Product Features

  • Designed for medium machining turning operations on cast iron in difficult to average machining conditions
  • GC3215 grade is an MTCVD coating of titanium carbonitride (TiCN), aluminum oxide (Al2O3) and titanium nitride (TiN) over carbide that provides shock resistance without limiting wear resistance
  • Triangle shape is used when there is limited machine power, a tendency toward vibration, or when either a large or small lead angle is required
  • Medium-machining (flat top) chipbreaker style prevents buildup of chips at a range of cutting depths and feed rates
  • Positive single-sided insert with 11-degree clearance angle for light cutting forces and side clearance

Product Description

The Sandvik Coromant TPU GC3215 indexable turning insert with flat top chipbreaker has a triangle shape with an 11-degree clearance angle, providing shock resistance without limiting wear resistance for medium machining cast iron in difficult to average machining conditions. This single-sided positive insert has a flat top and three cutting edges. It has an 11-degree clearance angle for light cutting forces and side clearance, making it better than a negative insert for internal turning. It can also be used when there is limited machine power, a tendency toward vibration, or when either a large or small lead angle is required. GC3215 grade is a combination of carbide and a coating of titanium carbonitride (TiCN), aluminum oxide (Al2O3) and titanium nitride (TiN) applied through medium temperature chemical vapor deposition (MTCVD), which has toughness for shock resistance without limiting wear resistance at low to medium speed turning, making this grade suitable for operations requiring demanding interrupted cuts. MTCVD coatings are deposited at lower temperatures than CVD coatings. The lower temperatures reduce cracks in the coating and provide increased toughness and smoothness without limiting wear resistance.

The TPU GC3215 has a flat top chipbreaker, for medium machining cutting depths and feed rates. Tolerance of the distance from the base to the tip of the triangle is + or - 0.005” to 0.012”. Tolerance of the theoretical diameter of the insert is + or - 0.005” to 0.010”. Insert thickness tolerance is + or - 0.005”. Different insert shapes and sizes may have different inscribed circle (iC) measurements, which are related to the insert’s range of cutting depths, speeds, lead angle, and feed rates. The inscribed circle is the largest circle that can be drawn within the edges of the insert shape. In general, as the insert size and iC become larger, the maximum cutting depth increases. The cutting depth influences the metal removal rate, number of cuts, chip evacuation, and power required 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, and grooving. They are held by an insert holder, have multiple cutting edges, and can be rotated when one edge wears down. Multiple inserts can be used to accomplish a variety of cuts in one operation. An insert is either positive or negative, which refers to the rake or clearance angle at which the insert removes material. Inserts are coded according to their specific cutting and application capability (e.g. VNMG 16 04 04-QM). Each part of the code represents details of the insert shape, nose angle, clearance, tolerance, size, geometry, grade, and chipbreaker style.

Sandvik Coromant manufactures tools for turning, milling, and drilling. The company, headquartered in Sweden, makes tools used throughout the metalworking field, including the automotive and aerospace, die and mold, and general engineering industries. Sandvik Coromant inserts meet International Organization for Standardization (ISO) and American National Standards Institute (ANSI) standards.

Matching Inserts to Holders

These inserts are part of the Sandvik Coromant CoroTurn 111 Positive Insert family, which means they can be used with CoroTurn 111 screw clamping system. The CoroTurn 111 is the first choice system for internal turning operations requiring light cutting forces.
