Makita 9557PB Review: Key Features

Cutting Performance

For such a small angle grinder, the 9557PB packs quite a punch. It is equipped with a powerful 7.5 amps motor and the recorded no-load speed is 11,000 RPM. With this sort of performance, the Makita 9557PB can easily cut through metal and handle heavy-duty workloads.

Quite impressive for a small angle grinder.

Additionally, Makita has a few tricks up its sleeves to further improve the grinder’s performance. They wrap the motor’s armature with high-gauge wires, which reduces heat transfer from the motor to the rest of the grinder. It improves performance while ensuring that the grinder won’t heat itself up to the point of burning your hands.

The motor’s hum is loud, so it’s best that you wear earmuffs if you’re going to work with it for long periods.

Overall Body Design

The design is the Makita 9557PB’s selling point. It has a very compact body, which makes it an excellent angle grinder to use when you have to work in cramped spaces. The grinder is also fairly lightweight at 4.5 pounds.

Makita 9557PB has a traditional design: a metallic gearbox attached to a plastic handle that houses the motor.

The plastic handle is attached to the side of the grinder, providing better handling and a stronger, more comfortable grip. This handle is long enough that you can still see the object you’re grinding while holding the grinder with both hands.

Overall, the design feels very solid despite the compact size.

4 ¼-inch Wheel

The 9557PB accepts 4 ¼-inch wheels. It is a good size for small metal-working, home renovating, or DIY projects. However, if you’re a professional who needs a tool with performance to match, look to grinders with larger blade sizes.

There are many Makita angle grinders on the market that accept blades up to 9 inches.

How easy is it to change the wheel?

Changing the wheel is an annoying task on the 9557PB. First, the spindle lock has to be disengaged. It is located at the top of the gear housing. You can use a grinder wrench to take off the lock. From there, you can remove the disk.

Although it is a straightforward job, turning the lock can be a bit difficult and labor-intensive. So, if you have to change disks often, you may feel a bit frustrated with the Makita 9557PB.

Paddle Switch

The angle grinder is actuated using a large paddle switch. It is at the rear of the handle. We have found that the switch is very easy to grip and reach. Just grab the handle as normal and all of your fingers could easily reach and press it.

In the middle of the paddle switch is a guard. It stops the tool from turning on when you set it down onto a table. The guard also acts as a trigger safety mechanism. To press the paddle switch and actuate the grinder, you have to unlock the switch by pushing the guard forward.

One complaint is that the guard is a bit small, so you can’t work it by feel. You need to visually locate it. Working the switch and turning the angle grinder is difficult to do, too. As a result, handling the 9557PB can be quite difficult.

Trigger Lock

Fortunately, you don’t have to always keep your fingers on the paddle switch for the angle grinder to work. Instead, engage the lock-on mechanism. When clicked into place, the lock will hold down the paddle switch and keep it running.

To disengage the lock, squeeze the switch once more and the angle grinder will shut off.

It works very well and won’t take a lot of practice to get used to.

Blade Guard

The blade guard is a key safety component of the Makita 9557PB. It is made from solid steel and can be rotated and locked in every direction. You can fit a 4.5-inch cutting wheel into the guard.

It is attached to the angle grinder via a compression fitting made from steel. A single screw holds the guard in place. Tighten the screw and the guard won’t budge even when you rest the grinder on it.

Removing and replacing the guard is an option when it becomes worn out. Blade guards are available as replacement parts in Makita’s inventory. You can call their customer service and they’ll give you some buying options.

As you grind or cut anything (especially metal), the resulting spark is directed downward by the guard.
