Glue joint bits are simple and easy to setup and use to create strong butt joints in timber, as well as making it easier to assemble when applying glue and clamping. The tapered profile allows the timber to be clamped even when slightly out of square and significantly increases joint strength by increasing the gluing surface area.
To use a glue joint bit, get sample work pieces of the same thickness and setup the deepest part of the recess (in the centre of the bit) to be as close to the centre of the timber as possible and run one work piece face up and the other face down. If they do not meet perfectly, adjust the height of the cutter by half of the depth of the uneven surface. Once it can be assembled flush then you can run all your work pieces through.
The GJ-250-Q and GJ-410-H is recommended for joint strength as it can cut to any depth, however if you are working with timber that does not have a straight edge, the GJ-430-BH is great as you can run the work piece against the bearing so you can make super-strong joints of any shape fit snugly together. The GJ-430-BH can also be used freehand if one work piece is fixed in place.
