2-Piece Automatic Center Punch, 6 Inch Hardened Steel Spring Loaded Center Hole Punch with Adjustable Knurled Cap for Machinists and Carpenters

I litterally bought these because they were the cheapest. I did some rersearch, and there were warnings about cheap automatic center punches, That the points weren't hard enough, or that the mechanism wouldn't work reliably. I figured that since I was planning on using on wood, the hardness wouldn't matter. I also thought that with two at least one would work.So here is my review after using it for a few weeks. First off out of the box only one worked. But after some more research and several dissassemblies, i found the fault and have both working now. the advice I didn't get from yu tube was to just swap one part at a time from the working one to the nonworking one until you find the problem. Once I did that the fix took less that 10 minutes.About hardness, I'm only using this on melamine particle board panels, and ply wood, But when I use it I use 100 strokes per day minimum. So softer material, more impacts. I'm seeing no degradation of the point.Overall I'm very happy with the feel and relability of these tools. They are making my job (installing cabinet hardware) easier and faster. I'd recomend them to anyone, using softer material, or anyone interested in getting familiar with this kind of tool

People stated that they failed to punch when pressed. Easy to take apart and a couple drops of oil to the parts. Snap them on a solid part then they work every time. break in is easy and they will work great. One of mine didn't work on the first try. Now it works every time as designed.

I've bought these before. Nice size, work well, and they seem to last

These appear to be heavy duty and well made. I have used a few times and am well satisfied!

Both worked out of the package and does place a center point; however, on any steel it doesn't hit with enough force to really make a useful mark/point. Works well enough on wood.
