All I can find are Hertels. Are those the ones you meant? It bares repeating that their website is really awful to work.
I am possibly eyeing a set of transfer punches from them. There's a import set for 22$ and a USA set for 64$. I can't really imagine they're much different from each other. Also I have seen bad reviews for every transfer punch set out there but I think people are wailing on them expecting to be able to use them to actually make the hole and not just mark it!
I have the Enco imports in metric and English. I've had them for more than 10 years, use them at work, no problems. A lot of the import sets have points that aren't centered well. The Enco's are fine.
The US made ones are considerably harder. If I used them every day, I'd probably spring for them.
I agree with Tinner,
I haven't seen the Enco imports but I do come across other imports sets and there's three possible issues to look out for:
1. The actual OD tolerance may differ from size it's suppose to be due to bad castings and low quality finishing, i.e.: There's more wiggle room than there should be? If you need real accuracy then your probably not dealing with imports to start with.
2. Like tinner said, the import points may not be centered correctly, I have found this to be the case because of what said above in #1.
3. Most importantly the US versions will have a much higher PSI than the imports which will make a huge difference in longevity.
The imported center punches ten years ago could have come from Taiwan which is significantly better than mainland asia. Recent imports can change widely in quality due to different factories being contracted to make them.
Problem is Enco only lists them as imports. Are they imports being made in Taiwan, China or India?
I will say center punches are a godsend when you need them.
