How thick is a circular blade?
There is no definitive answer as to how thick a circular saw blade is because it largely depends on the blade being purchased and the desired finish. Kerf can be measured in inches, but for easy reference, anywhere between 1.5mm and 3mm is considered thin.
What is standard size circular saw?
7 1/4 inchesBlade Size The most common and useful size for DIYers is 7 1/4 inches. Saws this size will cut through material more than 3-inches thick, and they also offer the widest variety of blade choices for cutting substances other than wood.
What is the kerf of a saw blade?
One of the features to look for in a particular saw blade is the blade's kerf — or the width of the material that is removed when cutting. This is determined by the width of the blade's carbide teeth.
What is Arbor size on a circular saw?
The size of an arbor hole on a circular saw blade will vary depending on the blade's outside diameter. As the scale increases or decreases, the arbor hole generally follows suit. For standard 8″ and 10″ blades, arbor hole diameters typically sit at 5/8″.
Is a 6.5 or 7.25 circular saw better?
In short, a 6.5 circular saw is less powerful than a 7.25 circular saw. 7.25in saws have more torque and can generate more power. They also tend to be a bit bigger and heavier than their 6.5 counterparts.
Will a 6.5 inch circular saw cut a 2x4?
The 6.5 will cut up to 2 1/16”, while the 7 ¼” cuts up to 2 ⅜”. Minor sure, but it's when you tilt them into 45 degree angles, that the 7 ¼” can do something the 6.5 can't. Cut through a 2×4. Of course more capacity, typically means more weight.
What size circular saw Do I need to cut 2x4?
The circular saw is a portable power saw that uses a circular blade. You push the blade into the material as opposed to a table saw where you push the material into the blade. You can use the standard 5 ½″ circular saw to cut 2x4s.
Can a 6 1 2 circular saw cut a 4x4?
Like miter saws that measure less than 12 inches, a circular saw's 6.5-inch or 7.25-inch blade will not cut cleanly through a 4×4. The maximum depth of most circular saws is just 2.5 inches. This means you'll need to make two cuts. Having to make two cuts makes it easier to set up the cut.
What are high grade circular saw blades made of?
Extremely high grade circular saw blades are made from steel that wasn’t rolled at the steel mill. This steel is much more costly than regular sheet steel, due to the increased labor involved in handling it in processing.
How do carbide tipped circular saw blades work?
If you look at the construction of a carbide tipped circular saw blade, you will note that the blades teeth are welded onto the blade plate, and are thicker than it. In the case of high speed steel saw blades, the teeth are integral with the blade, although the kerf is still thicker than the thickness of the blade plate. This is caused by the teeth being “offset” from the blade. All that means is that they are bent slightly to the side, alternating sides from one tooth to the next. One more thing that can affect the saw kerf is the flatness of the blade. If you can imagine how a blade would look that is slightly warped. In that case, the teeth would not follow each other in the exact same line, but rather wobble back and forth a bit, much as a car tire that is mounted on a bent rim. This wobble would actually cause the blade to cut a wider kerf than the thickness of the teeth warrants.
Why Thin Kerf Blades?
So, with this risk from thinner kerf saw blades, why would any woodworker want to use them? The major reason for using thin kerf blades is to save materials. When one is working with exotic hardwoods, which can run as much as $60.00 per board foot, even 1/16” inch of wood is important to save. Every scrap is usable for something. Just multiply the thickness with the width and length of sheet and now look at the total amount of wood that’s saved. Next to the less material loss, benefits like competitive price, lightweight and possibility to mount them on every circular saw, no matter is it weaker or more powerful, make thin kerf saw blades a favorite choice among woodworkers.
How thick is a kerf saw blade?
Thin kerf blades will generally be 25% thinner, creating a cut of 0.091” or about 3/32”. The thinnest kerf circular saw blades currently made are 0.059” (about 1/16”) thick. This is especially helpful for making precise cuts on engineered lumber or plywood. These thinner blades cannot absorb impacts so well, and are more prone to bending ...
Why is my circular saw blade not flat?
Since sheet metal is often rolled at the mill where it is forged, then unrolled and cut into sheets, before fabrication, it may not be totally flat. While your eye probably cannot see the amount of curve in the blade, it can still cause the saw kerf to be greater than the thickness of the blade and teeth warrant. Extremely high grade circular saw blades are made from steel that wasn’t rolled at the steel mill. This steel is much more costly than regular sheet steel, due to the increased labor involved in handling it in processing. However, a blade made with this type of steel will have no wobble, making for the smoothest possible cut.
What is a kerf on a saw?
Saw blade “kerf” refers to the thickness of the slot which the saw blade will cut. It is often used as well to define the thickness of the blade itself, or at least the widest point on the blade, as this will define the width of cut made.
What does it mean when a saw blade is bent?
All that means is that they are bent slightly to the side, alternating sides from one tooth to the next. One more thing that can affect the saw kerf is the flatness of the blade. If you can imagine how a blade would look that is slightly warped.
How Thick Is a Circular Saw Blade?
The “kerf” is what defines the thickness of a circular saw blade. Thinner kerfs denote less thickness of the blade, and hence, sharper and more precise cuts, and vice-versa.
Why is it important to keep track of how long a circular saw is powered?
Therefore, it’s imperative to keep track of how long the circular saw is powered to avoid excessive heating and damage.
What are the two types of kerfs on circular saw blades?
Circular saw blades come with two general categories of kerfs- thin kerf and full kerf.
Why do kerf blades lose sharpness?
The dullness in their edges can lead to uneven or undesired cuts and ruin your project altogether.
Why do blades get warped?
The reason behind this phenomenon is that increased flatness causes the blade plate to become more warped. Consequently, the blade’s teeth are no longer aligned, but rather the perimeter of the blade becomes zig-zagged.
How many inches is a kerf?
For an entire kerf blade, the usual kerf is approximately 1.110 inches. On the other hand, the typical kerf for a thin kerf blade falls around 0.091 inches.
What are the benefits of wood saw blades?
The added benefits to such blades are minimal material wastage or sawdust (in wood) and low power consumption.
What type of blade is used to cut wood?
While this type of blade isn’t usually used to cut wood, it is needed enough in woodworking projects that we decided to include it. Plywood Blades. As the name suggests, these blades are designed to cut through plywood. Plywood can be a troublesome material to cut, which is why a particular type of blade is required.
Why do saw blades have smaller gullets?
Crosscutting blades have smaller gullets because they produce smaller chips. This type of blade tooth is designed for extra-fine crosscutting. This is how the sawtooth is angled in relation to the center of the blade.
What is a ripping blade?
Ripping Blade. This blade is made with very large teeth that allow it to cut parallel to the wood grain.
Why is a thicker blade better than a thinner blade?
The “kerf” of a blade is simply how wide it is. A thicker blade will last longer because you can resharpen it more; there is simply more material to work with. However, thinner blades are sharper and can cut faster. They are a particularly good choice for saws that don’t produce much power. But, they cut rougher edges than thicker blades.
What is a dado blade?
A dado blade is designed to cut dados, or grooves, into wooden materials . There are two main types of dado blades – stacked blades and wobble blades. Stacked blades consist of two saw blades and a chipper blade put together. The saw blades cut out the groove and the chipper removes the waste material and smooths the bottom. A wobble blade is simply a circular blade mounted onto an adjustable hub. This allows you to change the depth of the cut, though usually not very accurately.
Why use a thin kerf blade?
Thin kerf blades are, simply put, thin. This makes it possible to get more cuts out of a single piece of wood. For this reason, they are often used by pencil manufacturers and other companies who make small, wooden objects. These thinner blades can also allow an underpowered saw to work better since the available power is focused on a smaller area.
What is a wobble blade?
A wobble blade is simply a circular blade mounted onto an adjustable hub. This allows you to change the depth of the cut, though usually not very accurately. Fine-Tooth Finish Blades. These blades are designed for extra-smooth cuts.
What is a circular saw?
Your circular saw is solid tool, it is actually your best ally in the layout of your interior, and you have to take care of it all the time. However, it is nothing without a high quality blade. The saw blade will determine the quality of the cut, so the choice of a circular saw is very important. The selection of the saw blade depends on many criteria, such as the type of work that will be intended to be done or whether for frequent or occasional use.
When should I replace my circular saw blade?
Knowing when to change your circular saw or table saw blade is important to the project that you are working on. If you have a dull blade, you are not going to cut efficiently and quickly as you want.
What is the angle of attack on a saw?
The angle of attack is the inclination angle of the tooth tip. The angle of attack is positive when the tooth is bent forward and negative if it is tilted backwards. Negative angle blades are always used with radial or miter saws for cutting wood or metals. This inclination prevents the abrupt return of the blade to the user.
Why are construction blades used in carpentry?
They are also known as the construction blades, where the quality of the finish is not so important. Also, the large spaces between the teeth allow rapid evacuation of chips.
Why do circular blades have indentations?
Note that the indentations are provided so that the metal can expand under heat. Because the circular blades or any type of blades gets heated by the continuous operation.
How many teeth does a blade have?
There are blades with 10 to 80 teeth. A very important factor to take into account is how many teeth your blade has, because it directly influences the speed of the cut as well as its finesse. The more the teeth, the better the cutting finish will be, but also the slower the cutting process.
How to determine the depth of a cutting blade?
The necessary cutting depth is indicated by the diameter of the blade itself.
Where is the blade on a circular saw?
The majority of circular saws are sidewinders, so the blade is mounted on the right-hand side of the saw’s motor. If you’re right-handed, you will need to lean over the saw to be able to see the cut line.
What is a circular saw?
By its most simple definition, a circular saw is any power-saw that utilizes a toothed or abrasive disc/blade that is able to cut by using a rotary motion that spins around an arbor. The concept is simple in nature, but there are a lot of moving parts involved within.

How do electric brakes work on a saw?
Brakes: Electric brakes are used to reverse the flow of electricity in the saw’s motor whenever the trigger is released. Reversing the current stops the blade’s faster than just letting it spin on its own until the momentum stops. These brakes can usually stop the blade in as little as two seconds.
What is circular saw?
Circular saws have traditionally fallen into the two distinct yet similarly serpentine-sounding categories of sidewinder and worm drive. The categories generally differ in motor orientation and design, weight, torque, and RPMs. Perhaps most significantly, a worm drive saw was traditionally left-side blade and a sidewinder positioned itself ...
What is blade right on a sidewinder saw?
Blade-Right for the right-handed user presents a bit of a challenge as you have to look past your right shoulder to see the sight/cut line window, regardless of one- or two-handed operation. More or less all corded sidewinder saws operated with a blade-right configuration. Using the saw this way will place the motor weight over the waste edge when you cut from the end-side of a board or sheet. This means the saw eventually cuts off its own support. Most users have no trouble holding the saw steady, but this can result in bind-ups.
Which hand to hold worm drive saw?
Many tradesmen will hold or stabilize the material with the left hand while operating the saw with the right hand. However, for two-handed operation, grabbing the pommel handle with the left hand not only obscures the sight/cut line window, but it makes the left arm/wrist cross over the blade. Traditionally, all worm drive saws operated in ...
Can you flip a cross cut board?
Unless you go into contortions, the saw motor will be facing you, its weight over the very piece about to fall away from the sheet. With cross-cuts, you can flip directions and stand on the opposite side of the board. Not so much with a piece of plywood or OSB.
