Taytools 469744 1-2-3 Blocks No Holes Matched Pair (2 Each), Hardened Steel RC 55-62, (1"x2"x3") 123 Precision Ground Machinist Set Up Blocks

Great heavy and flat blocks

You know it's gonna be accurate and reliable!

Needed some solid, no hole blocks to calibrate a laser table. Have some Wen 1–2-3 blocks that are exact, but the holes interfered with calibration. These blocks are as exact as the Wen blocks (perfect!) and worked exactly as needed. Edge chamfering took care of any edge burr issues that I could see, which were none. Would recommend to anyone needing solid 1-2-3 blocks.

I assumed that TayTools was a small, American manufacturing company (only my impression from the influencer that recommend them) but these are from China, as most things are these days. I wish Amazon would clearly state the counter of origin on their items.

Delivery was quick and arrived in an unmark box. The acuracy and quality of the 3,2,1 block are great and measured dead on. I also use this variety of aplications like checking the square on my table saw fence and thanks to this blocks i was able to square my fence to the blade. Great tool to have.

I bought another pair of blocks from another manufacturer at the same time and while both sets measure accurately, this set is nicely machined. No need to look any further. These do what they are supposed to do, are accurate, and about as well machined as anyone could expect at this price. That is not a cut on the product, i think if i wanted better machining i would expect to pay something in the area of 10x this price, so even at double the price i would have been very happy.

I can grind these blocks parallel and square closer than they come. If they go undersize it doesn’t matter. You can’t buy the steel rough it in, heat treat it and grind them to size for the price.

After reading about several setup blocks covered in anti-rust goop, I thought I'd get solid ones since I have no plans on using the threaded holes. When these arrived I was surprised how heavy they were. It's not a problem, but I'm using these to set bit and blade heights so it would be nice if they moved around a little more easily so I could worry less about hitting my carbide cutters with one. Again, no complaints with these, I'd just get blocks with holes drilled through them so they'd be lighter. Incidentally, these were not covered with goop.
