When selecting a circular saw you should keep these tips and techniques in mind. If you’re selecting a power saw to use for your own projects this article will surely help you.
What size Circular Saw do I need?
This could mean a couple of things 1. Size as in how big of a saw 2. Size as in how much power it has. Our reference is how big of a saw and the reason for this is you need to be able to lift the circular saw and often use it with one hand.
There are 3 basic circular saws to choose from battery operated are you smallest and lightest circular saws. The medium size are your most common sizes used and have more power than the battery operated counter part. The larger circular saw are also know in our arena as the worm-gear saw. Mostly because of the fact that the drive that turns the blade is on a worm-gear instead of direct to the motor.
What Circular Saw Blade do I need?
Again just like the saw itself the type of blade will depend on the project you need it for and the types of blades are too numerous to list. The thing to keep in mind is the thickness of the material you are cutting through and the type of material.
The more teeth the finer the cut and therefore you want to make sure to use the right amount of teeth on a blade for your project. Fewer teeth will cut faster but will also leave more splinters and a rougher looking cut.
Do’s and Don’ts
When cutting finish or cabinet grade plywood do use a blade with more teeth for a finer cut. Don’t use a rip blade for finish or cabinet grade plywood.
Do always use safety equipment when operating a circular saw.
Power and Performance
Delivering 3,700 RPM, the DCS391 is 10 percent more powerful than previous DEWALT 6.5-inch cordless circular saws. This, combined with a new 3.0 Ah lithium-ion battery that provides up to 57 percent more run time versus leading 18-volt lithium-ion tools, leads to a faster speed of cut and the power needed to make the most demanding cuts with ease.
Its powerful 460 max-watts-out (MWO) motor delivers the power and speed needed to make demanding cuts, and the three speed settings give professionals the option to select the most appropriate speed for a given task. DEWALT-designed electronics have been built into the circular saw’s switch to provide maximum life for the tool and battery by helping to protect them from overheating, overloading, and deep discharge during use.
The included charger has dual voltage capabilities, and it is compatible with both 12-volt max and 20-volt max DEWALT lithium-ion batteries.
