This Sandvik Coromant CoroCut 1-Edge grooving insert is carbide GC2135 grade and has one cutting edge, a non-handed 0-degree cutting angle, and a GR chipbreaker for neutral-cut deep external grooving of stainless steel at high feed rates. GC2135 grade is carbide with a coating of titanium carbonitride (TiCN), aluminum oxide (Al2O3), and titanium nitride (TiN) applied through medium-temperature chemical vapor deposition (MTCVD) that provides toughness for shock resistance without limiting hardness for wear resistance in difficult-to-average machining conditions. MTCVD coatings are deposited at lower temperatures than CVD coatings to reduce cracks in the coating.
This single-edged insert has a GR chipbreaker, which has excellent chip control for deep grooving at high feed rates. It has a non-handed 0-degree cutting angle for a neutral cutting direction. The insert has a rail-shaped clamping groove on one side. The tolerance of the cutting width of the insert is + or - 0.003".
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 1-2, an indexable holding system for internal and external medium to deep parting, grooving, and profiling operations. The V- or rail-shape design of the toolholder provides secure clamping.
