What is a circular saw blade?
A circular saw blade is around and flat blade consisting of teeth. Fitted to a circular saw, it can cut through various materials using a spinning motion.
A circular saw blade is versatile. It can be used on other power tools like miter saws, table saws, radial saws, and cut-off saws.
But not all circular saw blades are created the same. Others are simply designed for chopping wood while others are powerful enough to cut through aluminum, plastic, and metals.
What are the types of circular saw blade?
There are various types of circular saw blades, each designed to cut different materials. These include:
- Framing – one of the most common types of blade, it typically has 18 to 24 teeth. This is the type of blade you’ll need if you desire clean and precise cuts on wood.
- Finishing – compared to framing blades, finishing blades have more teeth. The teeth can range from 30 to 70 or even more. This is the type of blade best for cutting baseboards and hardwood flooring.
- Metal cutting – as the name suggests, this type of blade is designed to cut through various metals such as aluminum, metal sheet, and steel.
Which of those types of blade do you use to cut aluminum?
A metal cutting blade, which comes in various sizes and materials like carbide and steel, can cut through aluminum. It can also be used in cutting other materials like vinyl, hardwood, softwood, and plexiglass.
What are the things to consider in buying a circular saw blade for cutting aluminum?
- Blade diameter
- Number and material of teeth
- Material to be cut
- Bore size
Why is the blade diameter critical?
The blade diameter is critical because one, it determines the depth of cut, and two, the speed of the saw, which is expressed in rotation per minute (rpm).
The blade diameter would depend on the saw with which it will be paired with. Most circular saws can accommodate a 7 and 1/8-inch diameter blade. This can give a cutting depth of 2.25 inches. Table and miter saws, on the other hand, require blades with 10 to 12-inch diameter.
How important is the number of teeth?
The rule of thumb is simple: the more teeth that a blade has, the better it is at making precise cuts. It is for this reason that blades with more teeth are best used for cutting aluminum. Laminate finished with aluminum oxide, for instance, is more likely to chip if it is cut with a blade with few teeth. The blade will also dull faster due to the material it was used against.
On the other hand, circular saw blade with few teeth may be able to cut through aluminum faster than one with more teeth. However, you may be sacrificing the quality of the cut as the blade would likely remove more material.
How about the teeth material?
The teeth material will determine how effective or efficient the blade is in cutting through an item. The rule of thumb is that the material of the teeth or blade should be much stronger than the material you want to cut.
What are the materials used in saw blades?
As you may have learned after reading the reviews above, carbide is a popular material integrated into circular saw blades. It is a hard material compound that resists wear and temperature differences. It is highly durable and unalterable. This non-corrosive material is also resistant to friction.
It is common for carbide to be integrated with another hard material like tungsten, resulting in a super metal alloy. Tungsten carbide blades are known for their clean and precise cuts of aluminum and other non-ferrous metals.
There are also blades made of diamond, which is one of the hardest materials on earth. Those blades are used for cutting asphalt, concrete, and other abrasive materials.
How to choose a blade for your saw?
Aside from the features of the blade, you must also consider the specifications of your saw. The capability of your saw should be compatible with the blade diameter and type.
If you have a tile saw, you should look for blades that are 7 to 10 inches in diameter. Compound miter saws and table saws generally use blades that are 10 to 12 inches in diameter. These are also carbide-tipped.
You should also check the size of the hole in the middle of the blade, or the arbor hole. It should fit the shaft of your saw. Finally, take note of the RPM rating of the blade and ensure that it is compatible with the saw you intend to use it with.
What is kerf?
Kerf refers to the thickness of the blade. Circular saws are capable of accommodating blades of various thicknesses. For cutting aluminum, it is better to opt for a thinner blade as it is usually sharper. It can move quicker and remove less material with each cut.
What is arbor?
This is the shaft or spindle where the blade is mounted to. It can come in various sizes depending on the style and size of the saw. The most common arbor hole size is 5/8-inches for blades sized from 7-1/4 inches to 10 inches. As a general rule, the larger the diameter of the saw blade, the larger the arbor hole size is.
Can a wood blade cut aluminum?
Yes, it is possible to cut aluminum using a wood saw if it has carbide-tipped blades. Wood saw with fine-teeth blade can cut through aluminum with a thickness of not more than a quarter of an inch.
Can a hacksaw cut aluminum?
A hacksaw is a tool that’s commonly used for cutting various materials around the house. You may be surprised to learn that it is also capable of cutting aluminum and other soft metals. If you have a hacksaw at home, you can use a blade with 32 teeth to be able to cut soft metals like aluminum.
How many teeth does it take to cut aluminum?
This would depend on the blade material and the type of saw to be used. As mentioned earlier, a hacksaw with 32 teeth should be able to cut aluminum, although not at the fastest pace.
The DEWALT DW9152 circular saw blade is one proof that a circular blade does not need a lot of teeth to be able to cut through aluminum. Made of carbide, it has enough power to slice through aluminum.
Can you cut aluminum with a carbide saw blade?
Yes, definitely! A saw with carbide-tipped blades will have an easy time slicing through non-ferrous metals such as aluminum, brass, copper, and lead. Durability is another advantage of carbide saw blades as these can last longer than regular steel ones.
What is a kickback?
This is one of the most common and dreaded accidents that can happen while using a circular saw. It occurs when the blade binds on the material and either throws the material or saw itself back at the operator.
Kickback may also occur when cutting aluminum as the cut-off pieces are thrown off by the circular saw. This makes wearing of protective clothing important when cutting aluminum and other soft metals.
How do I know that a blade needs to be replaced?
Replacing or changing a circular saw blade is important because a dull blade will not be able to cut through the aluminum efficiently or quickly as you want.
A dull blade is easy to spot. If you push the circular saw blade through the aluminum and it doesn’t go as smoothly as you want, then it is likely because of the blade.
How to take care of the circular saw blade?
Regardless of the blade you choose, it is essential to take good care of it so that you can make your projects safely and efficiently.
One of the best ways to protect a circular saw blade is to clean it regularly. The blade is prone to contamination with pieces of dirt, dust, and sap clinging to it. These can add more friction if not removed, making it likely for the blade to overheat during usage. Moreover, dirty blades tend to dull quicker. You can use a brass-bristled brush or plastic cleaners in cleaning circular saw blades.
Aside from regularly cleaning saw blades, you should periodically sharpen it. The teeth should also be protected from chipping. This can be accomplished by avoiding contact with the teeth while the blade is in storage.
Best Circular Saw Blade for Cutting Aluminum – Conclusion
The use of a power tool is perhaps the most cost-effective way of cutting aluminum. Circular saws are not only relatively cheap but easy to use for a typical DIYer. But there are other more advanced ways of cutting the soft metal like the use of lasers, which can cut light to medium aluminum gauges. However, it can be costly, aside from the challenge of dissipating the heat.
