Between the two types of roadheader cutterheads, the ripping (transverse) and the milling (in line or axial) heads, the ripping type is more suitable for hard rock cutting. This is due to more efficient cutting during sumping, due to resultant forces acting along the boom (and not perpendicular), better use

Cutting Tools Roadheader cutting heads laced with tungsten carbide tipped point attack bits have evolved into the state of the art in impact rock breakage for boom type mechanical excavators. However, high silica rocks limit their application for hard rock cutting due to the heat generated at impact and its effect on carbide. The cobalt content

The universal shield-mounted boom can be fitted with different cutting tools from a shovel, a ripper tooth or a hydraulic jackhammer, and a roadheader boom can be fitted for when rock of 80 MPa or more is encountered. The excavated material is transported by belt or chain conveyors to the conveying system located at the rear of the operation.

The roadheader does require a greater investment than an excavator with a roadheader attachment. The excavator's performance, however, is limited because it is dependent on the hydraulic power capabilities of the excavator. Attachments are extremely flexible in large tunnels for scaling, cutting manholes, corners and excessive grouting.
