Tools you’ll need to cut aluminum angle

1. Miter saw or chop saw

A miter saw is designed to make precise cuts at various angles and is ideal for making accurate cuts for frames or corners. On the other hand, a chop saw is designed to make perpendicular, straight cuts and is great for cutting thicker pieces of aluminum angle. Ultimately, the choice between two saws will depend on the specific requirements of your project.

2. Blade suitable for metal cutting

When it comes to cutting metal, including aluminum angle, a blade with carbide teeth is generally the most suitable option. These blades can withstand the hardness of metal and provide clean and accurate cuts.

Other types of blades, such as abrasive blades, can also be used, but they tend to wear out more quickly and produce a lot of sparks and heat, which can damage angles and create a safety hazard. Always ensure that the blade you use is suitable for cutting the metal and follow appropriate safety measures.

3. Safety goggles or face shield

Both glasses and shields are important forms of eye protection when you cut aluminum angles or any other material. Safety goggles are a minimum requirement and provide protection against small debris and metal shavings. Face shields offer additional protection, covering not only the eyes but also the face and neck from flying debris, sparks, and heat.

4. C-clamp

A C-clamp is commonly used when cutting angles or any other material.

It is a versatile tool that can be used to hold the material securely in place, preventing it from moving during cutting.

This helps ensure accurate and straight cuts and also minimizes the risk of injury by keeping the material stable. C-clamps are available in various sizes and designs and can be used with a range of cutting tools, including miter saws, chop saws, and angle grinders.

Cut aluminum angles

Now, it’s time to make the cut. Depending on the type of saw you have, you’ll need to follow the appropriate steps:

  • Hacksaw: Implementing a hacksaw is one of the options to use to cut aluminum angles. The blade is placed on the mark you made. Then start sawing back and forth, applying steady pressure.Keep the blade perpendicular to the angle to secure a straight cut. You should use lubricant on the blade to keep it from overheating or getting stuck.
  • Miter saw: If you have a miter saw, it’s a great option for making precise cuts. The angle of the blade is adjusted to match the angle you want to cut, then the aluminum angle is placed on the table saw and the cut is made.
  • Circular saw: This saw can be utilized by equipping it with a blade specifically designed for cutting aluminum. It is important to ensure that the blade is both sharp and suitable for cutting through aluminum.Clamp the aluminum angle to a work surface and slowly guide the blade along the marked line.
