Table of Contents - Best Hacksaw Blade for Metal

Hacksaw blades come in all different sizes, shapes, and brands – it can be challenging to know what hacksaw blade you need! Craftsmen have used hacksaws for years because they allow cuts on job sites where power tools cannot go due to safety concerns. 

There are, however, specific hacksaw blades used for cutting different materials, so attention to detail is needed when selecting the hacksaw right for your job.

To help ease the search process, the team at Cleaning King has put together this hacksaw blade guide that covers everything from choosing your hacksaw blade material to finding out when you should replace your hacksaw blades. Additionally, we’ll cover some information on the blades that should be used for different materials and why.

What to Look for When Choosing a Hacksaw Blade

When choosing hacksaw blades, the main thing to look for is whether you need a metal hacksaw blade or a diamond-tipped hacksaw blade. These two choices will determine what type of material your hacksaw blades can be used on and how long they last.

Another critical factor in determining which hacksaw blades are right for your job is looking at the teeth per inch (TPI). This number determines how quickly and efficiently your hacksaws cut through different materials. It’s usually best to choose a higher TPI rating when cutting harder metals like:

  • Stainless steel
  • Cast iron
  • Brass alloy
  • Copper alloy
  • Aluminum alloys

In these cases, selecting from between 18TPI up to 30TPI should yield satisfactory results depending on how clean you want the hacksaw cut. 

If the hacksaw is cutting softer materials like plastic or wood, then it’s best to select 12TPI up to 18TPI for hacksaws blades that are able to get through these types of material more easily and in a shorter amount of time.

TPI (teeth per inch / 25mm of blade)

Suggested usage


Large profiles, aluminum, softer metals


General workshop projects


Steel plate up to 5/6mm thickness


Hollow sections and steel tubing

When considering all factors on which hacksaw blade would be most effective, make sure not to overlook your own skill level when making this decision. 

If you’re an experienced metal cutter with plenty of practice under your belt, chances are selecting from between 25TPI up to 30TPI will work well since they require less effort by hand while still getting through harder metals quickly without sacrificing quality. 

On the other hand, if you’ve never used hacksaws before, hacksaw blades between 15TPI up to 18TPI are a great choice because they require less effort on your part and will still get through metal smoothly.

What Are the Leading Hacksaw Blade Brands?

The best overall hacksaw and hacksaw blade brand is the Lenox brand. They are made in the USA, and they’re known for their incredible hacksaw blade durability. Some other leading hacksaw blade brands include: 

  • Albrecht hacksaw blades
  • Bahco hacksaw blades
  • Irwin hacksaw blades
  • MK Morse blades

The Lenox High-Tension Hacksaw, for example, has a unique I-beam design that allows blades to tension up to 50,000 psi, resulting in fast, straight cuts. Even in damp and chilly environments, the rubberized handles allow for confident handling. 

The Lenox hacksaw blades may be used as a jab saw and stores up to 5 extra 12-inch hacksaw blades in the I-beam. All hacksaws include one 12-inch 24 TPI hacksaw blade for immediate use.

Another great hacksaw brand is the Craftsman hacksaw, which also offers blades that will cut through metal like butter! The only downside to this brand is it does not include any guides or clamps with its products.

How Long Should a Hacksaw Blade Last for?

Hacksaw blades can survive for months, even a year, before needing to be replaced or upgraded.

Depending on the materials you use the blades on, the hacksaw blade may need to be replaced sooner rather than later.

What Types of Hacksaws for Metal Are There? 

The most common type is the standard hacksaw that has a metal frame with an adjustable blade clamping system on each side. Some other types include hacksaws that are foldable or come with ergonomic handles to reduce fatigue while cutting through metals over extended periods of time.

How to Cut Metal with a Hacksaw

Cutting metal with a hacksaw can be an intense and often dangerous process.  The hacksaw blades should be kept sharp and in good condition to ensure the sawing is done safely.

Assemble Your Hacksaw Correctly

One of the most important steps when cutting metal with a hacksaw blade, which can easily be overlooked, is assembling the hacksaw correctly before use. This process ensures that users will get optimal performance from their hacksaws and prevent accidents from occurring.

The hacksaw frame should be held firmly in place.  The hacksaw blade must then be placed into the hacksaw frame and tightened by turning it clockwise, which is opposite to how screws are turned for safety purposes.

Hacksaws need to stay sharp, so they can effectively cut through metal without getting stuck or breaking apart. Regularly rinsing hacksaw blades with water and oiling the frame is a great way to keep hacksaws in good condition.

Hacksaws should never be left sitting in water because this will cause them to rust more quickly. It also corrodes hacksaw frames over time as well as dulls the blade itself. Instead, after each use, hacksaws must have their teeth dried off using a dry cloth or paper towel before being stored away until next time.

Choose the Correct Blade for Metal Cutting 

The right hacksaw blade for metal cutting will be one that is right for the material that needs to be cut. The hacksaw blades are made out of different materials, including carbon steel and high-speed steel.

Carbon Steel hacksaw blades should be used on metal cutting applications that do not require precision or accuracy because they cannot stay sharp very long. 

High-Speed Steel hacksaw blades can stay sharp longer and are ideal for metal cutting. 

Another thing to consider when choosing hacksaw blades for metal cutting is the number of teeth per inch (TPI) it has. The higher the TPI hacksaw blade, the smoother and more precise the cut will be. However, this also means that you need fewer strokes because there are fewer gaps between each tooth.

The correct TPI for Metal cutting is: 

  • 14TPI for Large profiles, aluminum, softer metals.
  • 24 TPI for Steel plate up to 5/6mm thickness
  • 32 TPI for Hollow sections and steel tubing

When cutting through thicker material out of metal using hacksaw blades, having an increased TPI can help reduce hand strain. 

Prepare For Metal Cutting with a Hacksaw

When cutting metal, wear eye protection and gloves at all times. This gear will protect you from the sharp ends of freshly cut metal. 

Prepare the workpiece by clamping it in place securely so that you can cut with little effort. 

When using hacksaw blades for light metal cutting tasks, always use your arm rather than bodyweight to apply force while pushing through the material being cut. 

When doing heavier material removal or working on overhead projects, secure yourself with an appropriate support structure so that both of your arms are free to power through each stroke without straining anything but the hacksaw blade itself! 

Use the Hacksaw Properly When Cutting Metal

To begin the cut, make a series of one-way strokes in the direction of the teeth to create a narrow incision that the blade can sit in. Once the blade has cut into the metal at least one millimeter or two, it will be able to saw completely forward and backward.

When cutting, try not to rush; use a slow, consistent sawing motion to get the best cut and minimize the chance of the blade overheating and breaking. To reduce friction, use a little bit of machine oil or cutting fluid on the blade.

Is There Anything Different Required for Different Types of Metal?

The TPI of your hacksaw blade is the main thing that differs when cutting different types of metal. A hacksaw blade with a higher TPI will cut through metal faster than one with fewer teeth per inch. If you are cutting thicker pieces of metal, it is best to use blades that have more teeth, so the hacksaw does not overheat and break. For thinner metals, fewer Teeth Per Inch (TPI) can be used without overheating.

What is the Best Way to Brace Metal for Cutting?

The best way to brace metal for cutting is to use hacksaw horses. They are sturdy enough to support the metal, regardless of where it is being cut. This can allow you to focus on making a precise slice through the metal’s surface instead of holding onto something that could slip or move at any moment.

Use clamps for larger pieces of metal. This will ensure that the metal does not shift or move when cutting.

When you are working with thin pieces of metal, it is possible to cut them without bracing at all by holding onto them yourself. However, this can be dangerous and lead to slippage or cuts in your skin. Instead of using hacksaw horses for smaller metals, place a piece of scrap wood on top of the hacksaw horse so that they do not slip off while cutting. 

Here are some of the most frequently asked questions about cutting different materials with a hacksaw, the details of hacksaw blades, and what goes into choosing the right blade. 

Can a Hacksaw Cut Through Steel?

Hacksaws can cut through various materials, including steel. 

However, depending on the size of metal you are cutting and what blade is in your hacksaw, it may or may not be challenging to do so. To choose the correct blade for cutting steel, look at the TPI of the blade.  

If the blade has a low TPI, it will not be able to cut through steel. You’ll want to choose a hacksaw blade with at least 20 TPI for cutting metal like steel and stainless steel. 

How to Change a Hacksaw Blade

Changing hacksaw blades is easy and can be done in a matter of minutes. 

  • First, you’ll need to remove the blade from the hacksaw frame by loosening it with your hands. Loosen the wing nut near the handle, then remove it. Hacksaw blades are held in with tension, so they may be difficult to remove. 
  • Then place a new hacksaw blade into the hacksaw frame so that it locks into place. Install a new blade onto the retaining pins, then tighten the wing nut by rotating it clockwise until the blade is tight.
  • Make a test cut on a piece of scrap metal held in a vise to ensure that you’ve fitted the hacksaw blade correctly and tightened it down enough. 

You should replace hacksaw blades when they become dull. Hacksaw blades typically last for ten to twenty uses. When hacksaw blades are replaced, the blade tension may need to be checked once more.

To prolong hacksaw life, keep them clean and store them inside their carrying case for protection from debris and dust buildup between uses.

How Do You Tension a Hacksaw?

To tension, a hacksaw blade, start by removing the hacksaw blade from the saw frame. 

Next, add a hacksaw tensioning tool to hold the hacksaw blade in place while tightening it onto its frame. With both hands on either side of your hacksaw frame’s screw head and on hand behind the hacksaw handle for control, tighten down a wing nut until you feel resistance or until it is very tight against a hacksaw blade that has been secured into position using a hacksaw tensioning tool. 

Make sure not to over-tension your metal cutting hacksaws, as this can cause them to snap during operation. 

If you are struggling to make hacksaw blades sit in line together, there may be an issue with the tensioning tool itself – check whether it is the correct size for your blade. If not, then use a different hacksaw frame when tightening down hacksaws into place using this tool. 

When finished cutting through metal materials with your hacksaw blade, release its tension using your hacksaw’s wing nut before removing and replacing any old blades that no longer work as they should. Replace them immediately if their teeth appear worn or bent out of shape because one might snap during operation sooner rather than later.
