Tekton 6580 automatic center punch
on May 16, 2014
As a retired machinist with over 23 years’ experience, I’ve owned a few automatic center punches before. For professional needs, where the tool will be used often, the Tekton 6580 would not be the best choice.
I found I had to keep the center punch set to its maximum pressure for common, soft materials such as aluminum, 1018, and 4140, (in it’s annealed state). In addition, I had to repeat the punch application 5 times or more before I made an acceptable dent that would keep a tool such as a twist drill from “walking”.
The point on the Tekton 6580 appeared to be fine after several uses. I don’t know what material they used to make the punch itself, but it seems to be holding up okay. That said however, because of such a low-pressure trip-action even when set to maximum, I would expect the point on the punch to hold up for some time.
Though much more expensive, a center punch like a Starrett model is capable of placing a good, deep dent with just one application. In fact, if you set a professional automatic center punch, (such as the Starrett model or even one made by General Tools), to its maximum pressure application, it would take impressive amount of pressure and effort before the punch would actually trip!
I gave the Tekton 6580 Automatic center punch 4 stars because I’m not able to select 3.5 stars which would’ve been my preference. The tool is made well and the price is right for its performance.
