A circular saw is a great tool and probably the most common tools within the workshop. It was actually invented in England in 1780. The circular saw is often known as a buzz saw or commonly called the cutting blade, though Skil is really a manufacturer that creates circular saws. Using the right blade, a circular saw can do cutting wood, steel, masonry and ceramic tile. Circular saws can be found in different sizes ranging from 3″ to 16″. The most frequent corded size is 7 1/4″ and cordless is 5 3/8″ & 6 1/2″. There are two kinds of circular saws: IN-Line Saws and Worm Drive Saws.
In-Line Saw – These are the basic most common varieties of circular saws and are typically the most affordable. Moreover, they don’t weigh up to the Worm Drive saws. An In-line saw’s motor sits perpendicular for the blade along with a shaft runs directly from the motor to operate a vehicle the blade. An In-Line saw will suit most of your applications, and except for changing the blades, they may be maintenance free.
Worm Drive Saw – A worm drive is designed for heavy duty use and has a tendency to cost a little more in comparison to the In-Line saws. A worm drive motor is positioned parallel together with the blade and relies on a gear to improve the torque transferred to the blade. These are generally a bit heavier compared to in-line models. Also, worm saws are not maintenance free, you need to occasionally give a special oil on the motor, which happens to be merely unscrewing a screw and adding the oil, it is rather easy.
Electric Brakes – This can be one of the things I might get, no questions asked. An electrical brake stops the motor in about two seconds after releasing the trigger, while Duct machine without having an electric brake will require about 10 to 15 seconds to stop. The electrical brake operates by reversing the flow of electricity to the saw motor. The reason why to go with the electric brake, which most models now offer, is always to save limbs and fingers. Once you are cutting for a while your arm will 90deyypky to acquire tired, so you want to make certain your safe all the time. Stopping the blade quicker means less probability of getting hurt.
Blade Capacity – As noted above circular saws can be found in different blade sizes. When you are investing in a corded model I would go along with a 7 1/4″ as well as for cordless, go with a 6 1/2″. The bigger blade models are heavier, but in the long term you should make less cuts, especially on angle cuts.
Shaft Locks – Ensure your saw features a lock. A Shaft lock is usually a button you press that holds the blade still, making changing the blade easier. Should your buying circular saw blades, it must have this feature. The cheaper models usually do not have this feature.
A saw blade is one of the most important parts to some circular saw. Not simply having the right blade is very important, but in addition having a sharp blade is very important. There are several blades for various jobs and below we cover the common uses. If you would like a much more detailed explanation on saw blades please follow this link – Blades.
