Buying just about any cordless circular saw and then expecting it to upgrade your woodworking skills and performance is like shooting in the dark. But with this Milwaukee cordless circular saw, you’re not indulging in any kind of such gamble. Bare-Tool Milwaukee 0740-20 V28 is indeed a high-performing, very efficient cordless model that produces the most accurate bevel cuts.
Don’t let unnecessary, impractical fancy features and performance metrics be the deciding factors. Instead, prioritize characteristics like power-to-weight ratio, cutting depth capacity, bevel capacity, etc.
In that light, this battery-powered circular saw is a sweet deal indeed. It’s a high-powered, 28V tool with a speed of 3,200 RPM. As long as the cordless circular saw is furnished with a battery supply over 20V, you don’t have to worry about not reaping the full convenience and benefits often accompanied by a cordless unit. And this is long-term convenience and rewards!
Another very important, hence very influential deciding factor is the type of circular saw. This is where the debate between sidewinder and worm drive comes into the picture. Milwaukee 0740-20 V28 is the former. And just because of that, it offers more lightweight maneuverability, hence easy, convenient handling.
Sidewinder circular saws also pave the way for a shorter, wider profile in comparison to the worm drive. A compact cordless circular saw like this is surely something those new to the task of woodworking would appreciate.
This sidewinder mechanism, which just means that the motor is installed at the side, utilizes spur gear for making the blade perform rotations per minute to its max. capacity. In this case, that would be 3,200 RPM.
How much friction gets in the way of things can either make or break your experience with a circular saw. And this matter of friction plays a huge role when talking about the differences between brushless and brushed motors.
First of all, Milwaukee 0740-20 is equipped with a brushless motor. The best part about brushless motors is that they generate less friction in comparison to their brushed counterparts.
The efficiency rating you get with a brushless cordless power tool like the current Milwaukee circular saw is anywhere between 85 and 90 percent. And this is certainly more than the 75-80 percent efficiency output gained by brushed motors.
To be honest, the difference doesn’t seem like much. But as far as battery-operated, cordless performance goes, it matters a great deal. Why is that? Simply because the loss of minimal power to friction means a higher efficiency value. So all the power that’s not used up by friction is put to better use by the blade. Hence, maxing out usage on a single battery charge.
So it’s not surprising to know that Makita has equipped its cordless circular saw here with a brushless motor. Higher efficiency is a top priority indeed if you want the blade to be more powerful and create higher RPMs and torque.
Apart from efficiency rating, what a brushless motor is also responsible for is producing less heat. Thus, it’s the least likely to cause overheating problems during long and/or heavy applications.
Blade Size / Cutting Capacity
By no means is the Milwaukee 0740-20 V28 a small cordless circular saw. Because then if that would be the case, the blade size would be between 4-1/2 inches and 5-1/2 inches. Rather the blade diameter here is 6-7/8 inches. Although 7-1/4 inches is even larger for a high-end circular saw.
In that context, Milwaukee 0740-20 V28 is more of a middle-ground model. Its 6-7/8 inch blade can cut 2 inches deep in a single pass. In fact, it also cuts 2-1/8 inches deep. But for 2-1/2 inches, it’s better to go for circular saws outfitted with a blade size of 7-1/4 inches.
So if you’re not really impressed with the blade size and cutting depth, please understand that what matters more with this Milwaukee creation is that it hands out more control during the cutting operation. And that is done in the most effortless manner, all thanks to the tactile grips.
Likewise, the light magnesium guards minimize unnecessary weight while also maximizing operation. Moreover, there’s the heavy-duty yet lightweight steel shoe that’s bend-resistant just to incorporate the highest level of reliability and accuracy.
So what Milwaukee here might lack in terms of cutting capacity or blade size it just as well makes up for in providing uncompromised control, precision, and overall smooth operation.
