A circular saw is a great tool and one of the more common tools in the workshop. It absolutely was invented in England in 1780. The circular saw is also called a buzz saw or commonly known as the cutting blade, although Skil is really a manufacturer which makes circular saws. Using the right blade, a circular saw is capable of cutting wood, steel, masonry and ceramic tile. Circular saws come in various sizes ranging from 3″ to 16″. The most typical corded size is 7 1/4″ and cordless is 5 3/8″ & 6 1/2″. There are 2 kinds of circular saws: IN-Line Saws and Worm Drive Saws.
In-Line Saw – These are the most typical kinds of circular saws and are generally the least expensive. In addition, they don’t weigh around 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 the blade. An In-Line saw will suit most of your applications, and except for changing the blades, these are maintenance free.
Worm Drive Saw – A worm drive is made for heavy-duty use and will cost a little more than the In-Line saws. A worm drive motor is positioned parallel with the blade and utilizes a gear to improve the torque transferred to the blade. These are generally a little bit heavier compared to in-line models. Also, worm saws will not be maintenance free, you will need to occasionally add a special oil to the motor, which can be nothing but unscrewing a screw and adding the oil, it is quite easy.
Electric Brakes – This can be one of the things I would get, no questions asked. An electrical brake stops the motor in about two seconds after releasing the trigger, while Duct machine with no electric brake will take about 10 to 15 seconds to prevent. The electrical brake works by reversing the flow of electricity towards the saw motor. The reason to complement the electric brake, which most models now offer, would be to save limbs and fingers. After you are cutting for a time your arm will 90deyypky to have tired, so you want to ensure your safe constantly. Stopping the blade quicker means less chances of getting hurt.
Blade Capacity – As noted above circular saws come in different blade sizes. Should you be buying a corded model I would personally go along with a 7 1/4″ and then for cordless, go along with a 6 1/2″. The bigger blade models are heavier, but over time you will need to make less cuts, especially on angle cuts.
Shaft Locks – Be sure your saw carries a lock. A Shaft lock is generally a button you press that holds the blade still, making changing the blade easier. When your buying circular saw blades, it ought to have this feature. The cheaper models usually do not possess this feature.
