Choosing the Best Surfacing Router Bit – Buying Guide

CNC router bit

The best router for flattening slabs must use the proper surfacing bits to avoid damage to the wood. A good surfacing router bit is vital in getting the job done quickly and efficiently.

Here are some factors to consider when choosing a surfacing router bit:

Project Type:

One of the most important things to consider when choosing a router bit is the project type. For example, if you’re working on a large trim piece, you’ll need a different router bit then working on a minor detail.

The size and shape of the router bit will also dictate the speed you work and the amount of material you can remove in one pass. More significant bits are better for rougher work, while smaller bits are better for more refined work.


When choosing a router bit for planing, it’s essential to consider the shape of the bit. The most common conditions are straight bits and solid carbide spiral bits.

Straight bits are suitable for general-purpose use, while solid carbide spiral bits are better for more intricate work. However, there are also other shapes to choose from, such as carbide-tipped bits and diamond-tipped bits.

Each type of bit has its advantages and disadvantages, so it’s important to select the right one for the job at hand.


One size does not necessarily fit all. The size of the router bit is an essential factor to consider when choosing a bit for your project. The larger the bit, the more material it can remove, making it ideal for shaping and sizing large pieces of wood.

However, large bits can also be more challenging to control, so they are not always the best choice for delicate work. On the other hand, smaller bits offer greater control and precision, making them ideal for detailed work.

In general, it is best to choose a router bit sized appropriately for the job at hand. You’ll soon find the perfect bit for any project with a little trial and error.

Router bits come in all shapes and sizes, each designed for a specific task. But with so many options to choose from, how do you know which router bit is right for the job? The answer lies in compatibility. When choosing a router bit, it’s essential to consider the compatibility of the bit with your router.

Certain bits are only compatible with certain types of routers, so it’s crucial to ensure that the bit you choose will work with your router. In addition, some bits are only compatible with certain types of materials.

So if you’re looking to plane a piece of wood, make sure to choose a router bit specifically designed for use with wood. By taking compatibility into account, you can be sure to select the right router bit for the job.


The material is also essential. Router bits are made from different materials, including high-speed steel, tungsten carbide, and Carbide-tipped. Each type has its own advantages and disadvantages. High-speed steel is the most common type of router bit. It’s affordable and easy to find.

However, it doesn’t last as long as the other types of bits. Tungsten carbide is a more expensive option, but it’s also more durable. It can handle tougher projects and last longer.

Carbide-tipped bits are the most expensive, but they’re also durable. They’re ideal for professional woodworkers who have needed a high-quality bit for years.

Cutting Diameter:

When choosing a router bit, the cutting diameter is probably the last thing on your mind if you’re like most people. After all, what’re a few millimeters here or there?

But believe it or not, the cutting diameter can significantly impact your work. For example, a bit with a large diameter will remove more material with each pass, saving you time when planning large surfaces.

On the other hand, a bit with a small diameter can offer greater precision, essential for intricate work. So next time you’re shopping for bits, don’t overlook the cutting diameter; it might be the deciding factor.

Shank Diameter:

When choosing the best router bit for planing, it is also essential to consider the shank diameter of the router bit. The shank diameter is the diameter of the part of the router bit that fits into the router.

The larger the shank diameter, the more material can be removed with each router pass. However, larger shank diameters also require more power from the router and can cause more vibration.

Cutting Wings:

The cutting wings are the portions of the router bit that contact the material being cut. They are typically made from high-speed steel or carbide, and they are available in various sizes and shapes.

The size and shape of the cutting wings will significantly impact the quality of the finished surface. Therefore, it is crucial to select a router bit with the appropriate cutting wings for the job at hand.


Last but not least, the most crucial consideration is the construction of the router bit. The design of the best router bit will have a direct impact on the performance and longevity of this versatile woodworking tool.

For example, a cleaning router bit with a spiral flute design will offer superior cutting performance and a longer lifespan than a straight flute bit. Similarly, a carbide-tipped router bit will stay sharp longer than a steel-tipped bit.

With so many factors to consider, it’s essential to consult with an expert before making your final decision. By choosing the right cleaning router bit, you can ensure that your project turns out just the way you envisioned it.

Types of Router Bits Every DIYer Should Know

There are many different types of bits available on the market, each designed for a specific purpose. If you’re new to woodworking or just looking to expand your collection of bits, here are some of the most popular types that every DIYer should know:

Straight Flute Router Bits:

Spiral Flute Router Bits:

Spiral flute router bits offer superior cutting performance and are ideal for use on hardwoods and other materials that are difficult to cut with a straight flute bit. Spiral flute bits are available in a wide range of sizes and shapes, so you can find one perfect for your project.

Flush-Trim Router Bits:

Flush trim router bits are one of the most essential and versatile woodworking tools in a woodworker’s toolkit. By definition, a flush-trim bit is used to cleanly trim the edge of one workpiece to flush with another.

This can be an advantageous technique when joining two pieces of wood together or creating a uniform edge on a workpiece. The flush trim bit is the most commonly used of many types of router bits.

Chamfer Router Bits:

Chamfer bits come in various sizes, each with a different depth and angle. The most popular size is the 45-degree chamfer bit, but you can also find bits with other angles, such as 30 or 60 degrees.

Chamfer bits can also be used for rabbeting and beveling edges. Be sure the shank size of your chamfer bit matches your router. The maximum speed rating should also be considered. Choose a bit that can handle speeds.

Molding Router Bits:

Molding router bits are a specific type of bit designed to create decorative moldings. There are many different styles of molding bits available, each of which produces unique results.

Molding router bits can be used to create simple or complex designs, depending on the user’s skill. It is possible to produce professional-looking results without any special training with a little practice.

Rabbeting Router Bits:

If you’re looking for a router bit that can do a little bit of everything, then you want a rabbeting bit. Also known as a rebate bit, a rabbeting bit is designed to cut a groove or notch into the edge of a piece of wood.

This is perfect for creating Tongue and Groove joints or making Dados and Grooves. But that’s not all a rabbeting bit can do. With the right setup, you can also use it for Flush Trimming and Edge Profiling and Shaping.

Stile and Rail Bits:

If you’ve ever looked at a piece of wood furniture and wondered how they got those clean, straight lines on the edges, you’re in for a treat.

Stile and rail bits are essentially significant router bits designed to cut through thick pieces of wood. Most stile and rail bits have two cutting surfaces, one for the stile, or vertical piece, and one for the rail, or horizontal component.

The cutting surfaces are usually ground at different angles, which helps create various edge profiles. You can create a traditional ogee edge profile or a more modern square edge profile using a stile and rail bit.

Joinery Bits:

As any woodworker knows, joinery bits are essential for any woodshop. These specialized bits allow you to create precise, tight-fitting joints essential for strong and durable furniture.
