Bosch GWS 17-125 S INOX angle grinder 12.5 cm 7800 RPM 1700 W 2.2 kg

The Bosch GWS 17-125 S INOX angle grinder is a professional-class handheld grinding tool designed for metalworking and general construction tasks. It is powered by a high-performance 1700 W brushless motor that supports a maximum no-load speed of 7800 RPM. The grinder accepts 125 mm (12.5 cm) grinding discs with a 22.2 mm bore and combines a compact, lightweight design of 2.2 kg with a robust metal gear housing for sustained operation in workshop and site environments.

Advantages

This angle grinder offers strong cutting and grinding performance thanks to its 1700 W brushless motor, which provides improved efficiency and longer service life compared with brushed motors. The 125 mm disc diameter balances access to confined areas with effective material removal. At 2.2 kg, the tool is easy to maneuver for prolonged use, and the metal gearbox housing improves durability and heat dissipation. Designed for mains operation at 220–240 V, the model is suitable for standard electrical supplies without the need for batteries.

Suitable for

• Grinding and smoothing welds on stainless steel and other metals
• Cutting metal sheets, rebar and pipes with appropriate cutting discs
• Surface preparation before painting or coating
• Removing rust, scale and old paint from metal surfaces
• Light to medium-duty masonry tasks when fitted with suitable discs

How to use

Fit a disc compatible with a 125 mm diameter and a 22.2 mm bore, ensuring the disc type matches the intended task (cutting, grinding, sanding). Tighten the flange and guard securely before connecting the tool to a 220–240 V supply. Hold the grinder with two hands using the main handle and the auxiliary handle for control, keeping a firm stance and maintaining steady movement along the workpiece. Allow the tool to reach full speed before engaging the material and avoid excessive pressure; let the disc do the work. After use, switch off and wait until the disc has stopped completely before setting the tool down and performing any disc changes or adjustments.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, gloves and a dust mask. Select discs rated for the grinder's maximum speed and for the material being worked. Maintain the ventilation openings and gearbox area free of heavy dust and debris, and inspect the power cord regularly for damage. For tasks on stainless steel, use abrasive discs designed to minimise contamination and obtain recommended speed and feed rates to avoid overheating the material.
