Which way does a circular saw cut?

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.

Why do circular saws cut upwards?

The teeth of circular saw blades are intended to cut upwards into the material from below and this is for safety purposes. It is important that you should not spin them in a different direction just like you spin a table saw blade.

Which way should circular saw spin?

For blade-right models, the correct circular saw blade direction is usually with the label side out. For saws that have the blade on the left, it typically installs with the “ugly” side out. It’s not a hard, fast rule, though. You should always double-check.

Can you use a circular saw vertically?

Circular Saw It can be tricky to use in some situations, but the cuts tend to be straighter and more accurate than with almost any other portable saw. That makes it well-suited for trimming a single layer vertically.

Can you put a circular saw blade on backwards?

Yes – a circular saw blade can be accidentally mounted on the saw backwards – but it is a mistake you will only make one time because you will find out the instant you try to cut a piece of wood. It will not cut and you will be embarrassed at your mistake.

What happens if you put a circular saw blade on backwards?

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.

Can you cut sideways with a circular saw?

All circular saws can be adjusted to make angled bevel cuts up to at least 45 degrees. However, when the base plate is tilted all the way over, the lower blade guard has a tendency to catch on the edge of the board. If this happens, don’t force the saw.

Why wont my circular saw cut straight?

If you are unable to cut straight using your circular saw, you first need to check the positioning of the workpiece. The problem could simply be that the workpiece in unstable and needs clamping. You also need to check whether you are holding the blade properly and whether you have set the right cutting depth.

How do you use a circular saw to cut wood?

As a circular saw blade cuts up through wood, the fibers on top splinter off, a condition known as tear-out (usually worse on cross-cutting). If appearances are important, put the good side down when cutting. If you must cut the board face-up or if both sides will show, score the cut line with a utility knife before cutting.

Why is the bottom side of a circular saw blade clean?

Because a circular-saw blade cuts on an upward rotation, the bottom face, in which the teeth enter the cut, will almost always have a clean, tear-out-free surface. Meanwhile, the top face suffers tear-out so bad it cannot be used in a visible area on a project.

What happens when you cut a piece of wood with a saw?

As a circular saw blade cuts up through wood, the fibers on top splinter off, a condition known as tear-out (usually worse on cross-cutting). If appearances are important, put the good side down when cutting.

What determines the length of a circular saw cut?

The cleat location determines the length of the cut, and the fence guides your saw for perfectly square cuts every time. Circular saws usually splinter the wood that’s facing up and cut cleanly on the side that’s facing down.
