Bosch GGS 28 CE Professional Straight Grinder

Bosch GGS 28 CE Professional Straight Grinder is a corded tool for grinding, deburring and finishing metal surfaces. Its 650 W input power suits professional workshop, fabrication, maintenance and precision metalworking tasks. Adjustable speed spans 10,000 to 30,000 RPM, allowing the rotation rate to be matched to different accessories and applications. Lower settings provide additional control during detailed work. Higher settings support faster material removal where the fitted accessory permits. Bosch Constant Electronic helps maintain the selected speed while the straight grinder is under load.

The compact cylindrical body weighs 1.4 kg and has an ergonomic design intended for controlled handling. Soft start brings the accessory up to speed gradually rather than applying full speed immediately. KickBack Control helps limit sudden tool movement if the fitted accessory jams. Direct motor cooling supports consistent operation during workshop use. The 230 V mains connection is intended for locations with a compatible electrical supply.
