A circular saw is a superb tool and one of the most common tools from the workshop. It had been invented in England way back in 1780. The circular saw is also known as a buzz saw or commonly known as the Hvac machine, even though Skil is actually a manufacturer which enables circular saws. With all the right blade, a circular saw is capable of doing 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″. There are 2 varieties of circular saws: IN-Line Saws and Worm Drive Saws.
In-Line Saw – They are the most frequent types of circular saws and are usually the most affordable. Furthermore, they don’t weigh as much as the Worm Drive saws. An In-line saw’s motor sits perpendicular towards the blade as well as a shaft runs directly from the motor to operate a vehicle the blade. An In-Line saw will suit your main applications, and apart from changing the blades, they can be easy to maintain.
Worm Drive Saw – A worm drive is for heavy duty use and will cost a bit more than the In-Line saws. A worm drive motor is positioned parallel using the blade and utilizes 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 have got to occasionally give a special oil on the motor, which can be simply unscrewing a screw and adding the oil, it is very easy.
Electric Brakes – This really is one feature I would get, no questions asked. A power brake stops the motor in approximately two seconds after releasing the trigger, while Duct machine with no electric brake is going to take about 10 to 15 seconds to avoid. The electric brake operates by reversing the flow of electricity towards the saw motor. The reason why to select the electrical brake, which most models now offer, is usually to save limbs and fingers.

Blade Capacity – As noted above circular saws may be found in different blade sizes. If you are purchasing a corded model I would go along with a 7 1/4″ and also for cordless, choose a 6 1/2″. The larger blade models are heavier, but over time you will need to 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 supports the blade still, making changing the blade easier. If your buying Cutting blade, it must have this feature. The cheaper models usually do not have this feature.
