Many moons ago I remember using Pop's center punch, and as I recall I was using it to align 2 pieces and I was hammering on it from the side, hence I broke it. Well, it's about time I fixed it. To start I just ground the end of the punch flat again, then chucked it up in my drill and ground the point back into it. The critical part is quickly quenching the punch after you going the point, this rehardens the tip so it'll maintain its point. Otherwise the heat from the grinding softens the metal.

The RENNSTEIG Automatic Center Punch (Art. No. 430 130) is perfect for preparing drillings. Due to the adjustability of the impact force and the self-impacting precision design of the center punch, no hammer is needed for center punching on metal and other surfaces.⁣ ⁣ #constructiontools #metaltools #centerpunch #tooldesign #toollove #industry #qualitytools #madeingermany | Knipex
