Why Do You Hammer A Saw Blade?

When it comes to using saw blades, you may have heard of a process known as hammering. But why exactly do you hammer a saw blade? In this article, we will dive into the reasons behind this technique and how it can benefit your sawing projects.

What is Hammering?

Hammering a saw blade involves reshaping the blade’s teeth to optimize its performance. This technique can be done by hand or by using a specialized hammering machine. The process involves flattening the tops of the saw blade’s teeth while also angling the tips slightly to create a sharp cutting edge.

Why Do You Hammer a Saw Blade?

The primary reason for hammering a saw blade is to increase its cutting efficiency. By reshaping the teeth, the blade is better suited for cutting through tough materials such as hardwoods, metal, and plastics. Additionally, the angled tips of the teeth allow for smoother and more precise cuts.

Hammering a saw blade can also help prolong its lifespan. Over time, saw blades can become dull or damaged due to regular use. Hammering can restore the blade’s sharpness, making it more effective and reducing the need for frequent replacements.

Types of Saw Blades That Benefit from Hammering

While not all saw blades require hammering, certain types are more suited for this technique. These include:

Circular saw blades

Bandsaw blades
Jigsaw blades
Hand saw blades

If you use any of these types of saw blades regularly, hammering can greatly improve their performance and longevity.

Choose the right hammering machine or tool. There are various types of hammering machines available, each suited for different types of saw blades. Make sure you choose one that’s suitable for your blade.

Clean the saw blade thoroughly. Before hammering, make sure your saw blade is free from any dirt, debris, or rust. You can use a wire brush or sandpaper to clean it.
Secure the blade. Use clamps or a vise to hold the saw blade in place while hammering. This will help prevent any accidental injuries.
Hammer the blade. Follow the instructions provided with your hammering machine or tool. Generally, you’ll need to apply pressure to the blade’s teeth with the hammering tool, flattening them and angling the tips slightly.

Check the blade’s sharpness. After hammering, check the blade’s sharpness by running your finger along the teeth. If they feel smooth and even, the blade is ready to use.
