Power Concrete Screed Vibratory Kit, 21V Electric Cordless Concrete Screed Vibrator Tool Concrete Finishing Tool Battery Powered Concrete Surface Leveling Tamper Ruler for Construction Sites

Durable & Sturdy: The thickened and widened stainless steel scraper ruler, the aluminum alloy motor's shell, and the thickened aluminum machine's head, combined with spray paint, offer wear prevention and long-term service life. | Stable Running: The two extra stainless steel reinforcing rods are fixed on the scraper ruler separately, which form a stabilizing triangle structure that can provide a more stable operation experience. | High Working Efficiency: The brushed all-copper motor has a power of 48W, a rotating speed of 3000-6000r/min, and a vibration frequency of 23000Hz/min. Also, the equipped 7500mA battery is fully charged and can be used for about 2-3 hours continuously, making your leveling work be finished quickly and easily. | User-friendly Design: It only weighs 11.68 lbs and has a portable handle, making it convenient to carry to different workplaces. The cordless design reduces usage restrictions and provides you with more flexible space. The power switch safety lock can keep the machine running without pressing the switch with a hand all the time, reducing hand fatigue. | Save Cost & Energy: Compared with gasoline vibration leveling machines and manual ground leveling, its vibration motor has an ex-factory precisely tuned vibration frequency and amplitude to eliminate internal bubbles in concrete, enhancing density and uniformity.
