With the correct bits, you can make decorative edges, trim veneers and laminates. You can also rout hinge mortises. Furthermore, you can cut woodworking joints like dovetail, dado, mortise-and-tenon, rabbet, tongue-and-groove, etc.

Types of Router Bits

The market is awash with various router bits of varying styles and sizes. So, if you’re a newbie in using a router, you might get confused when buying router bits You should familiarize yourself with the following types of router bits:

1) Straight Router Bit

The straight router bit is the most commonly used router bit type by woodworkers. You can use this router bit in various applications, specifically for cutting different square-shaped grooves. Moreover, you can cut these grooves along the wood grain, against the wood grain, or along the wood edge. 

It gets called a groove if you cut along the wood grain, while it gets referred to as dado if you cut against the wood grain. These different cuts come in handy when you join two material pieces. 

For example, using the straight router bit, you can make mortise and tenon joints. This jointing technique allows for sturdy joinery. 

You can also use the straight router bit to mortise your door hardware. Besides, you can use it for making grooves for a channel to allow for the insertion of decorative inlay. Moreover, you can use the straight router bit for rabbeting. 

The diameter range of straight router bits is from 3/16″ to 1-1/2.” They may also come with one flute or two flutes. The straight router bits are best for making dados, grooves, decorative inlays, and mortises.

2) V-Groove Router Bit

The V-groove bits can hollow out a V-shaped profile in your wood piece. This V-shaped profile is often meant for aesthetic effect. This router bit can engrave various designs on any flat surface, such as on the face of the cabinet. 

You can also make shallow grooves that span the column’s length. Besides, you can use this bit to make panel ridges creating a beadboard effect. 

The V-groove bits also come in varying angles and diameters. Again, you will find flat-bottomed bits instead of having sharp tips. Such V-groove bits allow for a limited cut depth. The V-groove bits are perfect for making fluted columns, signs, and bear-board designs on panels.

3) Flush Trimming Router Bits

The flush trimming router bits are made for cutting unclean edges and overhanging edges to make them flush with the adjacent surfaces. You can use these bits when working on wood veneer and laminate coverings because often, the use of these two engineered wood leaves overhanging edges that you must trim back. 

You need to use these bits with guides to ensure that the cutting bit produces surfaces flush with the adjacent surfaces. Besides, using a guide implies that the bit should have a bearing at the bottom or top.

4) Chamfer Cutting Router Bits

The chamfer cutting bit gets also referred to as the bevel cutting bit. You can use this router bit to shape the material’s edges, especially when you are building worktops, shelves, and other projects with sharp right-angled edges that you must remove. 

You can cut a 45-degree bevel edge using this bit. As such, it is also rightly called a bevel router bit. You will find this router bit in various cutting angles to let you create varying shaped objects. This router bit also comes with a pilot bearing guide fixed to its base.

Besides, the distance between the cutting teeth and the ball-bearing pilot determines the slot depth. 

The most commonly used slot cutting bit is the 1/4″ wide and the 1/2″ deep. You can alter the depth of cuts by choosing a different cutting bit diameter.

12) Rounding-over Bit

Another type of router bit is the rounding-over bit. You can use this bit to shape the edges of tabletops, shelves, chair arms, and other sharp edges that you would like to soften. This bit features a ball-bearing pilot that allows you to control the cut’s width. 

You can also adjust the router’s cutting depth by adjusting the router base. The rounding-over bits come in different sizes. Nevertheless, the most commonly used rounding-over router bit sizes are the 3/8″ and the 1/4″.
