About this item

• High-Torque Brushless Motor – 9000 RPM Constant Power Equipped with an industrial-grade brushless motor that maintains 9000 RPM under load with 30 % more torque and 50 % longer life than brushed grinders. Delivers consistent power for metal cutting, rebar trimming, tile grinding, and wood shaping. The built-in smart chip controller prevents overheating and current overload, ensuring stability during heavy-duty work.
• Dual 4.0 Ah Li-Ion Batteries – 2 Hours of Continuous Operation Includes two 21 V / 4.0 Ah lithium-ion batteries, each supporting ≈ 60 min of cutting time per charge (light–medium load, 10 mm steel). The fast charger recharges each pack to 100 % in ≈ 90 minutes. LED indicators show real-time power level, so you never run out mid-task. Ideal for continuous outdoor or job-site projects where corded power is unavailable.
