Lanrui F2 Electric Grinding Pen

Precision Grinding for Electronics Repair Professionals

If you work with circuit boards, chip ICs, or delicate electronic components, having the right tool makes all the difference. The Lanrui F2 Electric Micro Grinding Pen is designed specifically for precision tasks that demand control, consistency, and reliability — whether you are a seasoned repair technician or a dedicated electronics hobbyist.

Built for Detailed Repair Work

The F2 is not a general-purpose rotary tool. It is engineered for fine work: grinding down motherboard components, cutting brackets, cleaning solder points, and loosening stubborn IC chip screws that standard tools simply cannot reach. The slim 130x17mm body fits naturally between the fingers, giving you the same feel and control as a quality pen or precision screwdriver.

Three-Speed Control for Every Application

One of the most practical features of the Lanrui F2 is its three-speed adjustment system. You can run the motor at 10,000 RPM for delicate surface work, step up to 15,000 RPM for moderate grinding tasks, and push to 20,000 RPM when you need maximum cutting power. This range of control means you are never forced to use a single speed for every job — you adapt the tool to the task, not the other way around.

Powerful Yet Compact

Despite its lightweight 100g build, the F2 packs a 10W motor with a built-in 380mAh battery. That is more than sufficient for extended repair sessions without needing a continuous power connection. When the battery does run low, the Type-C charging port means you are never hunting for a proprietary cable — the same charger you use for your phone or other devices works here.

Secure Grip with 2.35mm Chuck

The 2.35mm fixture with a 25mm chuck depth ensures that grinding heads stay firmly locked during high-speed operation. There is no wobble, no slippage, and no interruption to your workflow. The package includes six grinding heads, giving you immediate variety for different surfaces and materials right out of the box.

Practical for Pakistan's Repair Market

For mobile repair shops, computer technicians, and electronics enthusiasts across Pakistan, the Lanrui F2 offers a professional-grade micro grinding solution at an accessible price. It removes the need for bulky bench grinders or expensive imported tools when working on everyday repair jobs.

Whether you are removing stripped screws from a phone motherboard, trimming a PCB bracket, or cleaning up a soldering area, the F2 handles it cleanly and efficiently.
