To get right to the point, the INCRA I-Box is the most advanced tool ever produced for creating a stunning variety box joints & finger joints. It features fast setup for basic joints, plus advanced capability for unique decorative joints. Its revolutionary design allows greater versatility and improved user safety compared to traditional jigs. This single jig can be used on both your table saw and your router table, and the I-Box's dual-pitch lead screw mechanics easily micro-adjust joint tightness and provide a whopping 1/8" - 3/4" range of pin widths in lumber up to 1" thick.

The advantages continue beyond the basics: INCRA I-Box-exclusive box joints like the Center Keyed Box Joint can be used to produce symmetric patterns on a wider variety of lumber widths than traditional jigs, making it easier to adapt box joints to existing project plans. Taking the Center Keyed joint a step further, the Splined Box Joint is yet another INCRA-only decorative joint that's guaranteed to add wow-factor to your projects.

Altering the spacing between cuts and height of the cutter lets you change the moulding's proportions to create a nearly infinite variety. And Nothing says "Craftsmanship" like adding solid wood hinges to your projects. The I-Box can be used in conjunction with the INCRA HingeCrafter to produce wooden hinges in four different barrel diameters and in lengths up to 10".

Lily ★★★★★

The micro-adjustment knobs let me dial in perfect finger joints in seconds, and the included flat-top blade left zero chip-out on my test cuts. I’ve never had such clean results on a box joint jig before.

John V. ★★★★★

I was cutting right away with zero tear-out because the flat top blade leaves such a clean edge on every finger joint. The jig itself locks into place with a satisfying click, making each pass repeatable without needing to measure again.

Olivia ★★★★★

The setup took me about ten minutes, but once the jig was dialed in, cutting a full set of finger joints on the table saw was almost embarrassingly easy. The flat-top blade gives those crisp, clean shoulders that make the joints look like they came from a factory.
