Regular circular saws have an RPM of 6,000 or higher while worm drive saws have an RPM of not more than 4,500.
Regular circular saws or sidewinders, on the other hand, are more portable than worm drive saws even though they also provide the same performance as worm drive saws. Many professionals who have both saws, prefer using a regular circular saw for cross-cutting and worm drive saw for ripping. In case you are beginning, both the worm drive saw and regular circular saw will be ideal for you.
“Rotation speed of a circular saw should follow the manufacturer’s recommendations for the specific saw blade. All saw blades are designed for safe use at a maximum number of Revolutions per Minute or RPM”, representing the number of turns in a minute. Saw blades with small diameters can be mounted on saws with more than 10,000 RPM, although it’s the upper limit for regular blades. Not every circular saw blade is recommended for high RPMs. Blade has limitations when rotation speed comes around, this limit is closely linked to its diameter.
For extended blade life and quality of cut, saw blades should run between 10,000 and 18,000 SFPM. Never exceed 18,000 SFPM! To calculate SFPM: Multiply the diameter of the blade times Pi to get the circumference, then multiply circumference by RPM to get inches per minute and divide the inches per minute calculation by 12 to get the feet per minute. Best results on most materials would be about 15,000 SFPM..
In general, harder materials and blades with a thicker rim require slower speeds, while softer materials and blades with thin rims permit faster speeds. There is a relationship between the diameter of the blade or bit circle, the rotational speed of the blade or bit and the linear speed of its teeth. Maximum RPM. Maximum RPM often listed on saw blades refers to the maximum safe rotational speed for a given blade – not optimum cutting speeds.
Thanks Jim for focusing me on that aspect of my table saw along with the fact that I really should be looking at saw tooth tip speed and RPMthanks Jim. Steve NeulI have decided to put the 7-1/4″ blade back on the circular saw for which it was intended and purchase a new 10″ fine tooth blade for cutting thin plywood and veneer on the Unisaw. Tool Agnosticthanks for pointing out the possible consequences of exceeding the safe rotational rate of a saw bladeand for bolstering my confidence with respect to the “Safe use” of a smaller diameter blade on a 10″ table saw.
how fast does a circular saw spin Related Question:
How fast does a circular saw blade spin?
There is in fact fairly common agreement that for general work, the tooth should be moving somewhere around 130 to 170 feet per second. That may look like a big spread for you, but if you look at the fact that we are dealing with tools that vary from 3,000 RPM to 50,000 RPM, 130 – 170 fps is rather consistent.
How fast does a miter saw spin?
What is a 10″ Miter Saw? A 10″ miter saw is named after the size of its blade at 10 inches. You will find that many 10-inchers spin at a speed of 5000 rpm, or revolutions per minute. They work with an amperage capacity of between 12 – 15 amps.
What is a good RPM for a table saw?
Table saws typically run at 3,000 to 4,000 RPM, which stands for revolutions per minute. A table saw in good condition runs at 3,450 RPM. You can alter the table saw blade RPM by increasing or decreasing the arbor pulley’s size.
Which way should a circular saw spin?
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.
What is the difference between a chop saw and a circular saw?
A miter saw can do most of the same tasks as a circular saw, but both tools have their strengths and weaknesses. A miter saw is stationary and the blade is pulled downward onto the wood, while a circular saw is handheld and the blade is pushed through the wood.
How fast is a table saw blade?
Ellis Walentine: Most table saws run in the 3,000 to 4,000 rpm range. You could decrease your blade rpm to 4,140 by increasing the size of the arbor pulley to 2 1/2″.
Can chop saws cut angles?
Types of Cuts A chop saw can cut one angle, a 90-degree angle. Chop saws are good for making excellent and quick straight cuts. If you want to do something more detailed or at an angle, a chop saw is not the best choice.
How many mph is 3000rpm?
So, 3000 rpm would be about 26 mph. As a rough approximation, add 2 zeroes to the mph to get rpm: 93 mph is about 9300 rpm.
How much power does a table saw need?
The typical table saw in a hobbyist woodworker’s shop is about 2 hp and will need about 1,725 watts to run smoothly. Running smoothly also has to do with how you attempt to use it. A 2 hp motor in your table saw can handle cutting a 2” thickness, but the motor will be taxed too much to cut something larger.
Why does my circular saw spin clockwise?
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.
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.
Why do circular saws cut upwards?
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.
Can I use a jigsaw instead of a circular saw?
Although a jigsaw can be used for most of the tasks that a circular saw can perform, including straight cuts and cuts on a tilt, the jigsaw uses that really take advantage of the tool’s qualities are jobs such as kitchen fitting and joinery, with their frequent need for complex cuts.
How much does a miter saw cost?
A basic compound miter saw starts at $100, while miter saws with sliding blades start at $125. Dual-bevel miter saws start at $200, and professional-level miter saws with special features can cost as much as $800.
What should you do if the blade binds in a cut?
Do not remove the circular saw from the cut when the blade is still rotating. Release the switch immediately the saw stalls or binds. Always hold the circular saw with both your hands to increase grip power. You should guide the large stock to avoid pinching on the blade.
