you need to drill it pretty slow Gary


plenty of lube and keep the drill cutting


best bet is a piller drill so you can get the pressure on it too

If you really want to do it then a titanium nitride coated solid carbide bit is the way to go, but as most things to do with SS, milling, grinding, cutting, drilling you can better have a look round for a small workshop in your area and talk to one of the workers, most things can be done for a fiver in their lunch break. I TIG weld SS free for bikers. :wink:
