Can Router Bits Cut Metal?

Router bits are widely used in woodworking to create intricate designs, shape edges, and cut various materials. But can router bits cut metal? This question often arises when considering the versatility of these tools. In this article, we will explore the capabilities of router bits when it comes to metalworking and discuss the factors that can affect their performance. Whether you’re a professional woodworker or a hobbyist looking to expand your tool repertoire, understanding the possibilities and limitations of using router bits on metal can be valuable knowledge.

The Capabilities of Router Bits for Metalworking

When it comes to cutting metal, router bits are not specifically designed for this purpose. In general, their primary function is to shape and cut wood, plastic, and other soft materials. However, with the right adjustments and precautions, router bits can sometimes be used for light metalworking tasks. Here are some key points to consider:

1. Bit Material and Coating

The material and coating of the router bit play a crucial role in determining its effectiveness for cutting metal. Most router bits are made from high-speed steel (HSS) or carbide. While HSS bits are more affordable, carbide bits are known for their durability and ability to withstand high temperatures. Additionally, some router bits are coated with materials like titanium nitride (TiN) or diamond particles to enhance their performance and extend their lifespan.

When it comes to cutting metal, it is recommended to use carbide-tipped router bits. These bits have a small piece of carbide brazed or welded onto the cutting edge, which provides increased hardness and resistance to heat. Carbide bits can effectively cut through soft alloys, such as aluminum or brass, but may struggle with harder materials like steel. Therefore, it’s important to choose the appropriate bit for the type of metal you intend to work with.

2. Router Speed and Feed Rate

The speed and feed rate of the router are other crucial factors that can affect the performance of router bits when cutting metal. It is generally recommended to operate the router at a slower speed when working with metal materials. Higher speeds can cause the bit to heat up quickly and diminish its lifespan. Additionally, using a higher feed rate with metal can put excessive stress on the bit, leading to poor performance and potential breakage.

It’s important to adjust the router settings according to the type and thickness of the metal being worked on. Experimenting with different speeds and feed rates can help achieve optimal results while maintaining the longevity of the router bit.

3. Proper Cooling and Lubrication

Cutting metal generates a significant amount of heat, which can be detrimental to the router bit and the material being cut. To prevent overheating and ensure better performance, it’s essential to provide proper cooling and lubrication during the metalworking process. This can be done by using a coolant or cutting fluid specifically designed for metalworking.

Applying a coolant or lubricant to the cutting area helps dissipate heat and reduces friction, allowing the router bit to make smoother and cleaner cuts. Additionally, it prolongs the life of the bit by preventing excessive wear and tear. When using a coolant, be sure to follow the manufacturer’s instructions and take necessary safety precautions.

4. Safety Precautions

Working with router bits on metal requires special safety precautions. Metalworking can produce sharp metal chips and sparks, which can be hazardous. Therefore, always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and respiratory protection. It’s also advisable to secure the metal piece firmly in place and use clamps or a vice to prevent any movement during the cutting process.

It’s important to note that while router bits can be used for light metalworking tasks, they are not suitable for heavy-duty metal cutting applications. For large-scale metalwork, it’s best to use dedicated metalworking tools such as a metal cutting bandsaw or a plasma cutter.

Router Bits vs. Metalworking Tools

Router bits, although versatile, have their limitations when it comes to cutting metal. While they can be useful for small, intricate metalworking projects or working with soft metal alloys, they are not designed or optimized for heavy-duty metal cutting. For larger and more demanding metal cutting tasks, specialized metalworking tools are the better choice.

Some popular metalworking tools include:

1. Metal Cutting Bandsaw

A metal cutting bandsaw is specifically designed for cutting metal. It features a toothed blade that moves in a continuous loop and is available in various sizes. Metal cutting bandsaws are capable of making straight or curved cuts with precision, making them suitable for a wide range of metal fabrication tasks. They are commonly used in industrial settings but are also available in smaller sizes for home workshops.

2. Plasma Cutter

Plasma cutters use a high-velocity jet of ionized gas to cut through metal. They are highly effective for cutting various types of metal quickly and accurately. Plasma cutters are commonly used in metal fabrication, automotive repair, and other heavy-duty metalworking applications. They offer superior speed and precision compared to other metal cutting methods.

3. Angle Grinder with Cutting Disc

An angle grinder equipped with a cutting disc is another common tool used for cutting metal. It is handheld and versatile, making it suitable for small-scale metal cutting tasks. When using an angle grinder, it’s important to wear proper protective gear and be cautious, as the cutting disc can generate sparks and kickback.

While router bits can be a valuable addition to a woodworker’s toolkit, they should not be relied upon as the primary choice for metalworking tasks. Understanding the limitations of router bits and investing in appropriate metalworking tools will help ensure a safer and more efficient metal cutting experience.


In conclusion, router bits can be used to cut metal, but their effectiveness and suitability depend on various factors such as bit material, feed rate, cooling, and lubrication. While they may be suitable for small-scale and light metalworking projects, dedicated metal cutting tools like metal cutting bandsaws and plasma cutters are better suited for heavy-duty cutting tasks. It’s important to understand the capabilities and limitations of router bits when it comes to working with metal, and to prioritize safety by using proper protective equipment and following recommended guidelines. By doing so, you can expand your woodworking possibilities while ensuring a successful metalworking experience.

Using a router with variable speed settings can also be beneficial, as it allows you to adjust the speed to match the specific metal you’re cutting.

Additionally, using a sturdy router table or clamp to secure the workpiece is highly recommended when cutting metal with a handheld router. This helps ensure stability and allows for more controlled and accurate cuts. Always follow the manufacturer’s guidelines and recommendations when using a router for metal cutting.

4. Are there any specific safety precautions when using router bits for metal cutting?

When using router bits for metal cutting, it’s essential to take proper safety precautions. Metal cutting can produce sparks and hot chips, so wearing protective goggles, gloves, and a long-sleeved shirt is strongly advised. This protects your eyes, hands, and skin from any potential injuries. Additionally, ensure that the work area is well-ventilated to prevent the buildup of fumes or dust.

Always follow the manufacturer’s instructions for the specific router bit you’re using, including recommended cutting speed, feed rate, and depth of cut. These guidelines help prevent overheating, premature wear on the bit, and possible accidents. Remember, safety should be your top priority when working with power tools and cutting metal.

5. Can a router bit be used to cut metal in intricate shapes or designs?

Yes, a router bit can be used to cut metal in intricate shapes or designs, thanks to the precision and versatility of routers. Router bits with various profiles, such as chamfer bits, cove bits, or roundover bits, can create decorative edges or shapes on metal surfaces. This allows you to add artistic details or embellishments to your metalwork projects.

However, it’s crucial to keep in mind that the depth of cut and feed rate should be carefully controlled to achieve the desired results. Metal cutting with a router requires patience, precision, and practice to ensure clean and accurate cuts, especially when working on intricate designs. Make sure to secure the workpiece properly and take your time to achieve the best possible outcome.
