SEESII Flathead Brushless Angle Grinder, 21V 5.0Ah, 6-Speed, 4-1/2 to 5 Inch Cut Off Kit

Overview

Meet the SEESII Flathead Brushless Angle Grinder, a compact, high‑performance tool designed to fit into tight spaces. Its ultra-thin flathead gear housing reduces head thickness by 30–40%, helping you reach narrow gaps and corners with ease. This design makes it possible to flush-cut bolts and grind in spots where bulkier grinders can’t reach, offering practical versatility for real‑world jobs in metalwork, auto body, and DIY projects.

Powered by a brushless motor, the grinder delivers up to 30% higher efficiency with less heat and lower noise. You get consistent high torque from start to finish, so you can maintain momentum through demanding tasks without stalling. The result is a tool that feels reliable from the first pass to the last, whether you’re smoothing welds, removing rust, or finishing edges.

Safety and control you can rely on

• Gyro Safety Stop monitors orientation and abnormal motion, cutting power within milliseconds to help prevent slips and accidents.
• Auto-Reset Overload Protection automatically protects the motor and resets when conditions clear, minimizing downtime.
• Tool-Free 360° Guard lets you rotate and lock the guard with one hand, directing sparks away from you and your workpiece.

Versatility at your fingertips

• Six electronic speed settings (3,000–12,000 RPM) let you switch from delicate surface polishing to aggressive material removal without swapping tools.
• Constant power output under load keeps performance steady, no matter the material—metal, stone, tile, wood, or plastic.
• Ergonomic, balanced design (1.8 kg without battery) plus a detachable side handle supports comfortable use for extended sessions.

Power, runtime, and quick recharge

The 21V 5.0Ah high-discharge battery (10C) offers extended runtime, while the included fast charger recharges in about 2.5 hours. This setup helps you stay productive with fewer interruptions on longer projects.
