Auto centre punch
Item arrived as advertised and I’m very happy with it Thank you Good quality

Excellent punch, strong recommendation from me.
As with other Starrett products, a well engineered punch. The "automatic" bit works just fine, leaving a significant mark in wood or steel. It is smaller than I expected (my prejudice?) but works perfectly well. Wholly recommended. I believe the tip is replaceable too - should it be needed

Well Made
Does exactly what is expected - automatic punch with an screw adjustment for the stroke / impact. Starrett is a trusted brand, and this tool is well made and should last a long time.

Works well. Just push down and you get a nice centre punch. Why haven't I had one of these before?!

What happened here Starret ????
Starret have always been associated in the engineering world as manufacturing great quality tools and equipment................... BUT WHAT WENT WRONG HERE......... ?? The punch is made really well, really nice quality as expected BUT the actual task of performing what its designed for is a joke............. I used it on a piece of timber and it hardly marked it ? it would definately not even scratch metal......... oh dear Starret, you let me down... I have 3 other auto punches all set to use for different tasks and they all function as intended. This is like a wet blanket when it comes to performance...

Lovely bit of kit!
Small and compact, still made in Germany, decent punch, good value when you consider the quality!

It is nicely made and a conveniently small size
I've struggled with cheaper centre punches and their hit and miss action, even when they were brand new. This centre punch was certainly not cheap but it does work perfectly and I've yet to experience it misfire. It is nicely made and a conveniently small size. There is sometimes a good reason why some things are more expensive...
