The teeth bevel in alternating and opposite directions (left/right). This creates a clean cut with the quality of the cut increasing along with the angle. These blades typically have a mid-range tooth count and make excellent all-purpose blades for both rip and crosscuts.
So we’ve summoned all of our wisdom and powers of brevity to bring you this useful guide to choosing the right circular saw blade. Choosing the right circular saw blade for rip cuts might be even more important. We hope this article about choosing the right circular saw blade cuts through the confusion so you can select the best accessory for the job.
A circular saw is an electric saw that turns a round flat blade to cut wood, metal, or plastic depending on the blade selected. The most common types include circular saws, saber saws, and reciprocal saws. Saber Saw: A saber saw features a small saw blade that moves up and down across the object to be cut.
Be extremely careful when using a circular saw and wear proper eye, ear, and lung protection regardless of the blade that is installed. The better approach is to use a jig saw with a fine blade, or a table saw with an 80-tooth blade. Straight cuts with a circular saw and fine blade can work, especially if the panel and a straight edge guide board are clamped in place.
how circular saw blade works Related Question:
How does the blade on 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.
How does the circular saw work?
A circular saw is an electric saw that turns a round flat blade to cut wood, metal, or plastic depending on the blade selected. Circular saws have a handle with on/off trigger switch, an arbor nut to hold the blade in place, and guards to protect the operator from touching the spinning blade.
How does a saw blade work?
To get these lines, the teeth are bent outwards from the blade, each tooth in the opposite direction to the one next to it. The cut in the wood is wider than the saw blade which prevents the saw from getting stuck as you cut and also allows you to make adjustments if you are going slightly off line.
How does a circular saw blade spin?
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. It’s intentional to create the most stable, accurate, and safe cutting. As the blade teeth hit the material, they rip from the bottom through the top.
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.
Can I put a metal cutting blade on my circular saw?
Only blades and discs specified for cutting metal should be used. These professional circular saw blades are perfect for cutting through aluminium, copper, lead and other non-ferrous metals; while these diamond cutting discs will make light work of cutting through stainless steel.
How do you use a circular saw without a table?
Fit your circular saw with an edge guide. Set the depth of the blade accurately enough for it to go through the wood and not cut under the surface. Place the guide on base of the circular saw lines and markings you made earlier on the wood. Ensure that the saw is free to move, and the power cord is not entangled.
Why is my circular saw kicking back?
Overheating a saw blade can cause it to warp and result in a kickback. Buildup of sap on the blades, insufficient set, dullness and unguided cuts, can all cause an overheated blade and kickback. Never set a blade deeper than is required to cut the work piece 1/8 in. to 1/4 in.
How many teeth should my circular saw blade have?
Number of Teeth Generally, blades with more teeth will provide a smoother, finer cut whereas blades with fewer teeth will provide a rougher cut. The benefit of fewer teeth is faster cutting and a lower price. For most construction work, a 24-tooth general use blade is sufficient.
How many teeth should a circular saw plywood blade have?
Framing blades have 24 teeth and are effective for jobs such as rough carpentry, where speed is more important than getting a clean cut. Plywood blades have 100 or more fine teeth designed to create a finish with minimal splintering.
Is more teeth on a saw blade better?
Blades with more teeth yield a smoother cut. Blades with fewer teeth remove material faster, but tend to produce a rougher cut with more “tearout”. More teeth means you will need to use a slower feed rate.
How do I know when to change my circular saw blade?
Look for worn-down, chipped, broken and missing teeth or chipped carbide tips that indicate it’s time to replace a circular saw blade. Check the wear line of carbide edges using a bright light and magnifying glass to determine if it’s beginning to dull.
Why do circular saws cut up instead of down?
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.
How long should a circular saw blade last?
They can last between 12 and 120 hours of continuous use, depending on the quality of the blade and material they’re used to cut.
Why is my circular saw motor smoking?
A longer instant of cutting, dampness of wooden piece, a dull blade and user errors are key factors that can cause a circular saw to smoke for some time. Excluding motor burn out, as if it has happened to your motor, it is quite certain that your motor needs to be repaired.
