Description:
This compact angle grinder from Bosch combines a powerful motor and a slim, ergonomic body to handle cutting, grinding and surface prep on job sites and in the workshop. With an 11,000 no-load rpm rating according to the manufacturer and a comfortable Slim-Grip design, it aims to deliver high-speed performance while reducing user fatigue.
Key Points
The tool includes a two-position side handle that improves control when working at different angles. Directed airflow helps keep dust away from critical parts which can extend useful life. Service Minder brushes stop the grinder to indicate when maintenance is needed, helping avoid unexpected failures. The burst-protection guard allows quick adjustments for safer operation and the large spindle lock simplifies disc changes. Note that performance figures are those provided by the manufacturer.

Benefits
This model’s 7.5 amp motor offers strong cutting and grinding capability for metal and masonry tasks while remaining compact enough for overhead or tight-space work. The Slim-Grip body improves handling when working long shifts, and the large spindle lock reduces downtime during wheel changes. Directed airflow and durable carbon brushes are practical touches that contribute to longer service life when the tool is used regularly.
Usage Recommendations
Use the two-position handle for extra leverage on heavier cuts and switch it to the opposite side for improved balance during detail grinding. Replace the carbon brushes when the Service Minder indicates maintenance to keep power delivery consistent. Always use the burst-protection guard in the recommended configuration and follow standard safety practices including eye protection and appropriate clothing. Consider that high-speed operation is powerful but may generate significant sparks and dust, so prepare the work area accordingly.
