The STGS9100 features a 900W high-performance motor and a 100mm (4-inch) disc capacity, making it suitable for a wide range of cutting and grinding applications. Its compact housing and anti-slip grip provide improved handling and control during operation.

The grinder uses spiral bevel gears to help reduce vibration and operating noise while improving gear durability. A soft-start function allows the motor to build up speed gradually, helping provide better control when starting a cut or grinding operation.

It also features a spindle lock for quick accessory changes, a protective guard for user safety, and an ON/OFF slide switch for convenient operation. The standard STGS9100 specification uses an M10 spindle and supports grinding discs up to 6mm thick.
