The miter saw is one of the most used cutting tools in woodworking. When using a miter saw, its power consumption is a major factor. Miter saws are powered by electricity. According to the performance, its electricity consumption can be varied. So let’s see how much power, volts, and amps need for the miter saw and what are power factors we must consider when we select a miter saw.
Normally, miter saw power consumption depends on the types of the miter saw and its performance. A Single-bevel miter saw will consume 1200 W, a dual-bevel miter saw will consume 3300 W of electric power, and a cordless miter saw will consume 180W of power.
Miter saws are mainly corded and cordless. Cordless miter saws have limited capacity usage due to their battery. But corded miter saws can use a wide range. More than that, there are both advantages and disadvantages considering the power consumption of the miter saw. So let’s see more details about miter saws’ power consumption step by step.
What is Watt in Miter Saw?
The Watt (W) in the miter saw is the power of the miter saw. The Watts of the miter saw is the multiplication of voltage and current. The average power consumption of the miter saw is between 1200 and 3300 Watts. The corded miter saws produce more power than the cordless miter saws. The cordless miter saw Watts are calculated by the manufacturer, while cordless miter saw watts can be calculated by the battery voltage (V) and capacity (Ah).
The miter saw power can be converted to noise, heat, spark, and friction. The percentage of power input to power output is the efficiency of the miter saw.
How Many Amps Does a Miter Saw Use?
Normally, Amps requirements for the miter saw depend on the type of the miter saw. According to that corded 10-inch miter saw will need 10 Amps, and a 12-inch miter saw will need 15 Amps. The cordless miter saw will need a 3-5 Amh battery as the power solution.
A miter saw will use more amps (or higher electrical current) when it is cutting through dense or hard materials like hardwood or metal. This is because the saw needs more power to drive the blade through these materials. The amps will also increase if the blade is dull or damaged, causing the motor to work harder.
On the other hand, the miter saw will use fewer amps when it’s idle or when cutting through softer materials like pine or plastic. In these situations, the saw doesn’t require as much power to operate efficiently.
The 4 factors that affect the amps of a miter saw are:
- The hardness and thickness of the material being cut
- The sharpness of the blade
- The efficiency of the motor
- The rated power of the motor
How to Use Miter Saw Power Efficiently?
When we use a miter saw, we must know how to use its power in an efficient way. It can be wasted due to noise, friction, spark, and motion of the motor. When we need to use a miter saw efficiently, we have to pay attention to the saw blade, workpiece, and motor. So, let’s see how these things affect the efficiency of the miter saw.
Use A Proper Number of Saw Teeth with the Proper Saw Blade
The saw blade is used for cutting the workpiece. Mostly saw blades are available in 10 inches and 12 inches. The number of teeth is varied with the diameter of the saw blade. Normally, we can see a higher number of saw blades and a lower number of saw blades in every diameter. 24-60 teeth in 10-inch saw blade and 32-80 teeth in 12-inches saw blade.
Using the miter saw, we can cut crosscuts, rip cuts, bevel cuts, and miter cuts. We have to pay attention to the chip removal rate in the cutting process. If the blade has a lower number of teeth, it can remove the higher amount of chips. This is really good for the rip cuts.
When we crosscut, it is better to use a large number of teeth. The cross-section is stronger than along the grains. So it needs more strength to cut. As a result of this, saw blades need a higher number of teeth for fine crosscuts. When you use this, you can use a saw blade in an efficient way.
Use a Sliding Miter Saw Instead of a Regular Miter Saw
When using a regular miter saw, we have to lower the cutting head. Suddenly, the saw blade tends to cut a longer cutting path. It can require more power due to the high amount of teeth engagement. But a sliding miter saw can push and pull the saw head with a rotating blade. Few of the saw teeth will engage with the short-cutting path. As a result of this, it can quickly cut the path with high efficiency. So it can use a miter saw in an efficient way.
Use a Brushless Miter Saw
Miter saw motors are two types. Brushed and brushless are them. Brushed miter saws consume a lot of power due to their brushes and internal frictions. But brushless motors really use less power than brushed ones. Hence, you must use a brushless miter saw to reduce power consumption.
Switch off the Additional Power Usage
If you are using LED or laser miter saw, you have to supply the power for them. The battery powers both because they consume the least power.
Why is the Miter Saw Not Powered Up?
A miter saw can be not powered up due to the below 5 reasons such as,
- The power cord of the miter saw could be damaged or not properly plugged in.
- The fuse or circuit breaker for the outlet you’re using may have blown or tripped.
- The miter saw’s power switch may be faulty.
- The miter saw motor could be burnt out.
- The carbon brushes inside the miter saw motor may be worn out.
Can I Use a Power Generator to Run the Miter Saw?
Obviously, you can use a power generator to run the miter saw. If the power generator can produce more power than required by the miter saw will be the only condition. Imagine you have 120V with 10 amp miter saw that will require 1200W power. If you have a 4000W-5000W power generator, you can easily operate the miter saw.
How Many Volts Need for Miter Saw?
Normally, domestic-use miter saws need 120 V voltage, and 220V will be required for high-performance miter saws. Cordless miter saws will work with 24V, 36V, and 56V voltages with DC current.
How Much Power Does a Circular Saw Consume?
A circular saw consumes 2300W of power when it is starting. While it running it consumes 1400W of power. In cordless circular saws, It will be 30-180 watts of power will be consumed while running..
