Bosch Professional Corded Angle Grinder GWS 9-115 S

The Bosch GWS 9‑115 S is a high‑performance, corded angle grinder designed for professionals who demand precision, durability and versatility in one compact package. With a 900 W motor, a 115 mm (4.5‑inch) grinding wheel diameter and variable speed control, this tool delivers the power and flexibility needed for cutting, grinding, polishing and deburring across a wide range of materials.

Key Technical Specifications

• Motor Power: 900 W (1.2 HP) – sufficient to tackle tough metal, stone and ceramic tasks without overheating.
• Maximum Speed: 11 000 rpm – adjustable via the built‑in speed selector for fine control over abrasive action.
• Wheel Size: 115 mm (4.5 inch) – ideal for detailed work, small surfaces and tight spaces.
• Voltage: 240 V (European standard) – delivers consistent performance on industrial‑grade circuits.
• Weight: Approximately 1.8 kg (including auxiliary handle) – lightweight enough for extended use yet sturdy for heavy duty.
• Auxiliary Handle: Integrated – provides a second grip for better control and stability during demanding operations.

Design & Ergonomics

The GWS 9‑115 S features Bosch’s Slim Grip design, which reduces hand fatigue by fitting comfortably in the palm. The tool’s compact frame allows it to reach confined areas that larger grinders cannot access. A reinforced housing protects internal components from impact and vibration, ensuring long life even under harsh job‑site conditions.

Variable Speed Control

The built‑in speed selector lets users switch between low, medium and high speeds without the need for external accessories. This feature is critical when working with delicate materials such as glass or thin metal sheets, where excessive speed can cause chipping or overheating. For aggressive grinding on thick steel plates, the high‑speed setting maximizes material removal while maintaining safety.

Safety Features

• Guarding System: A protective guard surrounds the wheel to shield operators from flying debris and accidental contact.
• Anti‑Kickback Design: The motor’s torque curve is engineered to reduce kickback, a common hazard with angle grinders.
• Secure Wheel Attachment: The quick‑release wheel clamp ensures that the grinding wheel stays firmly in place during operation.

The GWS 9‑115 S excels in a variety of professional settings:

• Metal Fabrication: Cutting, deburring and polishing steel, aluminum and stainless steel components.
• Construction & Masonry: Shaping concrete, stone, tile and ceramic surfaces with precision.
• Automotive Repair: Removing rust, grinding welds and preparing panels for painting.
• Electrical Work: Cutting conduit, trimming cable insulation and cleaning metal fittings.

Maintenance & Care

To keep the GWS 9‑115 S operating at peak performance, follow these simple maintenance steps:

1. Regular Cleaning: After each use, wipe away dust and debris from the body, guard and wheel clamp with a dry cloth.
2. Wheel Inspection: Check for cracks or wear before mounting a new wheel. Replace any damaged wheels immediately.
