iGagingSnap Check Height Gauge for Woodworking Jointer/Router/Planar Blade

Great tool for checking the height of a table saw blade or a router bit. Easy to use.

This is my second one. Had my first one on top of my beisemier table saw fence and accidentally knocked it off with the saw running. I now hang my new one on the wall. A must have for setting router bits on the table router when making doors

It does what it is supposed to do and does a decent job for the price. I seem to have to zero it out every single time I place it down even when placing it in the exact same spot immediately after using the gauge, which makes me question it's accuracy somewhat. It seems to be plenty accurate enough for woodworking, but I would not trust this device if I was a machinist. The plastic feels a bit flimsy and I wish it was heavier as it will only sit flat if you hold it or the surface is magnetic. Great for a cast iron table saw, not great for a milled aluminum router plate or job site table saw.I wish there were a similar item with higher quality. I'd happily pay $30 if the body were made of metal.

This is the greatest thing for setting router and saw depth/height with reasonable accuracy. It's not perfect (see below) but it's still hugely more accurate than setting with a machinists ruler and It is so inexpensive that there is no reason not to use one. It reads out in metric/inch decimal or inch fraction. One thing to note is that the body is plastic, so it has some flex to it depending on how you hold it to the work surface. If I hold it by the upper finger grip part of the handle I get quite a bit of flex, about +/- 5 thousandths. I've had the best luck just using two fingers pressing down on the lower part of the handle, this cuts the flex down to about +/- 1 thousandth. In truth, for woodworking depth of cut adjustments, either is fine, a few thousandths just isn't an issue. If I were using this for metal working, it might not be acceptable. The bottom line is that for the price, this thing is awesome.

I use these for checking the alignment of the pressure vessel heads to the shells. The gap between the body and the measuring head allows the gage to go over the weld reinforcements allowing for an accurate measurement directly from the shell to the head. There is no better gage out there to make this measurement. I wouldn’t be without one in my toolbox!

I bought this to aid in installing jointer blades, and thought it would be useful in other areas as well. The first thing I noticed is that the only thing magnetic is the base. This will not hold blades in the correct positition. The gauge arm will not lock in any postition, but is spring loaded. One can reverse the readout, but my "thumb screw" required pliers to both loosen and retighten. I found the zero feature to be very finicky. I usually have to zero 4 or 5 times before I actually get a "0" reading.I did try to set the jointer blades with this gauge, but it made a tricky process even trickier. After zeroing and measuring height of the blade on one side of the bed, you'd have to rezero when moving to another postition on the bed. This really isn't acceptable and I would not recommend this tool for setting jointer blades.The unit seems like a good idea. Mine came with two extra batteries - nice. The plastic seems sturdy enough for its intended purpose. Maybe it'll be better suited for setting table saw or router height?

I'll start off by saying if you need accuracy that your life depends on, this product probably isn't for you. However, if within one or thousandths of an inch is fine, then go for it! It was ready to go right out of the box and came with a spare battery and screw. The magnets worked fantastic on my jointer table and it was very stable yet easy to move around while I was adjusting the blades. If I move the product drastically / quickly it seems to go out of zero by 1 or 2 thousandths (I'm banking off the fact my cast iron jointer table is perfectly flat) so I would rezero it between measurements frequently but it really wasn't that big of a deal - super easy to do. Jointer cuts perfectly after setting the blades with this - very pleased with it.

THIS IS A GREAT GAUGE FOR THE JOINTER. I USED THIS IMMEDIATELY THE DAY I GOT IT. RE-TUNED MY JOINTER. GLAD I GOT THIS IN-EXPENSIVE MUCH NEEDED TOOL. WISH I HAD THIS YEARS AGO.THE MAGNETS HOLD IT PERFECTLY ON THE TABLE. I EVEN GOT 2 EXTRA BATTERIES FOR THE MEASUREMENT DISPLAY. THIS WAS A SMART PURCHASE!!
