findmall 1 x 2 x 3 Inch Blocks Matched Pair Hardened Steel 23 Holes Accuracy 1 2 3 Block Machinist Milling

I’m using them to help me square off angles and hold things in place as I build models. I had to give them a thorough washing first, since that’s not what they’re designed for, but with all the grease cleaned off, they’re the perfect thing.

They perform as described. If you have never used these tools then you would not understand that they are like having multiple “other hands” lol. I will recommend these to anyone getting into somewhat precision metal working. These things are spot on with respect to dimension and thread sizes. Good buy.

Bought these for a beater set. They work great for general set up. These are by no means ultra precise tool and die grade blocks, but they are excellent for general shop use. They all passed a caliper check, but don't expect a lab grade product.

Blocks appear to be accurate enough for my use at a low cost.

spent about 30 minutes getting crud and metal shavings out of the holes. Otherwise they are pretty solid appearing. update: got some of the greasey crud on my shorts. There is a lot more crud in the holes than I originally noticed. second update: spent a good amount of time cleaning them up, and they are great. I was curious and looked at prices on other 234 blocks, and realized these are only cheap cause they don't clean them up for you.

Solid 2-3-4 blocks that measured dimensionally correct to .001" across all sides using a set of Mitutoyo 6" calipers. Came packed in enough preservative to survive several decades in a warehouse. No way they were rusting anytime soon.

Great value. I always wanted a set and now I have 5. Great price. Each set is individualy boxed and each block is wrapped in oiled paper.

I measured these on a granite surface plate using a height stand with a .0001” indicator attached, all calibrated equipment. All sides measured parallel within +/- .0001. Flatness was virtually perfect on the matched pair. Others have mentioned the countersinks are pretty rough on their surface finish and I agree. However, all threads and faces are burr-free and function correctly. Purely aesthetic, but considering the price I can’t complain.

It works good for me, thanks

I have a small combo hobby unit mill and lathe, I bought these for carpentry use, and some automotive use machining, The .0002" Accuracy can be considered perfect for this application!! And the price is VERY reasonable!! My old 0-1" and 1"-2" mics show those two sides, to be extremely accurate WELL within the specs advertised. I am not bothering to keep them in matched pairs as for my use it will not matter. GREAT product!! Very good price!! It's an advantage you don't have to store these daily work-horse tools in bubble warp, USE them often!!

Excellent for mini crafting. Very happy

Well made blocks, very nice addition to my tooling.

They seem a good value and work good
