The Bosch GGS 28 LCE is designed with a robust and slim housing, making it easy to handle even during prolonged operations. Its construction features a metal gear head for superior durability and precision alignment, while the compact 650-watt motor delivers exceptional performance under load.

The design supports ergonomic working postures — minimizing fatigue during long grinding sessions. The vibration-reducing handle and lightweight structure are built to keep productivity high without compromising safety or precision.

Key Technical Aspects:

  • High-quality ball bearings for extended service life.
  • Reinforced protective housing for heat dissipation.
  • Slim, cylindrical body ideal for confined spaces.
  • Soft-grip handle design for better tool control.

Motor & Performance: The Power Within

At the core of the Bosch GGS 28 LCE Professional Straight Grinder lies a 650 W motor, delivering steady torque across various applications. The constant electronic control maintains the selected speed under load, ensuring consistent grinding results even on tough materials like steel or iron.

This motor’s design minimizes vibration while maximizing output — making it ideal for precision grinding, deburring, and metal polishing. The speed control dial allows professionals to fine-tune performance, from delicate surface finishing to aggressive grinding.

Performance Highlights:

  • Input Power: 650 Watts
  • No-load Speed: 10,000 – 28,000 RPM
  • Constant Electronic Speed Regulation
  • Overload Protection Mechanism
  • Optimized Airflow for Motor Cooling

Speed Control & Electronic Features

One of the defining advantages of the Bosch GGS 28 LCE is its variable speed feature, a technology that ensures precision in every operation. The adjustable speed range allows operators to match tool speed with the nature of material — whether it’s soft aluminum or hard steel.

The Constant Electronic (CE) system developed by Bosch ensures that speed does not drop during load, providing smooth and uniform material removal. Additionally, the soft start feature prevents sudden jerks at startup, extending the life of accessories and improving operator control.

Applications Across Industries

The versatility of the Bosch GGS 28 LCE makes it a staple in multiple industries. It’s widely used in automotive component finishing, metal fabrication workshops, mold making, and industrial maintenance units. Its ability to reach narrow, hard-to-access areas makes it an ideal tool for precise internal grinding and polishing.

Common Applications:

  • Deburring of welded joints and edges.
  • Polishing and smoothing of metallic surfaces.
  • Finishing dies and molds.
  • Removing rust, burrs, and welding slag.
  • Shaping and contouring complex components.

Safety & User Comfort

Bosch engineers have integrated a range of safety features to protect both operator and machine. The restart protection ensures the tool does not automatically start after a power interruption. The overload protection prevents motor burnout during continuous heavy usage.

Furthermore, the vibration control system reduces user fatigue, making it possible to use the grinder for extended durations. The ventilation slots are strategically placed to keep the motor cool, ensuring steady performance and a longer lifespan.

Tool Compatibility & Accessories

The Bosch GGS 28 LCE supports a wide range of grinding accessories, allowing it to adapt to various applications. Whether you’re using mounted points, carbide burrs, or abrasive stones, the collet design ensures a secure grip and balanced rotation.

Compatible Accessories:

  • Grinding stones (up to 50 mm diameter)
  • Carbide burrs
  • Flap wheels
  • Wire brushes
  • Polishing attachments

These accessories transform the grinder into a multi-purpose precision instrument, suitable for tasks ranging from fine detailing to rough material removal.
