Angle Grinder Bosch GWS 17-150 S

The Bosch GWS 17-150 S angle grinder is a professional-grade power tool designed for demanding grinding and cutting tasks. It features a high-performance 1700 W brushless motor that provides stable power delivery and improved durability. With a 150 mm (15 cm) grinding disc diameter and a bore size of 22.2 mm, the tool achieves an idle speed of up to 9,700 RPM, enabling efficient material removal and fast cutting progress. The grinder is compact and lightweight at approximately 2.2 kg and is finished in Bosch’s characteristic black and blue design. It operates on standard AC mains voltage of 220–240 V for reliable on-site or workshop use.

Advantages

The brushless 1700 W motor offers higher efficiency and longer service life compared with brushed motors, while delivering the torque needed for continuous heavy-duty operation. A 150 mm disc diameter balances reach and control for common grinding and cutting tasks. The 9,700 RPM no-load speed supports rapid material removal and clean cuts. At about 2.2 kg, the tool is relatively lightweight, reducing operator fatigue during extended use. The tool’s mains operation ensures consistent power without the need to manage battery charge.

Suitable for

• Metal grinding and beveling on steel and iron
• Cutting steel rebar, profile pipes and sheet metal
• Surface preparation such as rust and paint removal
• Masonry cutting with appropriate discs

How to use

Fit a disc compatible with a 150 mm diameter and 22.2 mm bore, and ensure the correct disc type for the intended material. Securely tighten the disc flange using the provided spanner and remove the mains plug before any adjustments. Hold the grinder with both hands, using the auxiliary handle for better control and positioning. Start the grinder and allow it to reach full speed before engaging the workpiece. Apply steady, even pressure—avoid forcing the tool—to maintain control and prevent disc overload. After completing the task, switch off the grinder and wait for the disc to stop completely before setting it down or changing accessories.

Usage recommendations

Use discs rated for the grinder’s maximum speed and select abrasive type according to the material. Wear appropriate personal protective equipment including eye protection, hearing protection and gloves. Ensure adequate ventilation when working on coatings or materials that produce dust, and use dust extraction where possible. Allow periodic cooling intervals during continuous heavy work to preserve motor life.
