Convenient, Practical and Foolproof for Consistent Setup
There are many great, detailed reviews here already for these bars, so I won't waste my time or your time repeating the same stuff. I just wanted to say that I've had these bars for over two years and I find myself using them often. I use them for router height adjustment frequently. It's super easy to straddle the bit with one of these - much easier than with some other specialized devices that are too narrow, where the plate interferes with their stance. I also use them a lot on the table saw. In either case I gently turn the bit or blade until it's barely kissing the bar. This is a time saver to me. I love the case. It keeps them organized, protected and handy. I use the tab end of the bar sometimes, but not as often. When I use it, though, it's really convenient. Is $40 cheap? No, but I don't see how spending hours trying to find a cheaper solution and gluing aluminum foil to bar stock makes any sense for a woodworker. Do you really care that you spent the difference between the bar stock and $40 two years ago? Do you really want to mess with cutting up pieces and gluing aluminum foil? Wouldn't you rather set your blade height and start building something from wood??

Very useful and well made too
Hi, These bars are working very well for me. I added a lift to my router table recently. With the combination of the lift and the setup bars I'm able to get the height and depth configured much more accurately. It has greatly reduced the need for test cuts in scrap wood. They have a good range of sizes that's been adequate for all my needs. You can also use them to setup or verify the settings on your table saw. They are so simple in design but surprisingly helpful. Additionally, he construction is impeccable. The bars are machined from high quality aluminum and the case is also nicely built. It was money well invested. I expect them to last a long, long time. Regards, John

Most versatile gauges
These things are stupidly useful! I dont mind the price anymore, they get used more often than any other gauge i have and they are exactly 1/4 inch thick wo you can stack three and three and use the seventh one to span the gap and you can add 3/4 of an inch to any one of them! So recently i used this technique to lift my bit exactly 1 1/4” by stacking the six smallest and using my half inch over my long router bit, it was the only way i was going to get square 3/4” box joints on my box joint jig since my jig sits a half inch proud, i love these things

If you're measuring, you're doing it wrong
I bought my set of Kreg Precision Router Table Set Up Bars at the same time I upgraded my router table. After using them a few times, I'm starting to appreciate a bit of advice I've seen a couple times on woodworking sites: "Don't measure. Gauge." Although these and other setup bars don't completely capture the essence of that statement, they give you a nice taste of how you can save time get more accurate, repeatable results by measuring *less*. What I like: easy to use - what used to take 2-5 minutes now takes 5-30 seconds case - guarantees that I'll always put them away and take care of them What I don't like: price - they're pretty expensive, at almost $40 for the set of 7 versatility - no metric version; bars only come in sizes ranging from 1/8" to 1/2" in 1/16" increments If you haven't used set up bars before, it'll take a couple of uses before you can break out of the usual workflow. Whereas I used to have to measure, adjust, set/tighten, and repeat; now I can just put down the set up bar, make my adjustments, set/tighten (if necessary) with the bar still in place, then put the bar back in its case. It used to take me several minutes to adjust the bit and fence when I measured with a scale or tape measure, and I ended up with somewhat imprecise results. Before, I dreaded having to change an adjustment if I knew I was going to need the current adjustment again later. But now it only takes me a few seconds, and my adjustments are always dead on and easily reproducible. The bars are very easy to handle, with a lot of gripping areas (my fumbling hands haven't dropped one yet), and they're very easy to use. I got used to setting my router's depth pretty quickly, but it wasn't until after a few more rounds of routing that I had to smack myself upside the head for not using them to set the fence. So far, the depth gauge (the hump on the top of the bar) hasn't been very useful to me except for something to grip when pulling out or putting away a bar. Although you might think it would be nice to have additional sizes from 9/16" up to 1", it isn't necessary, because all the bars are exactly 1/4" thick. That means you can stack them to go even beyond 1". For example, if you want to adjust your router bit's cutting depth to 1-1/4", just stack 3 bars on each side (using 6 bars so far) for 3/4", then put the 1/2" bar across the two stacks. Or if you need to set the router fence to 2" from the edge of the bit, just set the first 6 bars side-by-side (for 1-1/2"), then set the 1/2" bar on its side next to the first 6. Of course, you could also stack the bars much more creatively, but the math is really easy if you work in 1/4" increments plus whatever final increment is needed. The case is one of the best features: it guarantees that I always safely put away each bar immediately after using it, and I can always find the one I need when I need it. If you have another Kreg product with the same size case (such as the Kreg Jig Jr), you'll want to label the two cases since they're otherwise indistinguishable when they're closed. The only things I don't like are the price and the somewhat limited versatility. At nearly $40 for the set, the Precision Router Table Set Up Bars are quite expensive, especially when you consider that they are engineered to deteriorate with use (the logic is that you damage the soft aluminum bars instead of your even more expensive blades and bits). For comparison, you could instead get a bunch of keyway keys, gauge blocks, or a basic set of brass set up bars (all basically the same thing) for a fraction of the cost of Kreg's bars. If you work in metric, you need to cut less than 1/8", or you need finer graduations than 1/16", you're out of luck. I'm surprised there isn't a metric version yet, but perhaps that will come if these sell well enough. Maybe anything smaller than 1/8" would have left the little fence adjustment nub too flimsy. Although I somewhat regret not trying keyway keys or some basic square setup bars first, I highly recommend Kreg's set up bars.

I love these things. Much less frustration in router setup
These are one of those “I don’t know how I got by before I had these” tools. Actually I do know how I got by: I used a square to measure bit height and fence distance. And it was always imprecise. I cut tests on scraps to check my imprecise setup and measured the cuts and adjusted accordingly. That way is annoying, slow and mistake-prone. Now, when I want to cut a 1/2” dado 3/16” from the fence on my router table, I simply take out those two measuring bars and easily and precisely set the bit height and distance. So easy. So correct. Love these bars. Also use them on my table saw, especially for blade height. Only gripe is that it seems to be expensive. I’m not sure why it costs $55+ to make 7 little aluminum bars.

Pecision is as precision does. If you want quality then pay for it.
I love these. I use them to set up my table saw and router. They are especially helpful when setting the table saw up on a bevel. They are awesome for checking your depth of cut (dados, rabbets etc.) They are precision made and made from a softer aluminum as not to damage your bits or saw blades. Take care not to damage them as the are soft. The only thing is i would like to see more sizes and even a metric set. However i do highly recommend these.
