Excavator Saws

Excavator Saws have a wide application in

Applications

They allow for precision cutting through a variety of materials.

Excavator saws produce a neat cut, with minimal damage and destruction. Apart from being a highly efficient method of material removal, they can also assist with reducing the need for other materials such as concrete in footings.

Excavator saws are

than other methods of rock and concrete removal.

Types of Excavator Rocksaw

Echidna designs and builds three types of excavator saws, each with their advantages for particular applications.

Very briefly,

Tungsten carbide

The most robust technology for excavator rocksawing, for materials such as soft stone and lightly reinforced concrete. Easy onsite tip replacement and no need for cooling water gives tungsten-carbide an advantage in quarries and remote locations. Low tip speed means greater safety on-site than with fast spinning blades

Diamond saws

Excavator diamond rocksaws are the most versatile  choice, offering a solution for the widest variety of materials. With our high quality diamond blades they cut medium to hard rock and reinforced concrete. Replace the blade to cut metals, wood and plastic.
