Groz 01415 12" Spring Outside Caliper, Matte Finish, with Solid Nut

This replaces a vintage set of outside calipers that were finally worn out after at least one lifetime of use before I got them.The Groz outside calipers feel very solid and works easily.First of all, the edges are all rounded -- it feels great in the hand, and no sharp edges. Metal is polished to a medium satin and the tool came covered in a nice coat of oil, so no rust. The adjustment nut knurling is sufficient for grip and not sharp - the screw itself is fine enough to get a snug slip-fit on parts (accuracy), the tension on the spring is firm but not overly tight. And the size is perfect for a shop apron pocket or just to live on the pegboard beside the lathe. Speaking of which, I might get another - one for the wood lathe, one for the metal lathe.very nice tool that should perform well and last.

I needed an inexpensive tool for wood turning. These work great. Easy to adjust but holds a set dimension well. They are well made and the tips that are key to accurate dimensioning come together precisely and are repeatable. Not for ultra precision work but great for the woodshop. Reasonable cost.

Good weight. Sturdy and dependable.

The two tips are not ground evenly, and that causes a slight overlap instead of meeting perfectly; but for my purposes and the price, that is acceptable enough. Might be worth sharpening if you have the tools. Build quality is decent otherwise.

I bought a different one of these at first that was crudely adjustable and I had to send it back because it was inaccurate. This one is finely adjustable and worked perfect for the odd ball measurement I had to take that a tape measure wouldn't do the job for.

Just what the doctor ordered. I needed a tool to measure the diameter of different sizes of pipe to make pression brackets to join them together.

Nice product, fast shipping, well packaged! Very pleased with this product, should last a lifetime! 👍

To get 3 calipers at this price is a great deal. They aren't the highest quality but they work well. I like this type of caliper because you can drop them over a piece on the lathe while it's still spinning, no need to turn the machine on and off every few seconds. Just turned 18 spindles for some stools, ends needed to fit into 5/8ths hole snuggly. Set these to just a bit over 5/8ths and then used a dial type caliper to fine tune. Dial caliper really can't be used with machine on, don't know if it moves or not. Great item especially considering the price.
