Use a rotary broach. The cutters can be found at reasonable prices. The holders tend to be stupid expensive. Fortunately there's plenty of DIY info on how to build your own. -- Check out the vibrant tech community on one

Andy - The guys at the shop where I last worked beside used to slightly grind the flutes of a standard end mill, leaving (say) 6mm of flute length for cutting pockets. That way, the "higher up" flutes did not re-cut swarf, and thus deflect the tool, and there was no tool rubbing on the higher up

It won't be quite square but how about drilling small (1mm?) holes in the corners, milling out the centre and cleaning up with a small endmill? It will be at least as good as a typical 3/8-inch socket. > -Original Message- > From: John Kasunich [mailto:jmkasun...@fastmail.fm] > Sent:

You could mill a 10mm wide x 5mm deep slot in two rectangular bars, then silver-braze them together. Might not be strong enough, depends on if the OD is big enough to leave a reasonable joint area. Welding would probably leave a hardened zone and be miserable to machine afterwards. John On

I want to make some D1-4 cams for a 4th-axis project. These need a 10mm square hole (but 3/8 would be fine too). I don't think I can polygon-bore a square, it needs too much tool-relief. (I guess I should try, though). If I could find something like a 3/8" drive socket with no hole in it that
