Supples in matched and numbered pairs, these V-Blocks are manufactured from
high quality castings
properly seasoned against distortion and are accurately machined square and
The previous review stated that the V surfaces were not ground but my set was. I guess they skipped a part of the process or QC entirely. The top surface, the V and the bottom were ground on my set. I took a file and broke all the sharp edges. Noticed by accident that the V grooves match only when the blocks are placed together in a specific way, so I took a letter punch and marked the unground surface of each block. This way if I need to use them both at the same time, I'll know how to place them. Also filed the surface that I punched an "X" on to make it flat again. The metal is soft enough so handle accordingly. Good buy, would recommend.
The dimensions listed here are completely incorrect. I measured the blocks to be 3.007"x1.307"x2.442". The blocks are only ground on the top and bottom surfaces, not the rather important surfaces of the V themselves. They are not numbered as said in the description. The castings are quite poor quality, and porous enough that one of my blocks had an air bubble in the bottom surface, even present after grinding. The price was affordable, however I would still give these no better than a C- rating.
