Metric metic metic…. They cost a little more but they are actually metic and accurate. Although I’m using them for woodwork but seem reasonable quality worth a buy. I was sick of buying from other companies saying they were metric and when they came they weren’t

Simple and Brilliant
Now, if you are not a machinist or engineer you may not have come across 123 blocks before, but this is to miss out on something very useful indeed.123 blocks refer to the dimensions 1" x 2" x 3" - so if you are an imperial hater then sadly you are stick with the nomenclature. Much more snappy than 25.4 x 50.8 x 76.2 blocks......So, what you have is a block that is - or is supposed to be perfectly square in all dimensions to be used for setting machine tools. But, it has uses for the home user as well which makes some things much easier. In particular if you have a chop saw or mitre saw, you will know that the marks on the machine are more of a guideline not really to be used for accurate cutting. With a 123 block you can easily set up the 90deg cut in both horizontal and vertical plane easily.Likewise if you have a saw bench or a pillar drill the same thing applies. Easy way to set up your cuts.Now, as for accuracy? Pretty good I'd say. I tried cutting two bits of metal in opposite sides and then turned and matched them to see if they were the same, and they were. Near enough accurate for the home user for sure.The machined finish is very good and they come well boxed in a protective film of anti- corrosive waxoil.Overall a great value buy if you want to have an accurate setting up block.

Worth 10 stars
Perfectly square, my engineer brother checked these and they were the best he had ever seen, these were a spot on

Good
Thes look nice in there little wooden box

Excellent tool
These are as close as I can measure to parallel and the right size, within a couple of microns compared to some gauge blocks. Mine have M10 thread. They come in a wooden box that would benefit from a divider to stop them bumping together, and without bolts.

Terrible
The size of the blocks appears to be accurate (25x50x75mm) but that’s pretty much it.The holes are substantially off centre. To the point one can see the problem with a naked eye. To be on the safe side, I did measure the position of the holes and the measurements confirmed the problem.The corners of the boxes were done very roughly with too much metal removed unevenly from the blocks.Obviously, I have to return them.Unfortunately, I have to recommend buyers who need 1-2-3 blocks to buy another brand.

Incredibly accurate 123 / 25-50-75 blocks
These are Incredibly accurate 123 / 25-50-75 blocks - tested on calibrated Mitutoyo digital Calipers - will certainly be buying more!

Accurate for me
I use these for woodworking so don’t need the accuracy for engineering. They have been checked with the digital callipers and are with acceptable tolerances for me. They are used as set up blocks for fine tuning tools and have found them to be square as well as dimensionally accurate. These are metric which is also a bonus.

Parralelität <0.01mm bei meiner Stichprobe
Verbapckung war Top - konserviert und in Papier eingewickelt.Die Kanten sind zwar nicht hübsch, aber das ist mir egal, weil ich nur die parallelen (und rechtwinkligen) Flächen brauche.Ich habe die Parallelität auf meiner Granitplatte (Klasse 0) überprüft indem ich mit der Messuhr und Stativ alle Stellen in jeder Position die Abweichungen gemessen habe. Beide Blöcke haben einen Fehler <0.01mm.und sind von der Höhe gleich hoch. Die Messuhr und meine Messkompetenz waren daher die Beschränkung, vielleicht ist der Fehler also noch kleiner.Achtung ich habe damit NICHT die Rechtwinkligkeit geprüft. Das muss ich mir erst überlegen wie das geht 😁.

Einwandfreie Parallelblöcke
Lieferung wie üblich schnell und gut.Zu meiner Überraschung war die Verpackung optimal.Die beiden Parallelblöcke lagen einzeln in dünnem Wachspapier eingewickelt in einer soliden Holzkiste welche mit leichtem (Moos)Gummi ausgeschlagen ist.Die beiden Parallelblöcke waren zudem sehr gut, aber nicht übertrieben, eingefettet."Wenn die jetzt noch maßhaltig sind..." gedacht und ab in die Werkstatt zum nachmessen.Rundum, alle Kanten, alle Flächen mit Mikrometer und Haarlineal überprüft.Alle Flächen plan geschliffen. 25,00 x 50,00 x 75,00 !!!Alle Gewinde sauber und sehr gut gangbar, ohne übermäßiges Spiel.Wenn alles aus China eine solche Qualität hätte, dann können hier aber so einige ihre Läden dicht machen. (Was auch wieder nicht so gut wäre)Also - Tolle Qualität, die den vergleichsweise sehr teuren Teilen von ..... in nichts nachsteht.Absolute Kaufempfehlung.

1-2-3 Blöcke???
1-2-3 Blöcke sind ja bei uns nicht so weit verbreitet - warum nennt man diese Dinger eigentlich so? Nun das ist recht einfach - 1" - 2"- 3" sind die Stärke, die Breite und die Höhe der Dinger. Diese sind 25 x 50 x 75 mm und haben zum Teil auch Gewinde in den Löchern... M10 - Super, solche Schrauben hat man bei uns einfach im Haus.Bei diesen Dingern gefällt mir die Ausführung der Löcher und die "rechtwinkligkeit" sehr gut. Von der Bohrhilfe oder Verleimhelferlein gibt es unzählige Möglichkeiten, der Verwendung und besonders Wichtig: sie schauen einfach echt gut aus ;)
