There is no one circular saw that is perfect for all renovators and woodworkers. However, there are a few things I have learned regarding circular saws that apply to the majority of the buyers out there. Here they are:
- Avoid Cordless – Battery-powered circular saws can get very pricey and simply do not have the power needed to quickly cut through many materials, so unless you plan to use the saw in the middle of the woods, go with a corded saw.
- Stay with Sidewinder – While worm-drive or hypoid circular saws are popular with professional contractors, they are heavy and do not offer much in the way of added features over the sidewinder (i.e. traditional or inline) circular saws. If you are looking for high end and powerful circular saws of 2019 then DeWalt DCS391N XR Circular Saw will be your best bet.
- Laser Guide is Useless – Do not get caught up on whether or not a circular saw has a laser guide. Chances are you won’t end up using it.
- Beware of Low End – I personally have a Black & Decker circular saw that has been through several blades and works fine for rough cuts. I would recommend it for a hobbyist who is looking for a cheap circular saw; however, you can expect these lower-end saws to have less power and cutting speed than their counterparts, and this can be a problem when cutting thicker wood. You can also expect to not have some ease-of-use features like bevel positive stops, an electric brake and an easy-change blade system.
- No Need for High End – There is not much difference between the mid-range and high-end circular saws, as the power, basic features and durability are very similar across the board.
In most cases you should look to have the blade on the opposite side of the saw from your dominant hand. So, if you are right-handed you would be better off with a left-side blade (and vice versa for lefties). This is true because you will typically have your right hand driving the saw and your left hand holding the wood — with the blade on the left side, you can have a better view of the cut line.

Works in Multitude of Applications
Cutting capacity is probably the most important specification of a circular saw. It determines whether the power tool can handle various types of sheets or materials for many different applications. With its 6-1/2 inches carbide-tipped blade, this DEWALT provides 0-50 degree bevel capacity. The depth of cut at 90-degrees is 2-1/4 inches, while in 45-degrees it can cut as deep as 1-5/8 inch.
No Power Cord
The circular saw is powered by 18V rechargeable Lithium-Ion or NiCad battery. Being a cordless power tool means that it is not necessary to keep it plugged to a power source at all times when in use. In certain job site where plenty of things, tools, and equipment are around the floor and table, a cord can be a distraction and dangerous at its worse. It is compatible with any DEWALT 18V Li-Ion or NiCad battery, meaning it is possible to use the circular as addition to the existing power tool or simply as a spare.
