The v-groove bit is very similar to the core cutting bit above but rather than leaving a rounded shape, the v-bit cuts a “V” shaped channel that runs down to a point. Is it because a trim router and a 1/4" bit would just find that too hard, even if I did multiple passes? A rabbet joint is stronger than a typical butt joint—which is simply two straight edges joined together—because a rabbet provides more of a mechanical connection. Cutting the rabbet creates more surface area where the wood can be glued and therefore creates a stronger joint than simply nailing or gluing together two straight edges. For an even stronger rabbet joint, opt for a double rabbet joint where rabbets are cut into both edges of the adjoining workpieces. Rabbet joints vs. dado joints Due to the nature of a bearing and it’s very smooth rotation, this helps to avoid the router bit juddering or jumping around, keeping any cuts dead straight and accurate to the surface you are working on. 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.

If you are fairly keen on carpentry and joinery, the router is one of the best power tools you can have in your tools arsenal as it can be used for a huge variety of jobs from cutting hinge recesses, mitering worktops, trimming and shaping edges to cutting a whole variety of timber joints. Another example of a specialist router bit is the biscuit cutting router bit used to cut biscuit joints in the absence of biscuit jointer. More info can be found on biscuit cutting router bits in our project here.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?

For the router-table method to be both safe and successful, you must use the proper bit. Although a rabbeting bit seems logical, most are not designed for this application. On most rabbeting bits, the carbide cutter extends proud only on the top and has relief angles ground in the carbide to reduce burning. The bottom of the bit is often an afterthought, with the main body sometimes extending below the actual cutter. Some have a shear cut which, although beneficial when cutting from below, impedes the cut if used above since it directs chips to the base of the cut, which is exactly where you don’t want them to be. Also, many rabbeting bits do not have a long enough shank for the cutter to get to the proper height without seriously compromising how much of the bit is in the collet. Use slot-cutting bits V-bits as with most other decorative cutting bits come in a range of different shapes and angles that can be used to form everything from a deep thin channel to a wide shallow one. Easy to disassemble: You can usually separate a rabbet joint by removing screws and pounding with a rubber mallet. Joints made with nails and dowels are usually easy to pry apart.

How to Cut Perfect Rabbets

The edge cutting bit is again commonly used in cabinet and furniture making for cutting and creating decorative edges, sometimes known as beads in cabinet and table tops, chair and table legs and many other different objects and surfaces.

Flush trim bits come in a variety of cutting arm lengths and diameters, but the most common are ½-inch diameter by a 1-inch length with a ¼-inch shank.When it comes to the business end of a router bit, the cutting edges or teeth, most bits these days should be made of at minimum high-speed steel (or HSS for short) but if you can always go with carbide-tipped bits. Due to this if the profiles are cut the same then essentially a rounded off joint will fit into a cove-cut joint. Very similar to a chamfer cutting bit, the rounding over router bit is generally used to round off sharp and acute edges to leave a nice smooth and rounded one.
