Fast and precise lock miter joints
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.

Use it around your whole shop.

What people are saying.
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.
