Professional Lithium Battery Cordless Brushless Motor Variable Speed Power Drill Rotary Hammer Keyless 10mm Drilling

Professional Lithium Battery Cordless Brushless Motor Variable Speed Power Drill Rotary Hammer Keyless 10mm Drilling. Equipped with premium ball-type impact mechanism, it generates consistent impact force for fast and smooth drilling on concrete, brick and stone. Traditional tooth-type drills produce loud noise and wear out rapidly; our ball structure effectively cuts noise and prolongs the whole machine service life. Powered by high-torque all-copper motor with no-load speed up to 1800 RPM, drilling efficiency is 25% higher than standard models. Suitable for construction projects, home renovation and pipeline installation, it greatly saves working hours and improves overall operating efficiency. Adopting hardened gears and optimized heat dissipation system, it runs more stably and resists overheating better than low-cost ordinary impact drills.
