The Spin Screed Battery Operated Spin Screed Power Heads are the world’s first lightweight power roller screed designed with the professional concrete finisher in mind. Their lightweight design makes it even easier to screed large concrete surfaces while also keeping your aggregate near the surface, which helps produce stronger, flatter concrete slabs. The cordless Battery Operated Screed assembly adds even more convenience with its rechargeable, battery-operated cordless drill (36V Makita Right Angle drill), four 18V 5.0 ah Makita batteries, and dual battery charger. Both Power Head options come with an impact socket adapter, a dead-end T-handle, and live and dead ends. These Screeds are Made in the USA with Global Materials.
