I doubt it. It is probably somewhere close to 45 degrees or 30 degrees, but I doubt even the chap making it was particularly bothered about the exact angle. I suspect that the angle will be too shallow to make it possible to grind a tool that isn't undercut. Maybe keep the boring bar for boring and get something like http://www.ebay.com/itm/141967673097 for threading? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
