The Infinity Tools Dovetail Spline System makes creating beautiful and strong dovetail spline joints fast and accurate. The spline jigs come in two sizes and can be used at the router table or with handheld routers. The unique spline making sled works with almost any table saw to create perfect fitting dovetail splines that lock in place for beautiful gap-free results. See below to choose the package that's right for you.
Our exclusive Tapered Dovetail Spline System is a surefire way to create distinctive-looking boxes in your shop. This system not only creates eye-catching dovetail spline joints, but reinforces the joinery on your projects.
The unique, tapered groove and spline fit together like hand in glove. The anodized, extruded aluminum router jig works with a brass guide bushing to create a tapered dovetail groove in the corners of your box. You can use a handheld router or a router table to rout the grooves.
Our CNC-machined, HDPE table saw sled with replaceable zero-clearance insert automatically creates the proper taper when cutting the dovetail splines to fit the routed grooves in the box. The stop block on the fence ensures repeatable, accurate widths for the splines. The sled works on most right-tilt and left-tilt table saws with ¾”-wide miter slots.

I incorporate dovetail splines in most of the boxes that I build and have bought and build a few jigs and fixtures to aid in cutting the dovetails on the boxes. This Infinity Tapered Dovetail Spline System looked intriguing so I ordered it and boy am I glad that I did. This is the way to go for great looking dovetail splines.

Excellent System
Excellent system. There is a modest learning curve but the result is very impressive - unusual, very attractive, and very strong splines. Be sure to watch the videos and practice before using on a critical project.

Whether used in contemporary, or classic furniture, dovetail joinery is a highlight of quality woodworking.
Infinity Tools offers a large selection of dovetail bits designed with negative shear angle to provide ultra smooth cuts, and they’re available in all sizes and for all needs. But one thing that doesn’t change … is the general shape of the bit. The weakest point of all dovetail router bits is their neck. To get the longest life possible from this type of bit, we recommend pre-plowing the groove before cutting the dovetail slot.
Pre-plowing is the concept of using a straight bit (sized smaller than the diameter of the neck) to first cut a clearance channel. Start by finding the diameter of the neck of the dovetail bit using a caliper.
Then you locate an appropriate straight bit slightly under the diameter of the neck of the dovetail bit. Use that straight bit to set up the plowing cut.
You make a first pass with the straight bit to remove much of the waste. Remember don’t run this straight bit too fast. Let the bit cut.
The dovetail bit is then used to follow through that channel, but the stress on the bit is greatly reduced, leading to better dovetail cuts … and a longer life for your dovetail bits!
Follow this simple tip and you'll get the best performance from your dovetail router bits.
