If you have experience in woodcraft, you’ll know that many projects require smooth textures. These textures are often created by shaving the wood off a rectangular or square piece. To achieve this, you’ll need the help of a router bit.
The best router bit will ensure your work is fast, efficient, and foolproof. It should hollow out your wood to your desired shape without bruising the workpiece. This means that the router bit should be razor sharp but also incredibly reliable and fast.

Understanding the Router
The first thing that you should know is how the router works. This is important because there’s no use knowing all the facets of a router bit without understanding the primary equipment.
For starters, routers are power tools that are operated by electricity, much like all of the power tools today. However, dating back in the early 1900s, these tools did not exist. On the flip side, there were manual routers back then that made wood hollowing possible. Thanks to this, an architecture developed the concept of wooden staircases without the existence of the power router.
Nowadays, the non-powered router has faded, being replaced by motorized routers. These routers work similarly to grinders since it shaves off portions of wood by using friction and rotations per minute (rpm).
Jet Motor Hand Routers invented the first handheld router in 1915. It was one of those great inventions that resulted from an accident. This is because the founders of the router intended it to be used as an energy source for a locomotive’s headlights.
The inventors initially invented an air turbine, which was denied by the railroad company that requested the project. A few months after its rejection, it was reinvented as a tool to smooth out grooves in chairs. This idea popped out after the inventor realized how impractical and hard it was back then to use a router plane.
What You Need to Know About Router Bits
Although the base and body of the router are necessary, a router is worthless without the bit. The bit, like the pieces of a hand drill, is what hollows the wood. These are extremely important because it dictates the outcome of your desired groove or angle.
In today’s time, router bits have been modified a hundred times to suit different joinery needs and decorative demands. Router bits can be classified as a high-speed steel bit or a carbide-tipped bit. These two are heavy duty compounds that companies use to construct router bits.
Edge bit and non-edge bit
Moreover, router bits can also be divided into two categories regarding its purpose. These two are the side pieces and the non-edge its. There’s a lot of technicalities involved in it, but simply put, this is the hollowing performance of the bit.
The edge bits have a small bearing which can be adjusted to meet different depth requirements. This enables the craftsmen to shift the diameter of the bit for rabbeting bits freely.
On the other hand, the non-edge router bit is primarily used as an anti-kickback bit. This means that if the craftsmen want to play safe, this is the bit of choice. Non-edge bits are secured router bits that prevent any “kickback” which is a carpentry term for unwanted hollowing.
When buying a router bit, take into consideration the size as well. Most router bits come with an interchangeable size that shifts between ½ inch and ¼ inch. Between the two, the ½ inch shank offers more stability and precision. It’s more ideal to use on a regular basis.
Types of Bits and Wood profiles
There are many variations of bits as we previously mentioned, knowing the main types is essential for you to get a clearer idea of the bits that you’re going to buy. Below are some of the types to know:
- Straight bit - This is the most common and arguably the most used among all wood projects. It’s a straight-line bit that hollows the wood against the grain, creating a “dado” profile on the wood. The dado pattern looks like two parallel towers, with a defined and hollowed space in between.
- Rabbeting bit - This bit is what we mentioned earlier. It makes use of a bearing at the tip which increases the cutting diameter. This is typically used for joineries since it creates a stair-like pattern on the wood. The rabbeting bearings can be purchased in a set, giving you a lot of versatility.
- Chamfer bit - One of the wood profiles that is aesthetically pleasing to see. These are rounded squares or rectangles that are done to polish up a surface. You’ll often see these on a table top. The bit’s specialized bevel is what causes this smooth edge.
- Cove bit - Another aesthetic profile, the cove bit causes the side of the wood to form a concave slope. This is usually applied to high-end furniture, most notably a Victorian-inspired dresser. It’s also a common pattern used for wooden pillars.
- Dovetail bit - Dovetails have their power tool that’s specifically designed for creating a dovetail joint.
- Edge forming bit - Edge forming bits are complex decorative designs that are used for aesthetic purposes. Quarter rounds that are used to improve your wall and flooring and ceiling design are the application of this wood profile.
Tips when searching for quality router bits
One great tip to remember is that the wood’s surface after hollowing will tell a lot about the bit. Although any bit might get your desired wood profile, get a magnifying glass and look for the nitty-gritty details on the wood.
When speaking of details, everything rests on the abrasion that the wood receives. Check for any unnecessary wood shavings and uneven edges. These are usually the features that artisans tend to overlook. A good router bit should both hollow and smooth out a workpiece. Hence, the grain of the wood should be still similar before using the router.
Our Top 5 Picks
Freud comes with a ¼” top bearing shank. However, it comes in 17 more styles and sizes to fit your needs. It boasts of its TiCo hi-density carbide cuts which can ensure you of its durability.
It can cut through all composition materials such as plywood, hardwood, and softwood. But it can also be used for template work, lettering, grooving and routing out work pieces. This is because of its top mounted bearings. Also, it can also be utilized for either handheld or table mounted routers.
