Designed to be used with most standard gun drills that have a 3/4″ shank (which is standard). The gun drill itself can be found used on eBay or new on sites like MSC. This handle adapts those gun drills to be used by hand. It has a 3/4″ bore and on the backside of the handle is tapped for 1/4″ female NPT. I attach a ball valve and my air compressor quick connect fitting to the back of my handle.
A gun drill is useful for a starting hole in hollow form and long bores in any project (such as a lamp base, etc.).
Gun drill not included, only handle.
