Tool Ejecting Draw Bar upgrade for SIEG style mini mills This is an upgraded draw bar bolt system for your SIEG style mini mill that saves up to half of the tool changing time and unwanted strain on your back and feet. There's also no more finding a pin hole to lock your quill or switching back and forth to loosen the draw bolt then hitting your machine with a hammer to get the tool out. It's simple to use and time efficient. This product was invented by Eric Richter, a small shop machinist looking to solve a very real problem in his own shop.
