Kit 125mm 21V cordless brushless angle grinder M14 2x3Ah case
Looking for a reliable, extremely powerful and flexible tool for cutting and grinding without the hassle of cables? The M14 125mm 21V Cordless Brushless Angle Grinder Kit is the perfect solution for both demanding DIYers and professional craftsmen. Powered by advanced brushless technology, it provides significantly longer motor life, higher torque and up to 50% more energy efficiency compared to conventional brush motors.
Thanks to the powerful 21V system and the two included high-performance 3Ah batteries, you will get the job done quickly and without interruption. While you are using one battery, the other is already charging. With a standard M14 thread and a disc diameter of 125 mm, this grinder is extremely versatile and ready to work on metal, stone, concrete or tiles.
Key benefits of OPEX TOOLS brushless technology
A modern brushless motor provides greater performance, smoother operation and a longer lifespan compared to traditional brushed motors. The absence of brushes means fewer wearing parts, a lower risk of failure and greater efficiency during operation. In traditional brushed motors, the brushes wear out during operation, which may eventually require servicing or replacement. With a brushless motor, this problem is minimized, making the tool more practical for everyday use.

Greater efficiency: Better power utilization for the most demanding tasks.
Less energy loss: Longer operating autonomy with a single battery charge.
Maintenance-free: There is no need to replace brushes, reducing service costs and time.
Longer life: Components wear out less and overheat less.
More stable operation under load: The motor maintains constant power even during heavier cuts.
Better battery life: Up to 50% longer runtime per charge.
Quieter operation: Less noise during operation for greater user comfort.

Versatility and freedom of movement without cables
The absence of a cable gives you complete freedom of movement. You can cut and sand wherever you want – in the workshop, garage, on your property, by the fence, on a construction site or during maintenance work. You don't have to look for a socket or drag long extension cords. A cordless sander allows you to work exactly where you need it.
The popular disc size makes the tool compatible with a wide range of accessories available on the market. The 125 mm diameter discs are easily accessible and suitable for cutting metal, steel, profiles, bars, ceramics, concrete, stone and other materials. The standard M14 thread allows for convenient attachment of attachments and accessories used with angle grinders.
Precise control with 4 speed levels
Four speed ranges allow you to adjust the power of the tool to the type of material and the specific task. Speed control allows for more precise and safer work. Not every job requires maximum speed - the ability to select a speed gives you more control and reduces the risk of damaging the workpiece.

1st gear — 3500 rpm: For more delicate work, cleaning surfaces and greater control over the material.
2nd speed — 5000 rpm: For standard sanding, surface preparation and light workshop tasks.
3rd gear — 6000 rpm: For more demanding jobs and faster material removal.
4th gear — 7500 rpm: For cutting and intensive work where maximum performance is required.

Ergonomics, durability and rich equipment
The tool body is designed to withstand tough conditions – including metal dust, sparks and heavy use. The ergonomic design, well-shaped handle and side handle provide a secure grip and greater control over the tool. The side handle is suitable for both left- and right-handed users.
Two 3.0 Ah batteries increase working comfort. This is especially important for longer jobs, where one battery can be used while the other is charging. The practical case makes it easy to store and transport the entire set. The tool, batteries and accessories have their own place, making it easy to keep things tidy.

Frequently Asked Questions (FAQ)
What is the advantage of a brushless motor over a conventional one?
The brushless motor has no carbon brushes to wear out during operation. This means the motor is virtually maintenance-free, runs cooler, runs quieter, offers more torque and uses up to 50% less battery power, significantly extending the operating time on a single charge.
Can I use cutting discs from other manufacturers with my grinder?
Of course. The grinder uses a standard disc diameter of 125 mm and a standard M14 spindle thread. This means that it is fully compatible with most standard cutting, grinding and flap discs and wire brushes available on the market.
How long does it take to charge the battery and how does the two-battery system work?
The set includes two powerful 3.0 Ah batteries. The system is designed to allow continuous operation: while one battery is used for cutting or grinding, the other can be charged on the included charger. You can easily monitor the battery status via the built-in charge indicator.

Instructions for using the product:
Step 1: Charging and inserting the battery
• Fully charge the included batteries before first use using the included fast charger.
• Push the charged battery into the groove on the bottom of the sander until you hear a click.
Step 2: Installing the protective cover (Essential for safety!)
• Install the protective ring on the neck of the grinder.
• Adjust the angle of the lid so that the open part faces away from your face and body.
• Tighten the screw or latch on the cover to prevent it from moving during operation.
Step 3: Mounting the cutting/grinding disc (M14 thread)
• Press and hold the spindle lock button on the top of the grinder housing (head).
• Install the lower flange on the spindle.
• Install the desired 125mm plate onto the flange.
• Tighten the upper M14 nut by hand.
• Using the supplied wrench, tighten the nut firmly while still holding the spindle lock button.
Step 4: Installing the side handle
• Screw the auxiliary handle into one of the two holes on the grinder head (depending on whether you are right-handed or left-handed).

Useful tips:
• Correct grinding angle: When grinding surfaces, hold the grinder at an angle of between 15° and 30° to the workpiece. This will ensure optimal material removal and even wear of the disc.
• Don't overdo it: The brushless motor has high torque. Let the weight of the machine and the RPMs do the work. Too much pressure will only drain the battery faster and overheat the plate.
• Battery storage: Do not leave Li-Ion batteries completely discharged for long periods of time. If you will not be using the grinder for several months, charge the batteries to approximately 50-70% and store them in a dry, cool place.
• Choosing the right disc: Always use discs with a diameter of 125 mm, which are declared for the speed reached by this sander. Never use damaged or warped discs.

Warnings:
⚠️ IMPORTANT SAFETY WARNING: The angle grinder is a powerful, high-speed tool. Failure to follow safety instructions can result in serious personal injury.
• Personal protective equipment: You MUST wear safety glasses (or visor), protective gloves, a dust mask and hearing protection while working.
• Never without protection: It is strictly forbidden to use the grinder without the safety guard installed.
• Changing equipment: Always remove the battery from the device before changing the plate, adjusting the cover, or cleaning the tool.
• Watch out for sparks: Direct sparks away from yourself, other people and flammable materials (gasoline, rags, wood dust).
• Kickback Hazard: Be careful not to allow the disc to catch in the workpiece while cutting, as this can cause the tool to kick back violently. Always hold the grinder firmly with both hands while working.

Same summary

The 125mm 21V Cordless Brushless Angle Grinder M14 Kit with Two Batteries Included is designed for users looking for mobility when grinding metal, tiles or other harder materials. Two batteries allow for longer continuous work, which is useful for more demanding and longer projects, while the brushless motor reduces the need for maintenance and improves energy efficiency. Due to the 125mm disc diameter, the model is a balanced choice between processing speed and the ability to use it even in slightly narrow or difficult-to-reach places, but it is not the best suited for very precise or miniature tasks. This kit is less recommended for those who need an extremely lightweight tool for overhead work or hours of precise grinding, but it offers a good compromise between performance and usability in the field.
