A circular saw is a good tool and probably the most common tools within the workshop. It was actually invented in England back in 1780. The circular saw is also known as a buzz saw or commonly called the cutting blade, though Skil is a manufacturer which enables circular saws. Together with the right blade, a circular saw can perform cutting wood, steel, masonry and ceramic tile. Circular saws can be found in various sizes ranging from 3″ to 16″. The most typical corded dimension is 7 1/4″ and cordless is 5 3/8″ & 6 1/2″. There are 2 varieties of circular saws: IN-Line Saws and Worm Drive Saws.
In-Line Saw – These are the most common forms of circular saws and are typically the most cost effective. Furthermore, they don’t weigh as much as the Worm Drive saws. An In-line saw’s motor sits perpendicular on the blade plus a shaft runs straight from the motor to drive the blade. An In-Line saw will suit most of your applications, and apart from changing the blades, they may be maintenance free.
Worm Drive Saw – A worm drive is designed for heavy-duty use and is likely to cost a tad bit more compared to the In-Line saws. A worm drive motor is positioned parallel with all the blade and works with a gear to increase the torque moved to the blade. These are usually a little bit heavier compared to in-line models. Also, worm saws are certainly not easy to maintain, you will need to occasionally give a special oil for the motor, which is nothing more than unscrewing a screw and adding the oil, it is quite easy.
Electric Brakes – This can be one of the things I might get, no questions asked. An electric powered brake stops the motor within two seconds after releasing the trigger, while Hvac machine without having an electric brake can take about ten or fifteen seconds to quit. The electric brake functions by reversing the flow of electricity for the saw motor. The reason why to go with the electrical brake, which most models now offer, is usually to save limbs and fingers. Once you are cutting for some time your arm will 90deyypky to get tired, so you want to be sure your safe always. Stopping the blade quicker means less probability of getting hurt.
Blade Capacity – As noted above circular saws can be found in different blade sizes. Should you be getting a corded model I might go with a 7 1/4″ and for cordless, go with a 6 1/2″. The greater blade models are heavier, but in the long term you will have to make less cuts, especially on angle cuts.
Shaft Locks – Ensure your saw includes a lock. A Shaft lock is generally a button you press that holds the blade still, making changing the blade easier. In case your buying Cutting blade, it will have this feature. The cheaper models usually do not have this feature.
A saw blade is probably the most significant parts to a circular saw. Not only getting the right blade is very important, but also having a sharp blade is vital.
