The table saw is a tool that is crucial to the cutting industry, particularly the lumber processing industry.
These components include the table saw blade, the extension wings, miter gauge, and arbor assembly. All these components are crucial for the functioning of the device.
In this article, we will carefully navigate around the table saw blade. We will also focus on its applications and the different factors surrounding this blade’s use.
Section 1: What is a Table Saw Blade?
The table saw blade is the essential part of a table saw. It is the cutting part of the table saw. Table saws blades consist of different materials like stainless steel, tungsten, and sometimes even carbide. You can use the table saw blade to cut different materials ranging from lumber to sheet goods.
1.1 What Table Saw Blade use?
Different types of table saw blades exist, and these blades have unique features that make them suitable for different cutting purposes. You will need to have a clear understanding of different factors before choosing the blade to use.
An essential factor to consider is the type of cut. Rip cuts and crosscuts are the two populous types of cutting available today. However, not all blades can make these cuts. Some blades can make rip cuts, while others can make crosscuts. Besides, some blades can cut both styles. On some peculiar occasions, there are specialized blades you can use for specific materials or applications. These make a solid case to first have a good knowledge of saw blades and the type of cut you need.
1.2 Why Choose the Table Saw Blade?
Most users aim to have the best blade to smooth and effectively cut woodworking and other cutting practices. They require a blade that satisfies both economic and performance criteria. The table saw blade is one of such blades.
Some table saw blades often come at a steep price but make up for their precision and durability. More so, another vital reason for owning a table saw blade is because of their wide cutting range. Table saw blades are applicable for cutting a vast amount of materials smoothly.
Section 2: Type of Table Saw Blade.
It is also essential to also have at arm’s length different types of table saw blade. These four main blade types are;
2.1 Ripping Blades:
The ripping blades are synonymous to rip cuts. As you know, a rip cut is a woodworking cutting type where you cut along the grain of the workpiece. Most users refer to this cutting style as ‘Ripping.’ You should know that the ripping blades are fairly popular, and their unique teeth configuration makes them favorites for cutting stock.
Ripping Saw Blade
These blades often come with a 20-teeth configuration with wide gullets. This configuration makes them suitable for users intending to do faster cutting with lesser precision.
2.2 Crosscut Blades
Another popular table saw blade is the crosscut blades. The crosscut blades are popular for cutting across the grain. A key advantage of this blade is that they give off lesser waste materials after cutting.
Crosscut Saw Blade
Cross-Cutting blades have teeth numbers in the 80 to 90 range. A 90-teeth configuration makes the crosscut blade cut slower but smoother than the ripping blade.
2.3 Combination Blades
The combination blades are diverse in their applications as they have the ability to rip-cut and crosscut. Their unique quality of carrying out both rip-cut and crosscut makes them more popular among table saw users. Most people refer to them as a general cutting blade because of their peculiar feature of rip cutting and crosscutting.
Combination Saw Blade
Combination blades mostly come with a 40-50 teeth configuration, with medium-sized gullets. The teeth number and gullet size enable the combination blade to be able to execute both cuts well.
2.4 Composite Blades
This blade type is popular for its specialized functionality of cutting materials other than lumber. They are effective for cutting plywood and other special materials. Combination blades come in different types and materials. Each type possesses specific attributes that make it suitable for cutting select materials.
All of these blades have their functions and advantages. To know more, you can read about how to choose the right saw blade.

Section 3: How to change the table saw blade?
3.1 Working Method of the Sawblade.
The table saw has three major parts, namely;
- Electric Motor
- Table saw blade
The electric motor sits just below the table surface and spins the blade in the clockwise or anticlockwise direction. This statement implies that the electric motor converts electric power from the source to rotation on the blade.
The table saw blade must be turning towards you at all times. This turn must be such that you are feeding in the opposite direction. In essence, to ensure effective cutting, you must be feeding the workpiece against rotation direction.
Most users carry out two types of cutting on the table saw, namely rip cuts and crosscuts. The rip cut particularly cuts that are along the grain of the workpiece. This type of cut aims to reduce the workpiece length while maintaining the original width. In contrast, crosscuts are cuts across the grain. As a rule of thumb, this type of cut reduces the workpiece’s width and maintains its length.
All other operations on the table saw are deviations or different manipulations of these types of cut. Users only have to manipulate the blade angles or height to achieve different outcomes of cuts.
3.2 How to use a Sawblade?
The table saw is a tool most woodworkers must own. Using the table saw is relatively easy. Below is a step by step guide on using the table saw;

Section 5: How High Should I Set My Sawblade?
In recent years a debate has been going on to define the height to put your blade best properly. Below are three assertions to that intent:
5.1 The Safest Cutting Height
As a rule of thumb, the overall dependable guideline is that the teeth’ blade should be 1/8″ over the workpiece. You should know that the reason for this blade guideline is simple. These contributors claim a lesser probability of fatalities during accidents with the blade at this height.
5.2 Manufacturer’s Recommended Height
Manufacturers propose that you are safe if you have 3-5 teeth (ripping) and 5-7 teeth (crosscuts) in the workpiece.
The suggestion by the blade manufacturers is very similar to that of the claim for a safe height. They both are trying to minimize the extent of fatality in the event of a blade accident.
5.3 Higher Heights
As for the claim of having the blade at higher heights, there are some advantages. This suggestion proves that blades at higher heights will perform more effectively. Blades at higher heights put a lesser strain on the motor of the table saws and lesser heat generation.
Another claim is that at higher blade height, cutting is neater and better. Higher blades are of higher precision and better finishing. This assertion of blades surely places the table saw performance over fatalities in accidents.
