To get right to the point, the new 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.

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.

As a bonus, the I-Box can even be used to produce classic dentil moldings! 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". And to make sure you get to use all of the jigs' awesome features, we've include a 1-hour instructional DVD that covers everything from basic setup to advanced decorative joinery.

The INCRA I-Box is packed with innovative features:

  • Use it on your table saw or router table to cut great looking box joints with a stacking-type dado blade, dedicated box joint blade set, or straight router bits.
  • Reversible design works on either side of the cutter Exclusive dual-pitch lead screw mechanism for fast micro-adjusting and a broad 1/8" - 3/4" range of pin widths.
  • Exclusive INCRA GlideLOCK miter bar fits standard 3/4" x 3/8" miter slots with a 0.740" - 0.762" adjustment range.
  • Front and rear blade guards; front guard also stabilizes boards vertically and is adjustable for 1/8" to 1" lumber thicknesses for box joints or even thicker for other applications.
  • The wide fence allows clamping lumber securely into position while cutting much better than hand-holding boards, especially when joining small or large lumber (hand screw clamp not included).
  • Reversible & reusable MDF sub fence dramatically reduces or eliminates tea rout.
  • This exclusive package combines the Incra I-Box jig plus our 080-002 Flat Top Saw Blade package.

Reason this customer chose these products

I wasn’t aware that I needed a certain set up to use on your in lay patterns. It made a world of difference.

I purchased the 6' Dadonator Jr expecting it to perform as described in Infinity Cutting Tools catalog. For the most part it performed as expected. Issues with the actual dado width produced by the blade were not what I was expecting, dado width was close to 1/64' oversized. Customer support experience was not a pleasant one. After many back and forth emails to convince Infinity that I was properly installing and using the blade they agreed to returning the blade for diagnosis at their facility.Three aggravating weeks later Infinity agreed that the blade was not within their specifications and offered to return the blade or give a refund. I chose the refund. During this entire process I got the distinct impression that Infinity Cutting Tools was convinced that their product was not the problem but rather it was something I was doing wrong ,in the end Infinity begrudgingly agreed that the fault was the Dado blade and not user error. Will I buy other Infinity Cutting tools in the future? Yes I most likely will. Nothing is perfect, mistakes happen and I try to be a gracious person.

The pin is set by adjusting up against the blade or bit being used.

The beauty here is when used on a right-tilt saw, the adjustment stays the same, while the size of the blade set changes. Simple!
