Secure, cost-efficient production of quality components is often the focus when selecting inserts and grades for parting and grooving. Whether you are parting-off small components or grooving large diameters, you will find your insert grade for parting and grooving here.
First-choice grade GC1225 is a thin-coated PVD grade to be used at medium to high cutting speeds. It is ideal for all parting, grooving and turning operations in good conditions. With GC1225 you get superior flank wear resistance and edge line toughness.

PVD-coated first-choice grade for all parting, grooving and turning operations in good conditions. The grade works well on low-carbon and other smearing materials. Superior flank wear resistance and edge line toughness at medium cutting speeds.
PVD-coated carbide grade with good adhesion and flank wear resistance. The combination of hard substrate and coating allows significant increases in cutting speed.
Excellent combination of high wear resistance and good edge security. To be used in grooving, turning and parting off operations under stable conditions at medium to high cutting speeds.
The safest grade choice for parting-off in fair to unstable conditions at low speeds. Works well when combined with High Precision Coolant (HPC) at medium speeds (reduced temperature).
Cubic boron nitride (CBN) composite grade for hardened ferrous materials and HRSA. Suitable for both continuous and interrupted cuts.
CVD-coated grade for tough and demanding operations such as parting-off to centre and interrupted cuts. Low to medium cutting speeds.
A titanium-based uncoated grade with excellent resistance to oxidation and smearing. For high-quality surface finishes when grooving low-alloyed steels under fairly good conditions. Moderate cutting speeds and feeds.
PVD-coated grade for parting off in stable conditions. Speeds and feeds from low to medium.
For long tool life in grooving applications in steel and cast iron. Suitable for parting off at stable conditions, especially in machines with oil coolant.
