I have two different parts (qty 3 of each) that need to be cut into eight pcs radially. (see attached drawing) Material is A2. To make holding the part easier, it would be okay to cut outward to almost to the edge and leaving a bit of material intact. Then after edm, "break" the part into 8 pcs and just buff smooth the edge. The 22.5deg in the drawing is not critical. Plus or minus 3-4 deg is okay. The part will be heat treated after cutting, if you have heat treating oven, pls quote also.
