Box Joint Jig for Table Saws

Cut precise, tight-fitting box joints in a fraction of the time it takes to set up a traditional jig. This system pairs custom 3D-printed templates with a flexible finger-and-slot design, so you can dial in exact joint spacing for any project without buying a new jig for every size.

Key Features

Custom 3D-printed templates — precision-fit templates ensure consistent, repeatable finger spacing every time.

Individual adjustable fingers — build your own template on the fly for one-off or non-standard joint spacing, no extra parts needed.

Toggle clamp compatible — mounting points support standard workshop toggle clamps for fast, secure workpiece hold-down.

CNC and non-CNC plans included — build it with a CNC router or hand tools; full plans for both methods are included.

Replaceable insert — the zero-clearance insert swaps out easily when worn, keeping cuts clean and splinter-free.

Snap-lock blade cover — quick-release blade guard snaps on and off for safe, tool-free access.

50+ predesigned templates — ready-to-use templates cover the most common joint sizes and spacings out of the box.

Metric and imperial — fully dimensioned for both measurement systems.

Fits standard blades and dado stacks — works with regular table saw blades or dado stacks for single-pass or multi-pass cutting.
