Can a hacksaw cut metal? - Fix It Cape Town

When it comes to cutting metal, one of the most common hand tools that comes to mind is the hacksaw. Simple yet effective, a hacksaw is a versatile tool that can be used in various metalworking applications. In this guide, we will cover the features and limitations of this hand tool, to help you make an informed decision about using a hacksaw for your metal cutting needs.

Understanding the Hacksaw

A hacksaw typically consists of a frame and a replaceable blade. The frame is usually made of metal or plastic and has a handle at one end. The replaceable blade, which is available in different types and sizes, is attached to the frame. The blade features a series of small, sharp teeth that are designed to cut through metal with ease.

Features of a Hacksaw

Here are some key features of a hacksaw that make it a popular choice for cutting metal:

  1. Versatility: Hacksaws can be used to cut a wide range of metals, including steel, aluminum, brass, and even some types of stainless steel. This versatility makes it an essential tool for metalworkers, DIY enthusiasts, and professionals alike.
  2. Portability: Due to its compact size and lightweight design, a hacksaw is easy to carry and maneuver. This makes it a convenient tool for on-site metal cutting tasks or when working in tight spaces.
  3. Cost-effective: Comparing the cost of a hacksaw to other power tools used for metal cutting, it is significantly more affordable. This makes it an economical choice, especially for occasional or small-scale metal cutting needs.
  4. Control: Using a hacksaw gives the operator greater control over the cutting process. With its manual operation, you can adjust the speed and pressure applied while cutting, ensuring precision and accuracy.
  5. Ease of use: Hacksaws are relatively easy to use, making them suitable for both beginners and experts. They do not require any special training or specific expertise to achieve a clean and straight cut.

Limitations of a Hacksaw

While a hacksaw offers numerous advantages, it also has certain limitations that are important to consider before using it for your metal cutting tasks:

  1. Cutting speed: Compared to power tools such as angle grinders or plasma cutters, hacksaws have a slower cutting speed. This can make them less efficient for large-scale cutting projects or when time is a constraint.
  2. Physical exertion: Using a hacksaw requires physical exertion, especially when cutting through thicker or harder metals. The repetitive motion involved in sawing can be tiring, and it may not be suitable for individuals with certain physical limitations.
  3. Material limitations: While hacksaws can cut through a wide range of metals, they may struggle with extremely thick or hard materials. In such cases, alternative cutting methods or tools may be more appropriate.
  4. Accuracy: Achieving a perfectly straight and clean cut with a hacksaw requires skill and practice. The saw blade can easily wander off course, resulting in a crooked cut or rough edges.
  5. Limited blade life: Hacksaw blades have a limited lifespan and need to be replaced when they become dull or worn out. This adds to the overall maintenance cost of using a hacksaw.


Q1. Can I use a hacksaw to cut other materials besides metal?
Yes, hacksaws can also be used to cut certain materials such as plastic, wood, and even some types of composite materials. However, it is important to select the appropriate blade for each material to ensure clean and efficient cuts.

Q2. How do I choose the right hacksaw blade for my metal cutting task?
The choice of hacksaw blade depends on the type and thickness of the metal you are cutting. For general-purpose cutting, a blade with 18 to 24 teeth per inch (TPI) would suffice. Higher TPI blades are used for finer cuts, while lower TPI blades are suitable for cutting thicker metals.

Q3. Can I use a power tool instead of a hacksaw for cutting metal?
Yes, power tools such as angle grinders, reciprocating saws, or plasma cutters can be used for metal cutting. These tools offer faster cutting speeds and are more suitable for heavy-duty or large-scale metal cutting projects. However, they may not be as versatile or cost-effective as a hacksaw for smaller tasks or occasional use.


A hacksaw is a valuable hand tool for cutting metal due to its versatility, portability, and cost-effectiveness. It allows for greater control, ease of use, and can cut a wide range of metals. However, it is important to consider its limitations, including slower cutting speeds, physical exertion required, and material limitations. By understanding the features and limitations of a hacksaw, you can make an informed decision about using this essential tool for your metal cutting needs.
