Automatic Measurements
The FITFINDER 1/2 Gauge allows you to find the 1/2 thickness of any material up to 3" thick. Create perfectly fitting joints with zero guesswork, set fences and transfer cutting depths instantly—all with no math or measuring.
The FITFINDER was conceived while founder and inventor, Henry Wang, was developing the Dado Stop. While the Dado Stop solved the problem of cutting the width of a dado, setting the dado’s depth for half-laps still proved challenging. Henry realized that the solution was already there—from a Greek mathematician that lived over 2 millenia ago—Pythagoras. He applied this simple principle of geometry to a common woodworking process, and the FITFINDER was born.
No math or measuring required.
The FITFINDER 1/2 Gauge automatically finds the center of your workpiece using simple geometry. Lock the measurement in place and set the cutting depth of your saw blade/router bit, or set fences.
- Match the material's thickness - Place material under P2, then lower P2 so that it rests on top of the material.
- Find the 1/2 point - The bottom of P3 automatically adjusts to exactly 1/2 the thickness of the material.
- Transfer measurement - Lock in the measurement and use the FITFINDER to set cutting depths and fences.

FITFINDER Lock Miter Bit
Consistently well-fitted lock miter joints quickly and easily.
The lock miter joint can’t be beat for making columns, newels, posts and cabinet scribes, but the bit and stock have to be exactly centered together. Only Microjig’s Lock Miter Bit features the Center Finding Platform milled into the bit body at the precise center of the cutting profile. A solid measuring point to set the correct bit height the first time.
Once the height is correct, only the fence needs to be adjusted to perfect the fit. This greatly simplifies the router table setup for perfect joints with minimal test cuts and wasted stock. Now you can confidently add this important joinery to any of your projects.

Got questions?
Does the FitFinder Work with any other Lock Miter Bit?
Our Lock Miter Bit works with our FitFinder because we have a shelf milled into the bit to set the height from.
No other Lock Miter Bit has this feature, so they do not work as well with our FitFinder 1/2 Gauge.

It all started in a garage workshop...
Henry was working on an intricate project and was challenged with cutting thin strips on a table saw. His frustration with traditional methods sparked one of the most innovative woodworking tools to come out in decades.
After countless hours and prototypes, the Grr-ripper was born. Henry has continued to innovate, and Microjig now offers multiple unique product lines all over the world.
