This Sandvik Coromant T-Max Q-Cut 151.2 grooving insert is carbide GC1125 grade and has one cutting edge, a non-handed neutral cutting angle, and a 5G chipbreaker for grooving operations on all materials at medium feeds. 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 5G chipbreaker for general-purpose external or internal grooving at medium feed rates. This single-edged, non-handed insert has a neutral cutting angle and a groove for clamping. Tolerance of the cutting width of the insert is + or - 0.002" for the 151.2-A-5G code inserts and + 0.004 to - 0.000" for all others.
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 T-Max Q-Cut, an indexable holding system for internal and external grooving and parting operations. The spring or screw design of the toolholder provides secure clamping.
