5. PORTER-CABLE PCC660B
More detailed review ↴
The Porter-Cable circular saw is another go-to fast cordless circular saw that would do the job for you without breaking a sweat. However, during operations, its blade can sometimes drift to a direction away from the wood cutline. This is probably due to a flawed design.
The saw’s body and shoe connection is located at the edge of the upper guard cluster. The plastic is particularly amenable even though the prevailing temperature may be room temperature.
It becomes increasingly looser when it is exposed to sunlight. Without anything sizeable keeping the blade firm and straight, the body of the saw would point the cutting edge into the cut when you thrust down on the saw.
To ensure that this saw functions correctly, it requires a strong hand to steady the body, and executing the deepness of the cut as much as you like can prove to be helpful.
- Lightweight: It is a lightweight option.
- Bevel cutting: The circular saw produces profound bevel cutting.
- Cutting Edge: It comes with a 6-1/2″ cutting edge that provides a 2-1/8-inches cutting ability.
- Its wiggly build makes it short of precision and power.
- It is somewhat sluggish and makes cutting difficult.
Best Battery-Powered Circular Saws — Buyer’s Guide
There are some things that you need to consider when you go all out to buy a cordless circular saw for your woodworks. These include the features that it comes with, the size of its blade, its power output, and its build style. Below are some of the other options that you should consider too:
Worm Drive vs. Sidewinder
Carefully considering whether the cordless circular saw that you are about to buy features a worm drive or a sidewinder is a wise decision. It is currently one of the passionately discussed topics in the woodworking industry. What side of the fence are you on? Let’s see!
Sidewinder saws and worm-drive saws are different in the way their motor is positioned. The motor of the latter is attached to its rear side and interacts with the blade through two gears – a spiral worm gear and one other gear type – which conveys the energy of the motor to its blade.
Due to the indirectness of this configuration, most blades that are worm-driven do not rotate as quickly as what is obtainable with the sidewinder blades, reaching the highest speed of just 4,500 rpm.
Also, a saw with a worm drive uses bigger gears, and this provides it with greater torque than that offered by a sidewinder, letting it better absorb shock and handle harder cutting tasks.
Worm-driven cordless circular saws also have a narrower and longer profile than that of the sidewinder saws, and this broadens the user’s reach and gives room for tighter spaces.
As a result, they are the perfect tool for framing and remodeling. Sidewinder circular saws feature motors that are positioned on the side of the saw and render the profile lighter, shorter, and wider than that of the worm-driven saws.
This packed build makes it simpler to use and more suited for novice operators. Sidewinder saw utilize spur-gear to spin the saw’s blades at around 6,000 RPM.
Previously, the cordless circular saws in the market are not as effective as their corded counterparts. Courtesy of the progress made in battery technology, this power bridge has dramatically been closed.
It is astonishing but true that many manufacturers keep churning out cordless circular saws that are more effective than the corded saws. The power rating of circular cords is estimated in rpm (rotations per minute).
Most of the cordless circular saws in the market have four thousand rotations per minute, with first-rate saws having close to five thousand rotations per minute, or even more.
Saws would have a greater cutting potential if they have higher rotations per minute. Do not forget that rotation per minute is not ultimately a great indication of torque.
Although worm drive cordless circular saws may feature lower rotations per minute than their sidewinder counterpart, their build provides it with more torque.
You should look out for the power rating of the saws when looking to make a decision.
Because of the considerable power needs of circular saws, cordless saws come with a rechargeable 20-volt or 18-volt Li-ion battery that is attached to the saw.
A lot of saw-making brands build their batteries to function interchangeably with the whole power equipment lineup, including cordless saws. You need to ensure that your choice has reliable batteries. More so, if it has batteries that function interchangeably across multiple devices, then it is a huge advantage.
Due to the fact that cordless circular saws normally do not have the amount of power than its corded counterpart does, most of them cannot deal with a complete 7¼” blade well.
While it is true that smaller blades will offer greater torque because of the ease with which their motor turns, their cutting depth is their undoing.
Most of the cordless circular saws out there come with 6½” blades, though a handful of high-end circular saws utilize 7¼” blades.
The former offers the highest cutting depth of about 2⅛”, while a bigger 7¼” blade will cut through a 2-7/16” depth. Smaller circular saws will come with both 4½” blades and 5½” blades.
Pay attention to these details in any chosen saw and see to it that the blade size matches your cutting needs.
Brushless vs. Brushed Motor
The major distinction between brushless and brushed motors has everything to do with the effect of frictional forces.
Without going deeper into the working principles of each of these motors, it is important to note that brushless motors generate less friction, and as a result, they have efficiency ratings somewhere between 85 – 90%.
In contrast, brushed motors, because of their design, lose a lot of energy due to frictional forces, and this hinges their efficiency values to around 75 – 80%.
While it is true that this disparity may not be so significant for a corded saw that can access an enormous voltage supply of 110V, it has a real effect on a cordless saw. Less energy would be lost to friction when the efficiency rating of the motor is higher, and this implies that a greater part of the power of the battery would be dedicated to the rotation of the blade. This means extra cuts before the saw’s battery finally runs down.
A greater efficiency mark also implies that a twenty volts battery can commit more of its power to make the blade turn, leading to greater maximum rpm and additional torque. Some of the most effective cordless circular saws in the market, like those with the ability to turn 7¼” blades, utilize brushless motors.
And because brushless motors do not produce as much friction as brushed motors, they generate a lesser amount of heat. This decreases the incidence of overheating and may cause some serious harm to the motor.
Most cordless circular saws come with comparable safety measures to those of their corded counterparts. Some of them include retracting blade blocks and blade guards that instantly halt the blade immediately there is a release of the trigger.
Also, cordless circular saws activate safety measures to avert the occurrence of unintended experiences. Some other safety measures that it comes with include molded holds that are coated with rubber that stop the equipment from slipping through the hands of the operator.
Now we all know that saws are very efficient tools, yet, they can be devastatingly dangerous when accidents happen. Therefore, when buying a cordless circular saw, it is highly imperative that the one you chose has important safety inclusions.
Aside from the common features like depth and bevel adjustments those cordless circular saws come with, they also have innovative systems built to make them more durable. Some makers have built their saws in such a way that they’ll simply shut off when there is a problem of overheating.
Most first-class saws include waterproof materials that block the entrance of dust and water, conferring to them the ability to endure the cruel environment that characterizes open-air worksites. Eventually, some of these saws will adjust to speed and torque contingent on their workload to maximize their performance.
