Why New Vista’s TG Guns are Replacing Manual Gaging and Hand Chasing

New Vista is well known for its large offering of automated thread verification and chasing equipment. But not every application requires an automated solution. If your volume is limited, a powered handheld device may be the answer. If you are still gaging or chasing threads manually, it’s probably for one or more of these reasons:

  • The guns you have seen are too slow.
  • The gage / chaser tears up the mouth of the hole.
  • Guns you have tried jam if you hit the end of the threads, and you can’t back the tool out.
  • Tool breakage is frequent

The new TG guns solve all these problems, and they are inexpensive as well. Generally you can figure out that a TG gun will be 10 to 20 times faster than manual gaging / chasing. In high labor rate countries the payback in labor savings can be as short as one month. In low labor rate countries, payback might be six months, which is still very good. And you can now get started with a TG setup for as little as $1,650 USD.

Watch this operator gaging M6 holes in air intake manifold: Click Here to Watch Video VTG7. He is using a New Vista TG-3B gun here, and is able to make a 2.5-second hole-to-hole rate. These are deep holes, 15 threads each. The torque setting is dialed in with this gun, and then locked there. The gun reverses out automatically upon attaining the correct minimum thread depth; and the green flash confirms it.


  • The gun never jams when it encounters a short thread (the holes with the red tape).
  • The gun doesn’t hesitate, crossthread or hang up at the mouth of the holes.

Even inexperienced operators can quickly learn to use these guns effectively.


If you have a limited budget you might prefer the TG-1A or TG-2A guns. They cost less. These don’t reverse automatically, so you watch a stop collar to determine if you have attained depth. Watch these videos: (VTG4), (VTG5) and (VTG6). The breakaway toolholder that you see in the first video guards against tool breakage and also permits fast tool change.
