Professional-Grade Motor

Makita 5057KB Motor

The motor capacity of the Makita is designed for and can take on fiber-cement materials. So it’s rugged, powerful, and efficient for demanding applications. Cutting fiber-cement is not only intense but it also puts a lot of pressure on circular saw.

Thankfully, the Makita 5057KB is equipped with a 13 AMP motor with 5,800 RPM cutting speed. So without getting in the way, the circular saw can take on all your masonry work, showing immediate and effective results.

The performance tests also say that the power tool can cut 5 5/16-inch boards, especially fiber-cement sidings, in a single pass.

This is without your workstation getting filled with dust and other debris! This brings to another significant contribution of the Makita for fiber-cement cutters.

Dust Collection Mechanism

Makita 5057KB Dust Collection

The dust blowing mechanism of the Makita outperforms what I’ve generally seen in other, similar fiber-cement cutting saws. I mean did I already mention that the Makita can cut sliding boards at least 3 times more than other circular saws?

And to maintain such an amazing speed and powerful drive, you have the dust collection features. Quite a few of them actually make the Makita an intelligent pick.

The design consists of a dust collection container which holds all the debris and dust from cutting. One thing that anyone who has worked with fiber cement will tell you is that the amount of silica dust it produces, it’s a mess. Not only that but it can be harmful for your lungs as well.

Now, you’re supposed to wear the proper protective gear while using a circular saw. Whether it’s fiber cement you’re cutting or plain old wood, protective gear is not optional.

Thanks to the dust container, the Makita collects large amounts of dust without you having to vacuum it.

Moving on, there’s even a dust port at the rear end of the housing to attach a vacuum connection. Yes, since it’s at the rear end, not the side, it might seem a bit interfering. But I don’t see that as a major inconvenience.

Dust-Proof Durability

Makita 5057KB Dust Proof Durability

There’s no denying that the Makita is prepared for intense use. For starters, it features dust-proof bearings including a dust-proof switch that prolongs the shelf life of the power tool.

It protects the motor from getting flooded in debris. And the blade is protected too with a retractable blade guard. These are obvious signs that the Makita is durable and will outlast many competitors within the same price range.

But the not-so-obvious features that contribute to the Makita’s overall durability are the shaft lock, offset wrench, and rip fence.

The shaft lock keeps the blade in the right position during use and also for quick and seamless blade changes. And speaking of blade changes, I’m quite impressed with the offset wrench too. It’s sturdy, strong, and easy to work with.

You can easily retract the blade guard for more intricate, plunge cuts. Combined with the whopping 5,800 RPM cutting speed, it slices through without so much as a noise or lag.

Blade Adjustability

The Makita has a 7-1/4-inch circular saw blade coupled with a few extra adjustments. Such as you can make plunge cuts by retracting the blade guard, for starters. This makes the Makita unique and productive in many ways.

Next, you have the bevel flexibility from 0 to 45 degrees. This is a convenient ratio for making quicker, more precise, and consistent cuts. Especially when working on fiber cement that is already a tricky material to use.

It’s truly remarkable how effective and precise this circular saw is. It rises above the competition, for sure, for the best flexibility and ease of use.

And features like the bevel, retractable blade guard, and sturdy footplate make it even better.

The blade cutting capacity includes rip fence for super-straight and sharp cuts. You can use other blades too because the shaft lock is sturdy and allows quick and easy blade changes.

The bearings that make up the design of the Makita are dust-proof and stable. Compatible for intense and demanding applications, it does accommodate a wide variety of cuts without any inconveniences.
