Shoze 2PCS Precision Blocks Hardened Steel Blocks 0.0002'' Engineer Ground Hardened 23 Holes Engineer Blocks 1''x 2'' x3'' for Milling Machinist Lathe Tools

These blocks are very useful, with some threaded holes . the Price is very good for a 4 pack and of course accurate, with a handy size. Thanks

I bought two packs of these and I am very happy.They are precise and 100% square, I checked using more than one high end square. They are well oiled so will need a little clean up, but it means you have a very well made set of blocks with no surface rust.I've used them to quickly check my table saw and chop saw are running square, and on my pillar drill to hold pieces whilst drilling. They work perfectly and a for the price are a bargain (which is why I bought two packs).

Really well made for the price and dead useful on a small mill

Good product at a good price

It's very good quality and accurate and a great price.

Great and very accurate for what need for

I purchased these 1 2 3 blocks after seeing them on YouTube and if you want something to check your other tools or corners for square then these are for you. I cannot fault them in any way and at a very reasonable price.

Not the most accurate blocks, but for the money you just can't beat them. I use them for Balsa modeling mostly.
