Description

The INCRA I-Box is the most advanced tool ever produced for creating a stunning variety box joints & finger joints. Its revolutionary design allows faster setup, greater versatility, and improved user safety compared to traditional jigs. At the same time, it's easy to use and the included 1-hour instructional DVD covers everything from basic setup to advanced decorative joinery.

The I-Box is an evolutionary leap forward from conventional box joint methods - 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 & provide a whopping 1/8" - 3/4" range of pin widths. It's capable of making good fitting box joints using any width cutter within that range into lumber from 1/4" to 1" thick.

The advantages continue far beyond the basics: I-Box exclusive joints like the Center Keyed Box Joint can be used to produce symmetric patterns on any width lumber, allowing you the flexibility to create joinery that matches existing project plans rather than altering board widths to fit the limited possibilities of traditional box joint jigs. The Splined Box Joint is yet another INCRA-only decorative joint that's guaranteed to add wow-factor to your projects, and the I-Box can even be used to produce an unlimited variety of classic dentil mouldings!

Nothing says "craftsmanship" like adding solid wood hinges to your projects, and 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". Works with the metric HingeCrafter, too.

Made in USA.

WOOD magazine review

Make quick and easy box joints perfectly

Review Summary

Box joints are not complicated to make, whether on a tablesaw or router: It’s a simple matter of step and repeat using a shopmade keyed jig for consistent spacing. But Incra’s I-Box makes the process even easier and safer. And don’t let its complicated appearance intimidate you—it’s incredibly simple to use.
The I-Box’s adjustable metal key lets you set the finger width to any measurement between 1/8" and 3/4", and the microadjuster fine-tunes both the key width and spacing for a perfect fit. The jig rides in your saw’s (or router table’s) miter slot on an adjustable-width miter bar. It has an aluminum slotted fence, workpiece support, backer board, and guard to register and capture your workpiece, holding it securely with no need for clamping while also preventing tear-out. (When you close the jig up against your workpiece, the cutter is fully guarded, keeping your fingers safe.) I made dozens of joints in multiple sizes and never had to make more than one test cut and adjustment each time. And I quickly and easily calibrated it to my router table after starting out on the tablesaw; it works equally well on both. —Tested by Tom Brumback
