['More Powerful & Efficient: Featured with greater arc (5° oscillation angle), more aggressive and finish project so much easier. 500w high-power motor provides great power and improves working efficiency. Compared with others with lower power motor and less oscillation angle, ours is 4 times more efficient than others in cutting wood and 2 times more efficient than others in cutting metal tubes', 'More Powerful & Efficient: Featured with greater arc (5° oscillation angle), more aggressive and finish project so much easier. 500w high-power motor provides great power and improves working efficiency.
