I'm making some spare parts for a piece of computer equipment, and I know a few others do similar things, so I thought I'd risk asking here. I need some spare TCMT090204 carbide tips (small triangular ones) for lathe tools, and I've seen some labelled TCMT 731. I think this is one manufacturer's part number for that size. Does anyone know if that's the case, and what the proper ANSI designation would be? -- Pete Peter Turnbull Network Manager University of York
