Used with the Sandvik Coromant CoroCut 3 for straight, shallow external grooving in all materials
GC1125 grade is a physical vapor deposition (PVD) coating of titanium aluminum nitride (TiAlN) and chromium oxide (Cr2O3) over carbide that provides a balance of resistance to shock and wear in average machining conditions
GS chipbreaker with a sharp cutting edge for straight cutting at low feed rates
Screw clamp holding system allows insert to be indexed without being removed from the toolholder
Three cutting edges for indexing and a left-hand neutral cutting angle
This Sandvik Coromant CoroCut 3 indexable grooving insert is carbide GC1125 grade and has three cutting edges, a left-hand neutral cutting angle, and a GS chipbreaker for straight, shallow external grooving of all materials at low feed rates. GC1125 grade is a physical vapor deposition (PVD) coating of titanium aluminum nitride (TiAlN) and chromium oxide (Cr2O3) over carbide that provides a balance of hardness for wear resistance and toughness for shock resistance in average machining conditions. The PVD coating maintains a sharper cutting edge than a chemical vapor deposition (CVD) coating.
The insert has a GS chipbreaker, which has a sharp cutting edge for straight cuts at low feed rates. This three-edge, left-hand insert has a hole in the center for clamping to the toolholder with a screw, which allows the insert to be indexed without being removed from the toolholder. Tolerance of the cutting width of the insert is + or - 0.0008".
Grooving inserts are coded according to their specific cutting and application capability (e.g., N123M1-0900-0008-GM). Each section of the code represents details of the insert: hand, compatible toolholder series, seat size, number of edges, insert width, lead angle, corner radius, and chipbreaker. Generally, as the insert size becomes larger, the maximum cutting depth increases. Cutting depth influences the material removal rate, the number of cuts, and chip evacuation efficiency when using the insert. Indexable inserts are small cutting tools designed to remove material in external and internal cutting applications such as turning, milling, drilling, parting, and grooving. They are held by an insert holder and usually have multiple cutting edges that can be rotated when one edge wears down. Multiple inserts can accomplish a variety of cuts in one operation.
Sandvik Coromant produces tools for turning, milling, and drilling. Headquartered in Sweden, the company manufactures tools used throughout the metalworking field, including the automotive and aerospace, die and mold, and general engineering industries.
Matching Inserts to Holders
These inserts are used with the Sandvik Coromant CoroCut 3, an indexable holding system for external shallow parting, grooving, and profiling operations. The screw design of the toolholder provides secure clamping.
