Oudtinx1-2-3 Blocks Matched Pair Hardened Steel 23 Holes (1"x2"x3") Set Precision Machinist Milling

Nice blocks that I use to weight miniature projects while glue dries. Price is better than local stores.

As described at a fair price!

These are very accurate and extremely square. My only complaint was that they came packed in Cosmoline grease. I ended up soaking and periodically scrubbing them in 99% isopropyl for 3 days to remove the Cosmoline but they are great now and that horrible smell is gone.

The blocks I recieved were NOT a matched pair. The squareness and parallelism in the description may be true but the set I got had 2 thou variation between the two blocks on any given side. (Thats 0.002 variation) and seeing how I have trammed my mill within 4 tenths (thats under 0.0004) across 15", this set is worthless to me. Maybe when I get a surface grinder, I'll fix them but I went ahead and bought a MATCHED set from another company for about twice as much as these cost.I do NOT recommend these to be used as a pair to project a surface.

Blocks worked very well for my current project. Would buy again.

The blocks were received as advertised. Exactly 1" x 2" x 3". They were received rust free.If I ever need more, I wouldn't hesitate to reorder these. I raye these blocks 10 out of 10.

Everything came in a nicely seal box and was exactly what I was expecting. Arrived 2 days early too.

Overall the block are very usable, my only two complaints are one packing contained a heavy preservatives that require 2 cans of brake cleaner to remove, the second is the blocks are threaded however the none threaded holes are the same diameter as the threads. In order to use the threads to link the blocks together a threaded rod is required and can make it difficult to accurately connect the blocks. These will be primarily used for woodworking but this adds a little difficulty to set up.

No issues with these blocks.
