Product Features

Brushless Motor: Compared to brushed motors, it is more efficient, has a longer lifespan, eliminates the hassle of carbon brush replacement, and provides longer battery life with the same amount of power.

Three speed settings: Low speed 3500r/min is suitable for polishing and deburring; medium speed 6000r/min is suitable for grinding; high speed 8000/8500r/min is suitable for efficient cutting. Select the appropriate speed according to different materials.

High-capacity battery: 4.0Ah / 6.0Ah lithium-ion battery; the 6.0Ah version offers longer battery life for continuous operation. The battery has a power level display button, allowing real-time monitoring of remaining battery power.

Slim Body: The handle is slim, comfortable to hold, and does not cause fatigue during long-term operation, especially suitable for women or delicate work.

Wear-resistant and Drop-resistant Shell: Thickened engineering plastic design, resistant to drop impacts, suitable for construction site environments.

Dual switch selection: Push-button switch (similar to a pistol switch) is suitable for one-handed operation; side switch (slider type) is suitable for frequent switching. Users can choose according to their preference.

Spindle lock: Facilitates quick and easy replacement of grinding wheels, ensuring safety and convenience.

Our Li-ion Brushless Angle Grinder vs. Ordinary Product: Why Choose BOSI?

Model Selection Suggestions

● By battery capacity: Choose 4.0Ah for occasional use and light work, as it is economical; choose 6.0Ah for long-term continuous work (such as on-site cutting and batch grinding) to reduce charging frequency.

● Based on switch preference: If you prefer a drill-like grip, choose a push-button switch; if you prefer a traditional angle grinder with a side-sliding switch, choose a side switch.

● By speed requirement: The two high-speed models are slightly different (8500 vs 8000 r/min), but the difference is not significant in actual use, and both can meet daily cutting and grinding needs.

● By budget: The 4.0Ah model is cheaper; the 6.0Ah model has a longer battery life and higher cost performance.

● Based on application scenario:

Polishing, rust removal: Select low speed, with a wool wheel or flap wheel.

Grinding welds, deburring: Medium speed, with a grinding wheel or flap wheel.

Cutting metal pipes and thin plates: High speed, with a cutting disc.
