High Precision Aluminum Dovetail Jig Metric and Imperial Tenon Caliper Card Gauge for Measuring Height Woodworking Saw Table Machine Gaps Precision Measuring Tool,MG-016B

Very easy to find the router bits sizes, METRICS or SAE and set the depthnes needed for your projects, strong, durable and defined, I like it 👍

Nice size and easy setup tool to measure blade and other things with

For a sub $10 item, this tool is handy to keep by your router table or table saw.The blade height gauge is accurate for both metric and imperial gauges according to my calipers. The numbers can be hard to read, but given the number of heights in the gauge, I am not sure you could do much better.The "dado" sections are accurate-ish (there is variation of a few thousands of a mm/inch and its not consistent across the who gauge) when I check them. I am not really sure how useful this part of the tool is, but if you needed to check the width of a dado quickly, it will do the job.Overall this is a handy tool for a sub $10 price. I keep it in my shop apron.

Very accurate and worth the money if you use power tools a lot.

This product looks great but needs to be shipped with instructions on how to use it.

The price for this item was just right. Though I haven't used it yet, I can tell it will be very helpful in my shop.

I'm ordering a few more of these for my shop to keep at my drill press and 2 router stations so I won't have to keep moving the one I have away from my table saw. I have used nearly all the different types of setup blocks, jigs, and tools but for whatever reason this one has quickly become my favorite.

Good price, seems precise so far. Would purchase again. Serves a lot of purposes on my router/ table
