Know About the Circular Blades

For changing circular saw blade, an appropriate circular saw blade must be used in order to achieve the best cutting results and to extend the life of the blade. Circular saw blades are not universal; they come in a variety of shapes and sizes, each optimized for cutting a particular kind of material.

To further understand why it matters so much, let’s delve into this aspect:

Count of teeth

The quality of the cut is significantly influenced by the number of teeth on a circular saw blade. For finishing work or slicing through delicate materials like plywood or laminate, blades with more teeth offer finer, smoother cuts. On the other hand, blades with fewer teeth are made for rougher, quicker cuts, making them ideal for slicing through heavy, solid lumber or for framing. This is a very crucial step to change blade on circular saw.

Blade Dimensions

Different diameters of circular saw blades are available, with 7-1/4 inches being the most popular size for handheld circular saws. How far into the material the blade can cut depends on its diameter. Larger blades can handle thicker materials, while smaller ones are best for lighter tasks. This information will help you learn how to change blade on circular saw in an accurate way.

Blade Design

Varying teeth patterns for blades include:

Rip Blades

These blades, which have fewer teeth, are made for long, parallel cuts made with the wood’s grain. They can generate harsher edges, but they excel at cutting rapidly with the grain. Check blade type before changing circular saw blade.

Crosscut Blades

Crosscut blades are better for cutting against the grain of wood because they have more teeth. They result in cuts that are cleaner and splinter-free.

Combination Blades

These blades balance speed and smoothness in a variety of woodworking jobs. They are made for both ripping and crosscutting. Check blade type before changing circular saw blade.

Blade Material

Different materials require different blade materials to achieve efficient and clean cuts. Here are some common blade materials and their uses:
