WEN 10423 3 x 2 x 1-Inch Steel-Hardened Precision 123 Blocks, Two Pack

Dont know why I didnt get these sooner but when I got them, Ive used them in several ways, i.e. truing a table saw blade, setting dado heights, etc. Their uses are endless whether its the 1 2 3 sides ,or any combination of them. Simple, easy to use. A mere block of metal with so many uses.

Updated: Crude and not imperial. Mitutoyo micrometer 0.98455x1.9695x2.9530. Anyone look at these numbers. The blocks that were sent as 1x2x3 blocks were in fact 25.00mmx50.00mmx75.00mm. Still crude threads and a few chunks that interfere with thru bolts.

They do what theyre supposed to. A 3/8 16tpi bolt threads easily but will NOT pass through the untapped holes (this is a correct design.)

Accurate and makes setting things up easier.

Im impressed, came out perfect vs a dial indicator on a granite top with no discernable variation, perfectly flat.

The blocks are very accurate however I ordered inch blocks and received metric. Throwing calipers on the block shows the dimensions are very accurate.

Great little set of 1 2 3 blocks for the price. Measured within about a thou on length, width, and height. They were out of square by roughly 2 thousandths. The blocks were not machined as a set, so they varied slightly.

I ordered 2 blocks.

Al primer viaje, solamente con el manejo de la maleta en el aeropuerto, el arco llego doblado, lo que hace que muy difícil volverlo a cerrar y complicado para abrir

Great quality for the price.
