I'm looking for a general purpose external grooving tool kit (for lathe use) that might contain a variety of inserts for different groove widths related to standard retaining ring/e-clip thicknesses. I'm a one-man prototype shop, and most likely one insert of each size from about .020 to about .060 with the appropriate holder would work very well. Anyone know of a supplier that has put such a kit together? I thought I had seen one a couple of years ago, but don't seem to find anything like that now in my travels across the internet. Thanks --
