Are you performing a roughing, medium, or finishing operation?
Our HMW turning catalogue presents, in a simple and intuitive way, the range of chipbreakers and grades dedicated to each specific ISO material group and operation.
We also offer “multi-purpose” grades that can be used for machining different materials.

We guarantee our customers the consistency of HMW insert quality over time, thanks also to the collaboration with certified and trusted suppliers for sintered blanks and coatings.
HMW turning inserts are available with CVD and PVD coatings, depending on the workpiece material and application, as well as uncoated for non-ferrous materials (aluminum, brass, copper, etc.).
CVD stands for Chemical Vapor Deposition, a process where the carbide substrate is coated through chemical reactions at temperatures ranging from 700 to 1050°C.
CVD coatings are characterized by high wear resistance and excellent adhesion to the carbide substrate.
However, they tend to round off the cutting edge and to increase the surface roughness of the insert.
PVD stands for Physical Vapor Deposition, a process where the coating is applied at relatively low temperatures (400-600°C).
PVD coatings enhance the toughness of the cutting edge while maintaining its sharpness, as well as improving wear resistance and preventing the edge chipping.
However, they are less wear-resistant compared to CVD coatings.
If the offered variety of geometries/chipbreakers/grades makes it difficult to decide, we are here to support you in choosing the best insert, optimizing your machining process and reducing costs.
For machining operations and materials that require high wear resistance and lower tendency to stick, we have introduced HMW positive Cermet inserts in our catalogue.
These inserts offer excellent performance for surface finishing operations with high-speed machining.
We offer two grades of Cermet:
For continuous or light interrupted cutting.
The PVD coating further enhances wear resistance.
Our HMW turning catalogue features a section entirely dedicated to HMW positive inserts for machining non-ferrous materials (aluminium, brass, lead, copper, etc.).
These inserts feature particularly sharp geometries and are available in two grades.
Uncoated grade for continuous or lightly interrupted cutting conditions.
Uncoated grade for interrupted cutting conditions.
