WTB 16mm X 5mm woodfuff key cutter.

[Froneck]

McMaster sells metric woodruff keys but not the cutters. They do sell a woodruff metric key that will require a 16 X 5mm cutter. I'm not cutting a woodruff key slot, 5mm is slightly more than 3/16" available in a 5/8 diameter cutter. Better yet will be a 15/64" wide 5/8" diameter woodruff cutter but that's not a standard size.

Not sure of your application, but can you just set over a narrower woodruff cutter to get the width you want? I've done that many times before (screwhead slotting....).
