Box joints (also called finger joints) are strong, attractive joinery for boxes, drawers, and cabinets. A dedicated **box joint jig** on your table saw lets you cut evenly spaced “fingers” with consistent depth and spacing — much more accurately and safely than trying them freehand or with a miter gauge alone.

How Box Joint Jigs Work
Most box joint jigs use an indexing fence that holds your workpiece and lets you make evenly spaced passes through the table saw blade. You set up the first cut, then index the jig forward by a fixed amount for each subsequent cut, creating evenly spaced fingers. When both sides of your box are cut and assembled, the fingers interlock and create a strong joint that’s ideal for boxes and cases.
Features to Consider
- Adjustable Spacing: Lets you cut different finger widths for various box sizes.
- Fence Stability: A stable fence prevents chatter and leads to cleaner cuts.
- Ease of Setup: Some jigs require more fine‑tuning — choose one that matches your comfort level.
- Compatibility: Make sure the jig fits your table saw’s miter slots and blade height capabilities.
Tips for Using a Box Joint Jig
- Test on Scrap First: Always verify spacing and fit with scrap wood before cutting your final pieces.
- Use Featherboards: Add featherboards or hold‑downs to keep stock tight against the fence.
- Match Blade Width: Many box jigs work best with a dedicated box joint blade set for cleaner pins and tails.
- Check Fit Often: Minor adjustments after initial progress keep joints snug without forcing them.
