The concrete saw which thought cutting performance, durability and rust  resistance nature, and safety as important.
 A ductile cast iron( ERC14DB-18DSB) are adopted as each chassis , high-precision processing is added , raise in rigidity and low center of gravity are attained.
Therefore the stable operativity and excellent cutting capability are realized.

The centrifugal force radiation system by which cooling water spreads round the whole blade is used for a blade holder. The cooling effect is raised and performance of cutting and improvement in a blade life are aimed at.
It designs by the concept which can perform rise and fall of a blade, a run, and a stop by one operation handle. An operation handle is easily substitutable to a rise-and-fall axis and a run axis.Moreover, if a handle is inserted for reverse, it will utilize at the time of the stop at a slope. It can be operated by one handle, and it becomes possible to also enlarge an operation radius, the load of rise and fall and a run is reduced, and work is easy. It is striving for mitigation of an operation mistake with the big directions seal.
