Glue Joint Bits

Why don’t we just simply glue two flat pieces of wood together? The V-form gluing profiles cut by these router bits enlarge the glueing surface, and make for a stronger joint. This method is often questioned today, as modern glues are so strong and reliable that the grooves are thought to be unnecessary. But the decision depends also on the judgement of the woodworker in terms of the use and potential stress on the piece. But in one important sense, using these kind of joints is always an advantage - the individual board cannot slip or bow during glue-up -- the groves keep them alligned to a very close tolerance.

These Sistemi Klein router bits are Tungsten Carbide tipped (TCT). Because of their size, these glue joint bits should only be used in a router mounted on a router table.

This router bit consists of 5 cutting disks 1.85 mm thick, 1 cutting disk 5.5 mm thick and spacers. When all the cutting disks are mounted on the bit shaft, the bit is capable of profiling workpieces of between 31 and 38 mm thick. But you can leave off or remove the individual disks so as to be able to cut glue joints in thinner boards, as well. See below. Click on the photo below to see an enlarged photo.

The bit comes assembled as seen in the photo. The package also includes:
2 ring bearing spacers 16 x 3.4 mm, for shaft diameter Ø 8 mm
10 ring bearing spacers 16 x 0.1 mm, for shaft diameter Ø 8 mm
5 ring bearing spacers 16 x 0.05 mm, for shaft diameter Ø 8 mm
With the optional ring bearing spacers, the spacing of the cutting disks can be still further adjusted.
