Carbon brushes – more durable than previous-generation brushes
Grinders tested until failure for:
- Durability of the tool
- Durability of the carbon brushes
The Bosch 10-amp, 4-1/2" Angle Grinder (GWS10-45P – with paddle switch) provides pro users with a longer-lasting tool. It lasted up to 21X longer than competitor grinders, and it lasted 2X longer than the closest competitor, in independent tests. This tool was engineered to provide all-day power and extensive machine durability.
Tested and verified long life – brushes lasted up to 62% longer than the competition and 39% longer than the closest competition in independent tests Direct-motor cooling – provides for higher overload capabilities Directed air flow – diverts dust from vital components
