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

After 1-2 week of use.

This is a nice punch. Would have given 5 stars, but the first time I used it, the punch did not reload. I took the unit apart but found nothing I could see holding the spring. I banged it on the table and the spring released. After reassembling the punch worked perfectly and reset every-time.

Wasnt sure if I could use this with not much hand strength; but this was easier than I thought. I kept losing the little pre-drill screws. This was a great find. And TWO for the price was even better.

Love it

Neither item work directly out of the box!

I really like these centering punches. Ive been working on a project that involves drilling dozens of holes in mild steel. My old punch (another automatic) never left a satisfying dimple to start a drill bit. It would leave a mark to line things us, but it wasnt deep enough to ensure that the bit wouldnt wonder. Well not these punches! The point on these punches is sharp and suepr hard. The spring has a terrific punch to it and is strong enough to get a good start in any metal or wood surface. My drill bits of various sizes were always right on center following the dimple from these punches. Highly recommended.

If you have to drill holes in ...... you can simply start drilling and hope the drill bit actually goes in straight. On metal or on rounded surface you know the drill bit will dance around before catching and scraping up the surface as it goes. These center punches are spring loaded so you simply place it where you want to drill press and it leaves an indent keeping your drill bit centered and straight. A must have for anyone working on metal or plastics. Good quality tool which when you learn how to use you wont ever not want to be without.

Easily adjustable striker. Works perfectly. Built well.

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.
