The 165mm circular saw is a small to medium sized saw and it is one of the more popular sizes available. This saw excels at cleanly cutting wood up to a depth around 55mm, depending on the manufacturer. As well as being able to make relatively deep cuts, these machines are usually quite light and portable, therefore making them a good all-rounder. 

• The subsequent criteria needed for choosing a circular saw is the diameter of the blade to determine the depth of cut. The more popular diameters tend to be 190mm & 235mm. Circular saws with this 165mm diameter blade are broadly in the middle of the diameter blade range.

• Choosing your power source: The first choice is between a mains (110v or 240v) or a cordless tool. 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
• With regards to cordless (battery powered) tools there are a variety of chemical types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
