What it is for
Centres dowel holes consistently in the edge and face of a board. Cheap, strong and invisible when done well. This guide covers what the tool does, the specification points that actually change your results, and how to use it without damaging the work or yourself.
Where it fits in the build
This is a join stage tool in the Joining & Fastening category. Hold parts together with joints, jigs and screws.
Using it well
- Use dowel centres to transfer the hole position from one part to its mate.
- Cut a shallow groove in the dowel — trapped glue has nowhere to go and can split the workpiece.
- Keep the jig clamped tight; any movement shows up as a misaligned joint.
Compatible materials
Materials this tool handles without compromise. Where a material is not listed, check that the tool is rated for it before committing to a cut.

Reference sample in 3D
The model above is a real ash reference block rendered in the browser. It is simulated from a height field rather than photographed, so you can rotate it to see how light behaves across the grain, the end grain and the edges. Drag it, or use the view buttons to look at the top face or the end grain in isolation.
Reading how light falls across a board is the fastest way to judge whether a surface is flat. That is the same judgement you make with a hand plane or a sander, and it is much easier to see on a rotating model than on a static photo.
