Bosch GWS 6-100 Angle Grinder: 11000 RPM, 100 mm Disc, Practical Option

The Bosch GWS 6-100 angle grinder (4-inch ) is a corded electric power tool designed for grinding, cutting, deburring, and surface preparation. It features a 100 mm disc diameter, a no-load speed of 11,000 RPM, an M10 grinding spindle thread, and a listed weight of 1.8 kg. It is suitable for workshop, fabrication, and general maintenance tasks when used with the correct attachment.

Working Principle

The Bosch GWS 6-100 uses an electric motor to rotate a spindle at high speed. A compatible grinding or cutting disc attached to the spindle performs the required operation through controlled contact with the workpiece.

The operator selects an appropriate accessory for the material and task. Grinding discs remove material, while suitable cutting discs cut compatible materials. The tool must be used with the correct guard, handle, and accessory specified by the manufacturer.
