What tool cuts thick steel? - Fix It Cape Town

When it comes to cutting thick steel, having the right tool for the job is essential. Thick steel can be extremely difficult to cut through, and using the wrong tool can result in inefficiency, frustration, and even damage to the material. In this guide, we will explore the different tools available for cutting thick steel and provide tips and advice to ensure you choose the right one for your needs.

Types of Tools for Cutting Thick Steel

  1. Angle Grinder: An angle grinder is a versatile power tool that can be used for various applications, including cutting through thick steel. It utilizes a rotating disc or wheel to make precise cuts in the metal. Angle grinders are available in different sizes and power ratings, allowing you to choose the one that suits your specific requirements.

  2. Plasma Cutter: A plasma cutter is an efficient tool for cutting through thick steel. It works by creating a high-temperature plasma arc that melts the metal, allowing for a smooth and clean cut. Plasma cutters are capable of cutting through steel of varying thicknesses and are often used in industrial settings.

  3. Oxy-Fuel Torch: An oxy-fuel torch, also known as a cutting torch, uses a mixture of oxygen and a fuel gas, such as acetylene, to create a high-temperature flame. This flame can cut through thick steel by melting it along the cutting line. Oxy-fuel torches are commonly used in metal fabrication and welding industries.

  4. Circular Saw with Metal-Cutting Blade: A circular saw equipped with a metal-cutting blade can also be used for cutting thick steel. This tool is versatile and portable, making it a convenient choice for smaller projects or on-site cutting. However, it may not be as efficient as other tools when it comes to cutting thicker steel.

  5. Abrasive Saw: An abrasive saw, also known as a cutoff saw or cold saw, utilizes a rotating blade with abrasive particles to cut through various materials, including thick steel. These saws are specifically designed for metal cutting and can provide clean and accurate cuts. However, they may generate sparks and produce a significant amount of noise during operation.

Tips for Choosing the Right Tool

  1. Consider the Thickness of the Steel: The first thing to consider when choosing a cutting tool is the thickness of the steel you need to cut. Some tools, such as plasma cutters and oxy-fuel torches, are more suitable for thicker materials, while others, like angle grinders and circular saws, may be better suited for thinner steel.

  2. Evaluate Your Project Requirements: Determine the specific requirements of your project, such as the type of cut needed (straight, curved, or intricate), the level of precision required, and the overall size of the material. This will help you select a tool that can handle your project efficiently and effectively.

  3. Consider Safety Precautions: Cutting thick steel can be hazardous, so it’s important to consider safety precautions when choosing a tool. Look for safety features such as blade guards, thermal overload protection, and ergonomic designs that minimize the risk of accidents and operator fatigue.

  4. Budget and Cost: Consider your budget and the overall cost of the tool, including any additional equipment or accessories required. While some tools may have a higher upfront cost, they could save you time and money in the long run, thanks to their efficiency and durability.


Q: Can I use a regular hacksaw to cut thick steel?

A: While a hacksaw can be used to cut through steel, it is best suited for thinner materials. It may take a significant amount of time and effort to cut through thick steel using a regular hacksaw.

Q: Which tool is the fastest for cutting thick steel?

A: Plasma cutters are generally the fastest tools for cutting thick steel. They utilize high-temperature plasma arcs that quickly melt through the metal, ensuring efficient and clean cuts.

Q: Do I need special training to use an oxy-fuel torch?

A: Oxy-fuel torches require proper training and knowledge to operate safely. The high-temperature flame produced by the torch can be dangerous if not handled correctly. It is recommended to receive training or consult with a professional before using an oxy-fuel torch.

Q: Are there any safety precautions I should take when cutting thick steel?

A: Yes, regardless of the tool chosen, always wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and a face shield. Ensure the work area is well-ventilated to minimize exposure to fumes or sparks. Additionally, read and follow the manufacturer’s instructions and safety guidelines for the specific tool you are using.


Cutting thick steel requires the right tool for the job. The choice of tool depends on the thickness of the steel and the specific requirements of your project. Whether you opt for an angle grinder, plasma cutter, oxy-fuel torch, circular saw, or abrasive saw, ensuring safety measures and taking into account your budget and cost will help you make an informed decision. Always follow the manufacturer’s instructions and safety guidelines to ensure accurate and efficient cutting of thick steel.
