Router Bit Suggested RPM & Safety Guidelines

Gluing up a curved edge is tricky. Adding a spline to align the two halves makes things much easier, but a curvy spline!? No worries!

Infinity Tools anti-kickback 3-wing slot cutters are designed for optimal performance and results when you’re milling slots.

And they’ll follow any edge at any depth, for a perfect, and beautiful, joint.

Switching cutters and bearings for the best performance is a simple task. Choose either a ½” or ¼” arbor, then select the cutter thickness preferred. Select the correct diameter bearing for your slot depth, and assemble.

Infinity slot cutters are perfect for milling biscuit slots, or for making grooves that require a specific start and stop point. Best of all is having the ability to mill grooves in curved faces.

Go beyond just straight-line table saw cuts and lay grooves into curves, for decorative features or even to accommodate curved loose tenons for ornamental joinery. Infiinity’s slot cutters will open worlds of possibilities for ornamental features or specialty joinery.
