Prodotto consigliato per hobbistica.

Measured the blocks with my Mitutoyo calipers and every dimensions came out within +/- 0.0005 (half a thousandth). Was not expecting that level of accuracy for $20. Surface finish was good and no issues with burrs or sharp edges around the holes or on the chamfers as I read in reviews for other manufacturers. Havent tested the threaded holes, but I personally dont intend to use them. Came with protective oil. I cleaned off for use but applied a light coat afterwards with the rag-in-a-can method to keep these from rusting over time. (Ive seen some people complain about rust, but unless your tools are made of stainless steel you need to take some measure to prevent rust.) Highly recommend. Worth every penny.

Be warned, it comes DRENCHED AND DRIPPING with oil. Open with care away from anything you dont want stained.

No specification for accuracy provided in listing. After knocking down any burrs with a set of precision ground flat stones dimensions as measured by tenths micrometers were within 3 tenths, over on the 1 side and under on the 2 and 3 inch sides. Not bad for the price.

The blocks I recieved were dead on accurate on all sides and nicely machined. Great item and a great price

Bought a bunch of these over the years and its literally the same product, which is good! True and accurate; I use these as glue reference setups in production of my workshop. Cheap and last a long time. Just keep them regularly maintained and they wont rust.

Well packaged to prevent rust & damage in transit. Measured within advertised specs for accuracy. A great little bargain.

Metal? check

Holes in the blocks are threaded and I love the weight in hand. Such a convenient and useful piece of steel.

Measured against a Starrett caliper and it is accurate to the caliper’s resolution of 0.001” in all dimensions. Maybe not the right tool for it but I used the caliper’s ground jaws and it all sides seems square.
