A Decent Little Chainsaw for the Job, But Don't Expect Too Much

I've learned the hard way that having the right tool can make all the difference when it comes to DIY projects. The more specialized tools you have, the better.

Recently, I've purchased a plot of land that's off the grid, which means I'm stuck using generators and battery-powered tools.

This review is all about one such tool: the JunLong 21V Angle Grinder with Brushless Motor 125mm. I picked it up for cutting and grinding metal sheets, and if it holds up, I'll use it for cutting pipes too.

JunLong 21V Angle Grinder with Brushless Motor 125mmI've been using it for a week now, and I'm impressed with its build quality. The buttons feel solid, and the battery life is better than I expected.I've got a big project coming up, and tools like this one will be a lifesaver.

I bought this angle grinder through a third-party seller, and my main criteria were price and power. I've seen some super manual angle grinders that come with a carrying case and two batteries, but they're only good for cutting sheet metal and are pretty weak.So, I opted for this slightly more powerful option.

JunLong 21V Angle Grinder with Brushless Motor 125mmThe packaging is pretty basic - just the angle grinder, a key, and a protective cover.

JunLong Angle Grinder with a 125mm 21v Brushless MotorJunLong Angle Grinder with a 125mm 21v Brushless Motor✅I picked this angle grinder up for 2100 rubles (that's the price from 2025)

It's not bad for the price, but I did need to note that the battery isn't included in the package.👈

I had to get a separate battery for it, which cost me another 800 rubles. But I managed to find a better deal - a car wash for 800 rubles came with two batteries, which I repurposed for this angle grinder. It's clear that the car wash is just a fancy name, but at least the batteries are decent 😊

Adjusting the speedMaximum speedBy pressing the button, I can increase or decrease the voltage, which in turn affects the motor speed.

One thing that really stood out to me about this angle grinder was the maximum power output of 900 watts. It's powered by a battery, which is a game-changer for me. I love that it's got all these functional features like no-load operation, spindle lock, bevel cut, overload protection, variable speed, a detachable dust bag, and a smooth start system. Plus, it's got a system to stabilize the motor speed. That's a lot of tech packed into one tool!

With a maximum speed of 10,000 RPM, this thing can really move. The anti-vibration handle is a nice touch, and the flexible shaft is a great feature. It's also got a protective housing, a battery level indicator, and rubberized handles. You can even set it up as a stationary unit. That's a lot of thought put into the design.

One thing I was a bit disappointed about was the lack of batteries in the package. But, I guess that's not a big deal since you can just buy some separately. The spindle is M14, which is pretty standard. This is a professional-grade tool, and it shows. It's got a sleek blue color, and the part number is BB226&II. It's made in China, which is pretty common for power tools.

I have to say, this thing is pretty convenient, especially when the batteries start to run low. Here's a shot of it in action:

JunLong Angle Grinder with 21V Battery and Brushless Motor 125mmLike that wonky ventilation hole or the button that doesn't always register

There are some assembly issues with the body, but at this price point, I can forgive that

What really gets my goat, though, is the manufacturer's deception

It's just like using a full-sized grinder, with the spindle locking in place with a button press, not a key

2mm Metal is a ChallengeBut 2mm profiles are a different story - it'll cut them, but it'll also sometimes bind and overheat

So I take a break and let it cool down

JunLong Angle Grinder with Brushless Motor, 125mm, 21V.I've spent hours using this thing to get through a mountain of profile material, and it's been a game-changer. I mean, who wants to mess around with a manual hacksaw or lug a generator around for every few cuts?

I'm docking stars for a few reasons: first, the motor's still a traditional one - not the brushless motor I was expecting. Second, the build quality and component fit aren't great. And third, the overheat protection kicks in way too quickly.

So, it's a three-star product from me, but if you're just doing small projects, I'd recommend giving it a shot!
