35" 1/4" diameter shaved thin back 24" with a 1 3/4" 75° flag. This tool is designed to go between the waffle panel and the outer skin on aluminum hoods, however it will work many other places like middle door braces. It is a very flexible tool with hard drive that will work in many places where a small diameter shaved flexible tool is necessary. Behind middle door braces, hard to access 1/4 panels, fenders, and much more. A great and necessary tool for every tool cart. This tool is a must for no drill dent repair.
