Cutter Heads TH Twin Drum Cutter Heads
Asphalt & Concrete Cutting Work speedy and powerfully
TH series is good for road repair work and assisting work with large cutting machines.
Realize speedy and powerful cutting work at the job site of quarry, asphalt & concrete cutting and hard soil excavation.
This can also be used with a dual pump confluence system!
A bit cutting method achieves low noise work.
Equipped with a flow control valve, it can be used with a dual pump confluence system as well as with a single pump system. A unique drum rotation mechanism achieves powerful excavating and cutting ability. In addition, a bit cutting method enables lower impact and lower noise cutting work than breakers and others. A compact and simple design is also highly perceptible.
Cut with dual drum round bits.
Cut with round bits arranged on dual drums. Since each dedicated bit rotates independently, no uneven wear of the bits will occur. Bits have excellent cost performance.
