Buying guide
How to choose a joinery jig
The right jig turns joinery from guesswork into a repeatable setup. Machined aluminum bodies hold their reference faces, so every hole lands at the same depth and angle.
Match the jig to the joint: pocket holes for fast cabinets and face frames, dowels for hidden alignment, mortise and dovetail jigs for furniture that shows its craft.
Pocket or dowel?
Pocket holes are faster and need fewer clamps; dowels hide completely and align panels.
Set the stop collar
Bit depth is what makes a pocket joint hold. Set it once per stock thickness.
Clamp across the joint
A face clamp keeps boards flush while screws pull the joint closed.
Common questions
What stock thickness do the jigs handle?
Most cover 1/2 in. to 1-1/2 in.; check each listing.
Are the jigs aluminum?
Yes, bodies are CNC-machined, anodized aluminum.
