Review: good - good
Review: I have to but one of these every decade or so. They occasionally wander off to environs unknown; likely someone else's shop. General tool is the standard others copy bought my first General Tools automatic center punch off the rack at Sears over forty years ago. I have never broken one, they just evaporate. I have three models currently this one is the best, the version with out the replaceable tip works is good, and the narrower pencil version is lighter to carry for occasional use.

## Features

- STEEL BODY: This must-have pre-drilling leather punch tool can scribe, stake, and prepare nail and screw holes. It's easy to use, and the one-handed spring tension adjusts for light or heavy strokes and marking on wood and metal surfaces.

## Questions & Answers

**Q: Has anyone tried breaking a 1/4" glass plate with this? Did it work?**
A: If you wish to break plate use a hammer, this will work on tempered glass if any thickness

**Q: Anyone use one of these to extract broken bolts? Is it strong enough to get a punch for a bit? Looking to remove a bolt inside my engine block.**
A: I dont think john p actually ever tried this. Dont know about the cheaper utility version but the big #78 which Ive had for 15 years will put a divot in anything short of a broken drill bit. Ive removed broken taps with it a few times by softening the metal around the tap then repeatedly punching the tap in reverse. This tool has amazing power. That said, mine misfires about every half dozen clicks but doesnt bother me considering how well it works.

**Q: Do i need any machine to use this or take off the bike bolts**
A: I dont understand the question,this is a center punch,not a take off tool.I used mine once,and the tip broke off.It was a piece of junk,so I don't know.If the bike bolts are rusted,or welded,on it seems like to me you are going to have to cut em off.

**Q: Would this work well to get a starter dimple for unibit/step bit when going thru metal studs or panel boxes?**
A: It might. It works better if you drill a starter hole with a twist drill first. Usually the step-bit and unibit drills don't have enough of a point to start in the dimple that the center punch makes.

*by S***U on 26 December 2017*

I’ve got Starrett auto centre punchers and these general auto centre punches and obviously these are not as good, infact I purchased the steel option punch above and when it came there was rusty oil coming down the bent shaft, yes that’s right, it came bent. I had to strip it down degrease it and get rid of the rust which was caused by the adjustable spring on top and I also complained and and Amazon have sent me a replacement and the replaceable tip on the first one came half hanging off and after inspecting it the threads were stripped so it just spins in the hole so I’ve used blue thread lock which has sorted it out. My point is how did this pass QC (Quality Control) as it’s a mascot to this companies general workmanship and craftsmanship and pride so shows off there handy work. If this is a image of who these people are and there standards then it give people reason to belive that all of there tools are in this decrepit state or are of poor quality. It’s the Chinese ethic of quantity not quality as with everything they peddle to us westerners ! Crap !
