A center punch is a hand tool used to produce a dimple that marks the center of a point, usually to mark the center of a hole when drilling, via Cool Tools
Hey, I’m Donald Bell and in this Cool Tools video I am going to take a look at automatic center punches. Maybe you have a cheap one like this for marking drill holes in wood or metal. I’ll show you how this performs against two higher end options. I’ve got Amazon links for all of these in the description.
So here’s what we’re looking at. This is a generic brass handle punch, the cheapest I could find. Costs around $5.
For $10, I bought the Neiko. It’s well liked on Amazon and has a different type of handle.
And for the top of the line, I got this $30 punch from Rennsteig. Highly rated. There are pricier options people rave about, but paying more than $30 for a punch is probably silly for most of us.
