Corded Operation

Makita N5900B Corded Operation

When you look at circular saws, you have to decide between battery-powered and corded models, right? Corded circular saws like this Makita N5900B 2000 Watts Circular Saw powers on through electricity. The power source is what gets the blades to run and perform accurate cuts. And this, no doubt, is better, in terms of high performance, in so many ways.

On the other hand, you have the battery-powered or cordless version. Unfortunately, this isn’t packed with the ability to generate a higher speed like its corded sibling. But then cordless power tools make up for the lack of high speed and power with more portability.

After all, battery-powered circular saws have a more lightweight design, hence mobility is not a concern here. However, in areas of performance, they’re slightly disappointing because of the shortage of cutting power, comparatively speaking of course.

As for Makita N5900B, it’s not at all a circular saw with limited power. And since it’s also corded, you don’t have to worry about limited runtime either. The cutting power capacity is more than just satisfactory. All thanks to the unit’s 2,000-watt motor.

So long as this circular saw is plugged into an electrical outlet, your job or project at hand is on its way to smooth, efficient completion.

Power and Speed

Makita N5900B Power and Speed

With corded circular saws like Makita N5900B, the motor rating is measured in watts. But does the wattage of a motor really matter? Well, YES it absolutely does. After all, it is the very power the motor is capable of producing. In the case of Makita’s circular saw, you get as much as 4,000 wattage power.

A generator with a 4,000-watt power rating seems perfect for running a circular saw for a host of both heavy-duty and light applications. Now keep in mind that an average circular saw is equipped with a 1,200-watt motor. So compared to that, Makita N5900B is certainly a genuine workhorse. It’s crafted for all-day operation without any hindrance!

Now let’s talk about the speed of Makita N5900B 2000 Watts Circular Saw. Speed, no doubt, is a very, very important factor because it’s responsible for spinning the blade of the power tool and cutting through different materials.

The greater part of circular saws out there on the market fall in the speed range of 5,200-5,500 RPM. In that context, the 4,100 RPM speed of Makita N5900B does seem like a disappointment BUT also bear in mind that a higher RPM doesn’t necessarily translate into a better ability to cut through thicker materials, even though it paves the way for faster cuts.

Just as long as the speed isn’t below 3,000 RPM, you’re in good hands. With this particular Makita model, the performance is precise and powerful despite the slightly lower 4,100 RPM speed. The proof – the blade goes through beams like it’s going through butter!

So don’t be mistaken, this Makita workhorse is built to cut through thick material. And to be honest, 4,100 RPM is a pretty decent speed well appreciated by both professionals and DIY home enthusiasts.

Depth/Bevel Adjustments and Precision

Let’s talk about precision first and foremost. Every good circular saw performance is marked by precision. Whichever type of circular saw you own should cut straight, square each and every single time. So how is that made possible with Makita N5900B? With the inclusion of the right kind and quality of blades!

The fact that this power tool is priced in the $300 range means it’s not a run-of-the-mill circular saw. On top of that, the manufacturer is Makita, a brand well-known for its top quality, highly professional products. So there’s no room for complaints about the N5900B model not being able to cut precisely enough.

Speaking of the blade design, with a larger number of teeth, the cuts become finer and smoother. In that case, 48 teeth seem perfect enough for normal cuts.

Moving on to the blade type and size, what is the blade diameter? It’s 9-1/4 inches, which is certainly larger in comparison to the standard size of 7-1/4 inches. More compact models (mostly cordless) are outfitted with even smaller blades than the standard version.

The blade diameter matters in that it has an impact on the cutting depth. This means larger blades are better equipped at cutting through thicker materials. So you can breathe a sigh of relief because Makita N5900B features a blade with a larger diameter (9-1/4 inches).

What about the depth and bevel adjustments of the blade? Makita’s circular saw here is outfitted with levers that facilitate depth and bevel adjustments. The maximum cutting capacity at 90 degrees is 85 mm and at 45 degrees is 60 mm. As for bevel cuts, you can adjust the bevel angle to around 50 degrees.

Blade Visibility

Blade visibility is such an important factor yet not many people talk about it. And I don’t understand why that is because being able to view the blade during the cutting process is a must. Only then can you direct your circular saw easily and accurately along the mark. Thus, the importance placed on the debate between right-hand and left-hand orientation.

A right-handed circular saw design consists of the blade placed on the right of its motor. That means you’re holding the handle, the main one, with the right hand. While the other front handle is grabbed with the left hand. As a result of which, if you’re right-handed, then no arms or hands are going to cross over one another.

Moving on to a left-handed circular saw, its blade is positioned on the left of the motor. The main handle, in such a scenario, is gripped using the right hand while the auxiliary one is held with the left. And this, no doubt, causes the left hand to cross over that blade. In short, not the most ideal setup, right?

But then the upside to left-handed circular saws is that the hand positioning gives you more blade visibility. With these, you can view the cutline with greater visibility to cut better.

Nevertheless, the ideal choice is to choose a right-handed saw like Makita N5900B if you have a natural right-hand orientation. While the left-handed version is for lefties.

But then you have the setback of not being able to view the blade as well as cutline very clearly. You may feel the need to turn the head slightly for seeing the blade, which, to be honest, is not such a big deal. It’s better to be able to hold and handle the circular saw properly for a well-balanced, steady, and safe application.
