A circular saw is an excellent tool and just about the most common tools in the workshop. It was invented in England back in 1780. The circular saw is also known as a buzz saw or commonly referred to as Hvac machine, despite the fact that Skil can be a manufacturer which makes circular saws. Together with the right blade, a circular saw can do cutting wood, steel, masonry and ceramic tile. Circular saws may be found in various sizes including 3″ to 16″. The most frequent corded dimension is 7 1/4″ and cordless is 5 3/8″ & 6 1/2″. The two main forms of circular saws: IN-Line Saws and Worm Drive Saws.
In-Line Saw – These represent the most popular forms of circular saws and are generally the least expensive. Moreover, they don’t weigh as much as the Worm Drive saws. An In-line saw’s motor sits perpendicular to the blade and a shaft runs right from the motor to operate a vehicle the blade. An In-Line saw will suit most of your applications, and apart from changing the blades, these are maintenance free.
Worm Drive Saw – A worm drive is for high quality use and has a tendency to cost a little bit more than the In-Line saws. A worm drive motor is positioned parallel with the blade and uses a gear to enhance the torque moved to the blade. These tend to be a bit heavier compared to in-line models. Also, worm saws are certainly not maintenance free, you will have to occasionally give a special oil to the motor, that is simply unscrewing a screw and adding the oil, it is quite easy.
Electric Brakes – This can be one feature I might get, no questions asked. An electric powered brake stops the motor in approximately two seconds after releasing the trigger, while Hvac machine with no electric brake is going to take about ten to fifteen seconds to avoid. The electric brake operates by reversing the flow of electricity towards the saw motor. The reason to go with the electric brake, which most models now offer, is to save limbs and fingers. After you are cutting for a while your arm will 90deyypky to get tired, so you want to make sure your safe all the time. Stopping the blade quicker means less chances of getting hurt.
Blade Capacity – As noted above circular saws may be found in different blade sizes. Should you be investing in a corded model I would choose a 7 1/4″ and for cordless, choose a 6 1/2″. The larger blade models are heavier, but in the end you should make less cuts, especially on angle cuts.
Shaft Locks – Be sure your saw features a lock. A Shaft lock is usually a button you press that holds the blade still, making changing the blade easier. When your buying Cutting blade, it will have this feature. The cheaper models usually do not possess this feature.
