Infinity Tools Shape-Up Finger Joint Shaper Cutter, 3/4" Bore

It works with stock ranging from 1/2" to 1-1/2" thick.

You use the same profile to cut both sides of the joint, so the fingers are mirror images of each other and interlock perfectly. Explore more in the Shape-Up shaper cutters collection.

It has a 3/4" bore and a 1/2" finger joint profile.

The cutter measures 2-11/16" in diameter with a 1-1/2" cutter height.

The optional rub collar helps you set your depth of cut against the fence and centers the joint on the edge of your stock while supporting the workpiece above the cutters. See related shaper cutters & accessories.

They are usually meant for end-grain applications, but you can mix and match different wood species to create dramatic decorative effects as well.

Hold a straight edge across the bearing so it just touches the fence faces, then lock everything down. This aligns your depth of cut for repeatable results.

Finger joints are useful for joining boards end to end and for decorative joinery where you want strong, interlocking connections, including mixed-species work for visual contrast.

Like Infinity's Shape-Up cutters, it uses carbide cutting edges that can be resharpened. Browse sharpening supplies to maintain your tooling.

For high-volume joinery, the replaceable-knife Insert Pro shaper cutters let you change inserts instead of resharpening the head.
