    • Perfect
Style: Utility
I used to use these for working on lock cylinders at the car dealership back in olden days and they never worked half the time. I bought this one for something unrelated and it works flawlessly.

    • As good as Starret
Style: Steel
An Excellent general purpose auto center punch as long as you ensure the screw-in tip is securely tightened (screwed in, CW, as viewed from the tip) before each use. If you don't, there's a chance the tip will break off at the threads meaning you'll have to get a 'readily available', new tip. Bang for your buck? On Amazon, a new tip ~$10, a new tool ~$17. You decide. After successfully using the same punch for over 5 years, I broke my 1st tip a few months back. I tried several "Lo-Priced, Menards, Lifetime Guarantee" punches that only worked for 10-20 cycles before beginning to fail the auto-re-cocking routine. If it won't re-cock it wont fire. So I took the broken one back to the, store one town south of me and was handed a brand new one in the package. Before the 4th trip, I put the horse back in front of the cart and bought a brand new Central Tool from Amazon. The old one continues laying in my drill drawer needing a new tip. It sorta, but not 100%, reminds me of the old double edged safety razor gimmick where a Blade Mfgr gave you a free shaver then you spent the rest of your life paying for razor blades.

    • Works way better after cleaning and degreasing
Style: Heavy Duty Steel
When I first got this center punch I thought it was broken because it took way too much force to get it to "punch." I get that it's supposed to be a heavy duty unit, but it took both hands and most of my bodyweight to get it actuate with the adjustment backed way off. After reading some similar reviews, I took it apart, cleaned off the heavy oil it comes with and reassembled with a thinner oil and now it's working as expected. I can use one hand to center punch holes. ... show more

    • Not like the USA made unit from long ago
Style: Steel
This unit arrived new in the package but it was already showing rust on the tip. Internally there was dirt and grit and signs of rust. It doesn't operate as smooth as my old USA made version. Internally the design has completely changed for lower manufacturing costs, so the punch feature operates inconsistently as a consequence. I need 3 of them for a work project so I ended up buying good old used ones from ebay. I'll try Starrett next time when I want new. ... show more
