Erem OPX28010 125mm Battery Brushless Angle Grinder with Speed Adjustment 2x3Ah

Key features:

  • Brushless motor for durability
  • 4-speed rotation adjustment
  • Two 21V Li-Ion 3.0Ah batteries
  • Carrying case with accessories

Take advantage of advanced 4-speed brushless technology that delivers maximum torque and consistent performance without wear on the tool’s internal components.

  • Maximum Disc Diameter

    From 115mm to 150mm, it satisfactorily covers most amateur and professional tasks. The cutting depth ranges from 30mm to 40mm. A smaller disc diameter means that the wheel will be more flexible for simple tasks (e.g. electrical, plumbing, or DIY projects).

    From 180mm and above, it concerns industrial applications that require a larger cutting/sanding surface. The cutting depth is from 70mm and above.

  • Speed Setting

    Helps with tasks that require less speed and more detail such as sanding, polishing, DIY projects.
  • Number of Batteries 2

  • Ah

    More amps means that the wheel will work for a longer time until the battery runs out. Usually, 5 to 6 amps (Ah) are enough for most tasks.

  • Brushless

    The advantage that brushless motors have over brushed ones is that they do not have friction since there are no carbon brushes. Without carbon brushes, the motors are more efficient and have a longer lifespan as there is no wear (the carbon brushes in brushed motors wear out with use). They produce less noise, maintain constant torque at all speeds, do not overheat, and require no maintenance.

  • Brushless motor: Ensures higher performance, lower operating temperature, and increased tool lifespan.
  • 4-speed adjustment: Allows selection between 3500, 5000, 6000, and 7500 rpm for complete control depending on the material.
  • Two 21V batteries: Provide continuous operation and eliminate waiting time, as you can charge one while working with the other.
  • Carrying case: Ensures easy and safe storage of the grinder along with all necessary accessories.

Top brushless technology for demanding projects

Take your productivity to the next level in the workshop or on the job site. The advanced brushless motor eliminates internal friction, preventing overheating and delivering impressive power. This allows you to make deep cuts and demanding grinding on hard metals, with the confidence that your tool will perform flawlessly in every tough task.

Absolute flexibility with 4 speeds and double power

Adjust the wheel speed exactly where you need it. With the ability to choose between 4 speed levels, you can do everything from careful surface grinding to fast cutting of steel pipes. At the same time, the two powerful 21V Li-Ion batteries with a 3.0Ah capacity give you the full autonomy you’re looking for, without the hassle of cables and interruptions.

Ergonomic design with emphasis on safety

Work with absolute comfort, stability, and safety even in the most hard-to-reach spots. The slim body of the grinder, combined with the non-slip handle, reduces fatigue in your hands. The additional side handle can be easily mounted on the right or left so you have full control over your movements, while the guard effectively protects you from sparks.
