Circular saws cut on the upward stroke, which means that they rotate in a clockwise fashion, cutting from the bottom up. This is why when you’re using a circular saw, the side of the wood that will be your “good” side should be facing down.
When I first started using circular saws, what I knew about the circular saw blades was this: how many teeth the blade has and the size of the blade. Back in the spring, I had the opportunity to peer over the shoulder of a demo guy at a Diablo circular saw blades booth at a Home Depot event and was mind-blown at how he was slicing through thick metal like the circular saw blade was a hot knife through butter. Before jumping into which way to insert a circular saw blade when changing the blade, let’s first talk about which direction the blade of the saw actually cuts.
Most of us have been there at some pointstaring at a blade in one hand and a saw in the other wondering what the correct circular saw blade direction is. Getting the circular saw blade teeth going the correct direction is what’s at the heart of the matter. The saw’s motor runs the blade rotation in a way that the circular saw teeth direction points up as it enters the wood you’re cutting.
A circular saw blade spins upwards as it forces the wood to be held between the blade and the base of the circular saw. The teeth on your circular saw blade should point in an upward direction at the front of the saw. All circular saw blades spin in an upward direction with the teeth pointing up towards the base of the saw.
In layman’s term, the teeth of a circular blade should face such a direction so that the tips of the blade dig into the wood. Almost all circular saw blade would have arrow marked which would tell you the direction the blade should rotate. The blade of a circular saw should be fixed so that its teeth face the direction of spin.
To avoid this, clean your circular saw blade frequently, especially when not in use! By default, the blade of this kind of saw rotates in an anti-clockwise direction. On average, it costs between twelve and eighteen dollars for a seven-and-a-quarter-inch circular saw blade.
which way does a circular saw spin Related Question:
Which way is a circular saw supposed to spin?
This means that the circular saw cuts wood on the upstroke. For a right handed circular saw (most common), this means that the blade rotates counterclockwise, which is similar to the table saw. For a left handed circular saw, the blade rotates clockwise. Align the arrows on your blade to determine their rotation.
Which way do circular saws cut?
When appearance matters, make cuts with the good side facing down, as circular saws can splinter the wood on the top side. Making your cut line on masking tape can reduce splintering.
What happens if you put a circular saw blade on backwards?
You can run a saw blade backwards and it cuts pretty well. However it is not at all a good idea. The two big reasons not to do this is that saw tips are much more likely to come off if the saw blade is run backwards and that the whole saw blade is much more likely to come apart if it is run backwards.
Can you put a circular saw blade on backwards?
When cutting vinyl siding with a circular saw, install a fine-toothed blade backwards on the saw for a smoother, cleaner cut, especially in cold weather (when the material is brittle).
Is there a left and right handed circular saw?
Here’s a hint—it’s not by accident that manufacturers don’t call these “right-handed” and “left-handed” saws. Our Pros will tell you that it’s all about what you get used to and are comfortable with. In fact, most have both types of saws for different applications.
Why are so many circular saws left-handed?
The placement of the cordless saw blade, on the left side, gives you a clearer line of sight when you cut. The reason for this is because the main bulk of your circular saw is not blocking your view. Cordless circular left-handed saws provide you better movability.
Does Dewalt make a left-handed circular saw?
1. Dewalt Left Handed Circular Saw. Dewalt left-handed circular saw, corded, has a powerful 460 MWO, 5,150 RPM motor that provides more than enough power and speed to make difficult cuts without a problem. The material of the base plate is Magnesium which makes it strong and lightweight.
How do you cut straight with a circular saw without a guide?
To ensure a straight cut, press the saw firmly against the straightedge as you push it along. Clamp a perfectly straight board or metal straightedge to a sheet of plywood to make cabinet-quality straight cuts.
Why is my circular saw burning the wood?
Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty. If wood pitch resins build up behind the teeth of the blade, the cutting speed will slow down, increasing the chances for burns. Commercial blade cleaners are sold for this purpose.
Why is it called a worm drive saw?
What is a Worm drive saw? A worm drive saw has the motor attached at the rear. This is very powerful and its power is driven through two gears each set at 90 degrees. This setting implies that the engine produces more torque but less Rotation Per Minute (RPM) of about 4,500.
Are worm drive saws better?
Advantages of a Worm Drive Circular Saw The longer distance between the handle and the blade extends your reach while making a cut, which is helpful for crosscutting sheet goods. A worm drive also has larger gear teeth with more load-carrying capacity than a direct drive, which provides more power but also adds weight.
What is a worm drive saw?
Worm drive saws have the motor at the rear of the power tool, with gears oriented at 45° angles. The blade speed is slower but the torque is improved. A heavier and longer saw, a wormdrive model will usually have the blade on the left side. Worm Drive Circular Saws Torque Durability.
