EDP#4164566) or CNGP433, Grade TN10U, (EDP#4164568). I just looked up the retail price for the inserts and they are $12.89 each.
Good Luck!
