My boss turbo housing is not drilled for the support hole. I took the housing to my machine shop to have it drilled and tapped. Unfortunately my machine shop can only drill it but not tap it. They said I need carbide tap since it is stainless housing. They broke their high speed steel tap while tapping it. I can't find carbide tap anywhere. Anybody know where I can find carbide tap or anything that can tap stainless steel?
Thanks
