Thinking about making one of these from some spare HSS bar. Don't know much about metalwork so can you drill HSS with ordinary (TIN) twist drills or do I need a cobalt ?
Idea was to drill a nice neat hole of the desired dia. then do the rest on the edge of the grinding wheel. If it works, might even try making a beading tool same way. Or is this likely to be a waste of time.
