CoroMill® 178
Solid carbide and PM-HSS power skiving tools for gear and spline production with high output
High productivity and flexibility
Possible to machine the complete component in a multi-task machine or machining center in a single set-up, which reduces the production time, improves quality and cuts handling and logistics costs.
Reduced cycle times
Considerably reduced machining cycle time compared to conventional machining methods such as broaching, shaping and hobbing.
Also efficient in dry machining
Power skiving also operates efficiently in dry conditions, which eliminates coolant costs and ensures environmentally- and operator-friendly machining.
Application area
- Internal and external gears and splines
- Cylindrical spur and helical gears

To order
Power skiving is available as an engineered solution. For more information, contact your local Sandvik Coromant representative.
Sandvik Coromant's solution includes the tooling, application support and a service offer with technical feasibility consultancy.
Chamfering and deburring tools to complement the power skiving tools are also available.
What is power skiving?
Power skiving is a continuous cutting process that enables all machining to be carried out in a single setup. In essence, it is a combination of hobbing and shaping. The intersecting angle between the tool and gear axis and the revolution speed are vital factors in productivity.
A further advantage of the machining method is its ability to machine close to shoulders, allowing greater freedom in component design.
