Router Table Box Joint Jig machines 1/4" 3/8" and 1/2"

Description

Box joints are strong and attractive, and with the help of our Router Table Box Joint Jig, they're also straightforward to make. This jig uses precision-machined solid brass indexing keys to ensure uniform finger spacing and an airtight fit. Keys are included for three finger widths: 1/4'', 3/8'' and 1/2'', and can be used with stock up to 3/4'' thick. The smooth-sliding sled features long ''skis'' that keep it square to the bit and tabs on the bottom that stop the sled at the end of the cut. Lock it into the miter slot of your table with our comfortable Easy-to-Grip knobs and you're ready to rout.
Features:
Solid brass indexing keys ensure uniform spacing and tight finger joints
Indexing keys store neatly in slots behind the sled
Comfortable ergonomic knobs lock platform into 3/4'' miter slot
Sled is made of durable glass-filled nylon, slides smoothly and provides ample support
Sacrificial MDF fence face helps control tearout
Dimensionally stable MDF platform has low-friction melamine coating for easy sliding and durability
Notice: Requires a straight router bit (sold separately) to match the size of the indexing key. Up-cut spiral bits deliver the cleanest cuts and help prevent blowout.
