Have to remove a broken stud on my 06 GSA , bottom bolt on the diagonal bar under the tank that then links to the rear frame and goes into the engine block , it snapped just below the surface so cannot get a nut onto it or weld , tried ez out and its been well soaked with penetrating stuff , have managed to drill 20mm out but still have 20mm to go and im getting through drill bits like their smarties .
read loads on technique etc and have started small and then large but the last 20mm is out of reach for my small drill bits and I really do not want to have to take the engine out .
If im lucky I will be able to retap to M10 but if not have next size on standby ,
whats the best drill type to use , hss , cobalt etc as this bugger has to come out at the weekend so I can put the old girl back on the road after a year out .
