For sale is ONE KoolCarb Carbide gun drill. This is a coolant through drill with a carbide insert (brazed in) made to drill 1" diameter holes in hard materials such as dies.
Came from a bankrupt die prototype shop and looks to be in excellent shape. Check out http://www.drill-service.co.uk/Product.asp?Parent=Straight+Flute&Tool=385, they ask about $400 for a shorter one. These are rare and very valuable drills.
