Starrett Magnetic Base Indicator Holder for Test, Back-Plunger, AGD, Dial and Miniature-Dial Indicators - Complete Set - 657AA

A little pricey but worth it. Starrett product are top notch.

Used this with my Starrett dial indicator to re-gear the five differentials on my 2003 and 2013 Jeep Wranglers and my RWD 1990 Volvo 740. Excellent build quality, made in the USA by folks who take pride in producing very high quality measuring instruments. Not cheap, but will last a lifetime. Just like the old days. Quality is worth the expense for some things. This is one of them. The cheap POS from Harbor Freight doesn't even stay on the differential housing without shifting around. This magnetic base allows you to take accurate measurements of backlash, etc. It is expensive but saves you a lot of time (and the expense of eight or nine crush sleeves). If you only need to use it once you can always sell it later on CraigsList. These - around here, at least - sell quickly. I plan on keeping mine, however. I have already used it enough to have gotten my money out of it. Great magnetic base. Highly recommended!

If you can afford it , buy it. From the magnet to the rail everything feels like a craftsman tool (not the china brand)

He is very happy with this product. Arrived as described and works perfectly.

You can't go wrong with Starrett Instruments. I have been using Starrett measuring tools for many years and have yet to find a problem or calibration problem. You get what you pay for except Starrett tools are a better value because they last.

It's a starrett. What more can you say. It is always worth it to spend the money, and get the quality that will last for generations.

Nice instrument base

No way is the worth the price it’s a magnet for god sake. This is way China is cashing in on the US!
