Starrett819 Hinge-Locating Automatic Center Punch With Adjustable Stroke, 5" Length, 5/8" Diameter

Quality item that will last for years.It dose what it was designed to do, it just works.No more swearing up the top of the ladder when it fails to work again!

This is a precision engineered quality tool and does exactly what it's supposed to with very little effort. It's perfect for when you need to put a mark in a very difficult to reach area too. I have a much much cheaper auto punch and it requires much more heft to work. The Starrett ain't cheap but as always you get what you pay for.

I have used this on a number of occasions and find it does not always put mark dead centre. Its not as full proof as the description and price suggest.

Very easy to use and helps to be accurate on drilling
