Key Features
Variable Speed Control (Stepless)
Unlike fixed-speed grinders, this model features stepless speed adjustment. You can smoothly vary the speed to match the material, preventing burn marks on metal or damage to softer surfaces.
High-Capacity Dual Battery System (2x 4.0Ah)
Includes two 4.0Ah high-capacity batteries. This provides double the runtime of standard kits, essential for power-hungry tools like angle grinders. Never let a dead battery stop your workflow.
Powerful Brushless Motor
The advanced brushless technology delivers higher efficiency, cooler operation, and longer lifespan. It maintains high torque under load, ensuring smooth cutting and grinding even in tough materials.
Ergonomic Slim Body Design
The "slim and slender" form factor reduces hand fatigue and improves control. The textured grip ensures a secure hold, even when wearing gloves or working in awkward positions.
Standard 100mm Capacity
Optimized for 100mm (4-inch) discs, the most versatile size for general construction, metalworking, and DIY tasks. Compatible with a wide range of cutting, grinding, and polishing accessories.
