2Pcs Heavy Duty Automatic Center Punch, 5 Premium Steel Spring Loaded Center Hole Punch, Adjustable Spring Impact Center Marker Scriber Tool for Metel, Plastics, Wood, Glass by karmiero

Doesnt work like it suppose to . Cheap made and no good to me !

The mechanism in both United are very difficult to work. Need to repeatedly press the unit down more than once to have the spring disengage and spring back to make the mark. Is is easier to just use a scribe instead of the center points that I purchased. Not happy with the product unfortunately. Thank you.

Cant say enough good things about this set of spring loaded punches. They work perfectly and like they are supposed to. The knurling provides a nice grip. Both sides can be unscrewed for cleaning and lubrication. You really cannot go wrong with this set. They are an excellent value. I have a Starrett at work that cost ten times as much as these two. They make the same indent on steel as the Starrett does. They even feel the same when used. I would highly recommend these center punches. Extremely useful tool to have on hand.

One didnt work at all and the other works kind of, but only 1 out of 2 times.

I used them to mark holes for screws on metal and they did not disappoint. Heavy duty and Precise.

IF yours doesnt punch holes, you have to open up the front part and change the direction of the spring. The spring that is closest to the hole punch part. For some reason the spring I received way put it backwards so it was catching on the mechanism inside and not pressing into the whole fully.

Its easy to use for pushing down but if you have a project which requires a push upwards or sideways, this tool isnt strong enough.

It seems like a bit of a stretch (i.e. that the spring impact will punch an adequate drill spot or mark). But it does! I tried it on alloy carbon steel...and it left just the right sort of dimple for the hole to be drilled. Its hard to predict how long the punch will maintain its point (before re-sharpening needed). I made a little holder for this useful too, between the drill press and the bench vise. ~ The Duffian

The tool is inconsistent. I rarely works as intended.
