Different Types of Router Bits

Different Types of Router Bits

Router bits are among the most versatile tool you can buy. They are compatible with routers and drills alike, offering satisfying woodwork. There are several types of router bits. Here are some of the most common types of router bits that everyone should own.

Straight Cutting Bit

As the name suggests, these bits are designed to cut straight and square-based grooves. The bits are available in a range of sizes from ¼ inches to ¾ inches in diameter. These are particularly helpful in cutting rabbets, grooves, and dadoes.

Round-Over Bit

Round-Over bits are used for shaping edges of shelves, chair arms, and more. They are also used in sign-making. You can adjust the base to control the cutting depth. These bits come in a wider range of sizes, from ¼ inches to ⅜ inches.

Cove Bit

So, you’ve been introduced to round-over bits. The cove bits are just the opposite of round-over bits. They will produce a concave radius around the edges of wooden surfaces.

These decorative edges are commonly seen on modern furniture legs, bookshelves, cabinet surfaces, and more. Cove bits can come in a range of diameters, from 1 inch to 1/8 inch. I recommend you get the standard sizes of ¼ inch diameter or ⅜ inches.

V-Groove Bit

The V-groove bits are one of the best router bits for wood carving. They are widely used for decorating drawer surfaces, cabinet doors, and other wooden surfaces. The most popular size in this bit is ½ inch in diameter with a cutting angle of 90 degrees.

45-Degree Chamfer Bit

This is an edge-shaping bit that is designed to smoothen the edges of boards and panels. This tool is commonly used to remove sharp corners and squares from wooden surfaces, picture frames, vertical posts, and such. It is also used to produce V-shaped grooves.

Besides 45 degrees, the chamfer bits come in several other angles and sizes. However, the most common sizes are 1 to ¼ inches diameter.

Slot-Cutting Bits

This is a speciality bit designed to provide accurate and narrow slots and grooves around the edges of door frames, picture frames, and such surfaces. The bit can be detected easily by its wings. There are two wings, and each comes with a sharp carbide tooth. These teeth determine the thickness of the slots you’re going to curve.

Moreover, the bits are equipped with interchangeable pilots so you can switch between different sizes and angles, bringing variation in the design.

How To Pick A Perfect Router Bits for Sign Making?

Even after having the suggestions, finding the right one seems tough sometimes. My buying guide will help you make the right decision.

Look What You Need

The first thing you need to consider is your needs. Ask yourself why you need the bits and what your project is all about. Are you planning to purchase bits for sign-making only? Or do you want to do some other stuff such as carving or drilling as well?

Not all bits are compatible to do all these at once. Make sure you know your purpose and pick one accordingly. Consider the types of materials you are going to work with. Most bits are suitable for wood use only. You want something stronger for metal surfaces.

Is The Bit Compatible with Your Router?

You will use the bits with routers. But what if the bits are not compatible with the routers?

Make sure the bits are compatible with your routers. Look at the size, flute, edges, and shank sizes for compatibility. Some bits are only compatible with table-mounted routers whereas some are good with regular routers. Know the compatibility before picking one.

Consider The Construction

The materials the bits are made with play a vital role in durability, strength, and heat build-up. You do not want to have your bits broken during sign making. It is also disappointing to have burned the surface.

Solid carbide works really well, especially when you are working with hardwood. It offers superior strength and durability. But you will not get enough precision with the carbide.

Carbide-tipped can solve this problem. You can put a lot of pressure on it and get excellent precision. But you know, more sugar is necessary to make your juice sweeter. You have to invest more in this expensive construction.

Steel can work if your budget is limited. But you must sacrifice the precision and durability you can get from Carbide-tipped or carbide bits.

Do Not Ignore Shank Diameter Size

The shank diameter is important for precision. ¼ is most common but ½ will provide more stability and grip for less deflection. Make sure your router is compatible with it. Otherwise, go for the ¼ one. Also, ¼ is suitable for carving and other woodworking within budget.

Are You a Newbie?

Consider your woodworking experience. Not all types of bits are suitable for newbies and pros. You need to understand your level of expertise and pick one that can match your expertise.

Experts can handle any bits and bring good results. But you cannot as a newbie. Make sure the bits have an anti-kickback design to prevent overfeeding and accidents.

Ideal Core Material for Router Bits

It is vital to consider the material of router bits before making a purchase decision. They are designed to withstand heavy forces. Experts agree that the best router bits for sign making are made of carbide as they promise prominence, convenience, and efficiency.

Solid carbide bits ensure the maximum robustness in router bits. Solid carbide should be the best pick for you if you’re dealing with hardwoods.

If you’re looking for blades with very sharp edges, carbide-tipped bits will be the way to go. They can stand against the heavy intensity and high speeds.
