Glue joint bits assist joining two pieces of material by creating identical, adjoining tongues on the edge of both pieces. The notched cuts create plenty of surface area for gluing and form a tight-fitting joint that holds the pieces together while they’re being clamped. They’re available in two varieties: standard and mitered. The standard glue joint joins squared edges, while the mitered bit is made with a 45-degree angle to join two mitered edges. However their main purpose is for creating decorative edges commonly used on tables, doors of various types, shelves and the similar.

A rabbet is like a dado that’s missing a side. It’s essentially a notch cut into the edge of a board or piece of plywood.Rabbet cutting router bit and rabbet or shoulder joint cut – Image courtesy of mullerconstructionsupply.com Edge Cutting Router Bits

Or I could use my new table saw to cut twice and get a rabbet like that... but I was wondering why I'm finding it difficult to source this - usually there's a reason, right? As with all other bits that produce accurate cuts, the rounding bit also includes a bearing guide at the base that is also used to control the depth of cut. Due to this rounding bits also normally include a range of different sized bearings that can be swapped out depending on the depth of cut required. Attractive: You can place the seam where it isn’t visible — say, under a countertop — and the fasteners can be hidden with filler or made from doweling. The above bits are fairly common in terms of use, most joinery workshops will have them, but there are some router bits that are only used for specific jobs, these are normally referred to as specialist bits. In this episode of Getting Started in Woodworking, the forth in our series on building an oak bookcase, we demonstrate how to cut accurate dadoes and rabbets with a router and a simple jig.The majority of router bits that feature a bearing normally also include bearings of different sizes with the bit or in the kit. As the bearing follows the object your are working on, the size of bearing dictates the depth of the cut, so for a different depth of cut you can simply change the bearing for a different size. The straight cutting router bit is arguably the most commonly used type of router bit. As the name suggests it’s used for cutting straight cuts with a flat base e.g. the channels at the side of drawers that the drawer bottom sits in and certain timber joints such as a lapped joint.
