HFS(R) Coaxial Centering Indicator Co-Ax Precision Milling Machine Test Dial CNC

This is a quality Coaxial Centering Indicator. This is the same indicator that other sellers have for $20.00 more. I just used this to center my rotary table. Worked perfectly. Got the table within .0005 in just a couple of minutes at most. I highly recommend this product and the price is way better than anywhere else I found it for sale. Shars' has this same indicator on sale for $64.00 right now + shipping. This may not do the job of a $400 indicator but it will get you within .0005 accurately and quickly/effortlessly. I checked the center with a quality .0001 indicator and this was right on the money. AND THE TIME SAVINGS IS ENORMOUS. Check out the youtube video of Tubalcain using this same indicator to see how you can save time also.

I like this tool. Easy to read, and works well.

This makes set up faster and easier because the dial always fades you, no need for using a mirror. I recommend this item for anyone that has to indicate using either bore or post. The price is reasonable for someone that would just like to see if it helps speed up operations. I think it is very accurate, and easy to use.

Used it today. How I lived without all these years I have no idea. Super easy to use and setup. Nice quality and price.

It's built pretty well. Has a tiny bit of wobble as it spins, but I mean maybe 1/20th of a division on the dial. It's very minimal and not a problem.The set screw that holds the feelers in stripped putting in the very first feeler with almost no force applied. The female threads on the unit are fine - that's made out of some mildly hardened steel. The screw itself is pot metal and lost its threads right away. I ended up drilling and re-tapping the female threads to 6-32 and used a screw out of an outlet cover. It holds much better and with much less chance of stripping now.The dial divisions mean nothing since there are multiple feelers that are different lengths and shapes. It's good for zeroing and centering, which is what I bought it for.-1 star for useless divisions on the dial.-1 star for a cheap pot metal set screw that took me half an hour to re-tap and find a tiny screw for.Still saved money over a US-made unit at $300-$700 and will do what I need it for.

I'm not a big fan of co-ax indicators since there's so much opportunity for errors. These get you within a few thou which was all we needed for the deep in a dirty hole HBM job I bought it for.It does look a little fragile and the adjustments are a bit hokey, but for the price I was expecting to have to fix it out of the box.I bought this for one job because it was the cheapest 1 day delivery option.

So far my indicator has done EXACTLY what the more expensive brands do,I'm just starting out in the machining industry and don't have a ton of money to spend,this tool has been worth its price so far

Main body wobbles while in use. It was machined off axis.
