Did you know?
A circular saw with blades and handles, used for cutting material, such as wood.
It is rarely used for cutting metals.
Cutting is done by placing the tip of the teeth against the material and moving it forward forcefully or continuously.
You might be mistaken and think there’s not much to know before purchasing a blade for a circular saw, table saw, or radial arm saw, but when you look at it, your choices can be daunting.
Therefore, we would recommend getting to know some basic terms about blade materials, tooth types, and other technical things.
Here are some terms and considerations you need to know when choosing a blade:
Application? You also need to know what type of saw you are going to use the blade on and what types of materials you are going to cut.
Different circular saws and materials require (or perform best) with blades adapted to this operation.
There are general-purpose blades that can handle different materials, but if you know you’re only going to cut (or mostly) one type, buy a blade that’s designed for that.
?Number of Teeth – The amount of teeth on a blade determines its cutting action. More teeth means a smoother cut, fewer teeth means the blade removes more material.
Cross-cut saw blades have more teeth and make smoother cuts across the grain of the material, rip saw blades have fewer teeth, are optimized to cut with the grain and remove much more material.
The dimple refers to the space between each tooth on the blade.
A wider socket produces a larger chip of material cross-section.
Tooth configuration – Does the shape of the blade’s teeth also determine its performance?
Teeth are configured to optimize cross-cutting, ripping and working through certain materials, such as laminate, MDF, etc.
Some common tooth types include Flat Top (FT), optimal for tearing,
Alternative Top Bevel (ATB), optimal for cross cutting,
Combined tooth (CT), which includes both types of teeth and is intended for general-purpose cutting.
?Tooth Angle – The tooth (or hook) angle refers to the angle of the tooth in relation to the centerline of the blade. Blades with a “positive angle” mean that the teeth are angled forward by a specified amount. A “negative hook angle” means that the teeth are pointed backward, opposite the direction of blade rotation. The higher the positive angle of the blade, the more aggressive the blade.
