Fish tails are great for sharpening tooling. Even the cheap ones work. But what I love about this Gage is on the backside it has a thread cutting depth chart. great when I'm cutting threads on the lathe and don't have my handbook around.. Nice and thick, great Starrett finish.

It does what it's made for and always quality from Starrett. Numbers not jumbled or unreadable like cheap brands. Would buy again.

All the markings are accurate and clear, but the fit and finish aren't what I was expecting for the price. There were some artifacts left from punching the fish tail out of the sheet which I wasn't expecting and should not be there. It's still a nice tool, but not deserving of 5 stars.

All three of the 60 degree references have either stamping marks or small burrs in/on them. This is hardly the precision tool I would expect from Starrett. This is the quality level that I would expect from an imported tool a quarter of the price I paid for this one. I'm very disappointed. I guess that precision and quality are now just a thing of the past, regardless of what you are willing to pay.

I buy Starrett because it is a US company and pay the higher price for US manufacture. This tool along with several other Starrett products do not state that they are made in this country, leading me to believe otherwise. I am disappointed. I should have bought a less expensive center gage as I do not know the origin of this one.

Typical quality I've come to expect from Starrett. It's accurate, no burrs, feels pretty sturdy. Not much else to say. It's a flat piece of steel for measuring/setting angles.

The quality is worth the price. I first ordered a cheap gage and found that it would not work because the apex of the angle cuts did not have any clearance at the points.

This is the defacto standard for thread cutting on a lathe. I use it to set my tool and to check my TPI. Well made, has stood the test of time.
