What Is The Gap In A Saw Blade Called?

A saw blade is an essential tool for woodworking, metalworking, and construction tasks. It is a circular-shaped blade that is attached to a saw machine, which is used to cut through different materials. A saw blade consists of a body, teeth, gullet, and a gap. The gap in a saw blade is an important feature that plays a vital role in determining the cutting performance of the blade. In this article, we will discuss in detail what the gap in a saw blade is called and its significance.

What Is The Gap In A Saw Blade Called?

The gap in a saw blade is called the kerf. It is the width of the slot that is cut by the saw blade while making a cut. The kerf is wider than the blade itself, which allows the blade to move freely and prevent it from getting stuck or binding during the cut. The kerf is a crucial feature in a saw blade, and it is essential to choose the right kerf size for the material being cut.

Why Is The Kerf Important?

The kerf is an important factor that determines the cutting performance of a saw blade. A wider kerf requires more power to make a cut, but it produces a cleaner cut with less burning and less chance of binding. A narrower kerf requires less power to make a cut, but it produces a rougher cut with more burning and more chance of binding.

Choosing the right kerf size is essential for achieving the desired cutting results. The kerf size depends on the type of material being cut, the thickness of the material, and the type of saw being used. For example, a saw blade with a wider kerf is suitable for cutting thicker materials, while a saw blade with a narrower kerf is suitable for cutting thinner materials.

Types of Kerf

There are two types of kerf – full kerf and thin kerf. Full kerf blades have a wider kerf and require more power to make a cut. They are suitable for cutting thicker materials, such as hardwoods, and are commonly used in table saws and radial arm saws. Thin kerf blades have a narrower kerf and require less power to make a cut. They are suitable for cutting thinner materials, such as softwoods and plywood, and are commonly used in circular saws and miter saws.

Conclusion

The gap in a saw blade, also known as the kerf, is an important feature that determines the cutting performance of the blade. Choosing the right kerf size is essential for achieving the desired cutting results. The kerf size depends on the type of material being cut, the thickness of the material, and the type of saw being used. There are two types of kerf – full kerf and thin kerf – each suitable for different materials and saws. Understanding the significance of the kerf in a saw blade can help in selecting the right blade for the job and achieving the desired cutting results.

Frequently Asked Questions: What Is The Gap In A Saw Blade Called?

What is the purpose of the gap in a saw blade?

The gap in a saw blade, also known as the gullet, is designed to provide space for sawdust and other debris to escape from the cut. This prevents the saw blade from becoming clogged and overheating, which could cause damage to the blade and the material being cut.

How is the size of the gap determined?

The size of the gap in a saw blade is determined by the thickness of the material being cut and the number of teeth on the blade. The larger the teeth on the blade and the thicker the material being cut, the larger the gap needs to be to allow for proper debris removal.

What are the different types of gaps in saw blades?

There are two main types of gaps in saw blades: standard and alternate top bevel (ATB). Standard gaps are typically found on rip blades and have a square or rectangular shape. ATB gaps are found on crosscut blades and have a more pointed shape that helps to create a smoother cut on the material being cut.

Do all saw blades have a gap?

Not all saw blades have a gap. For example, dado blades and molding cutters do not have a gap because they are designed to make very precise cuts and do not produce a lot of debris. However, most saw blades used for general cutting purposes will have a gap to allow for proper debris removal.
