The Gauge/1 depth gauge has worthwhile features not limited to its accuracy and low price. The tool comes with a novel blade lock that works beautifully, and the plastic molding is shaped like an I-beam in section and appears to be unbreakable.

To use the depth gauge, place the frame over the item to be measured, slacken the blade, gently slide it into contact, and then push the lever to lock the blade in place. The gauge is relatively stable as it straddles a router bit or a sawblade for measuring depth of cut, but I found it had to be steadied sometimes. The range of vertical measurement is 3 in., which is more than necessary for any router bit but maybe a little too modest for a sawblade. The footprint between the two legs is 2-5/16 in.

In good light, measurements can be read to the nearest 1/32 in. or millimeter using a magnifier. The reflective blade, however, isn’t ideal a matte finish would be easier to read.

Veritas Micro-Adjust Wheel Marking Gauge

The adjuster runs through the beam from a small knob at the back end right to the cutting wheel, which moves in and out as you turn the knob. This arrangement works well but makes adjustments a two-handed operation, requiring a little more effort.
