 The Sandvik Coromant TCMT GC1115 indexable turning insert with a choice of MM, UM, or MF chipbreaker style has a triangle shape with a 7-degree clearance angle, providing wear resistance for medium machining to finishing of stainless steel in average to good machining conditions. This single-sided positive insert has chip grooves on one side, a countersunk hole in the center, and three cutting edges. It has a 7-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. GC1115 grade is a combination of carbide and a coating of titanium aluminum nitride (TiAlN) and chromium oxide (Cr2O3) applied through physical vapor deposition (PVD), which provides hardness for high wear resistance at high temperatures without limiting shock resistance, making this grade suitable for finishing stainless steel at medium to low cutting speeds. Resistance to thermal shock makes this a good choice for light, interrupted cuts. PVD coatings give the insert longer life and better wear resistance than uncoated inserts, and maintain a sharper cutting edge than those with chemical vapor deposition (CVD) coatings.  The TCMT GC1125 is available with a choice of three types of chipbreakers: MM, UM, or MF. The MM and UM chipbreaker styles are for medium machining cutting depths and feed rates. The MM and UM chipbreakers have a higher range of cutting depths and feed rates than the MF chipbreaker. The MF chipbreaker is for finishing operations and generates low cutting forces, making this chipbreaker a good choice for thin-walled components. Tolerance of distance from the base to the tip of the triangle is + or - 0.002&#x201D; to 0.005&#x201D;. Tolerance of the theoretical diameter of the insert is + or - 0.002&#x201D; to 0.005&#x201D;. Insert thickness tolerance is + or - 0.005&#x201D;. Different insert shapes and sizes may have different inscribed circle (iC) measurements, which are related to the insert&#x2019;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 107 Positive Insert family, which means they can be used with CoroTurn 107 screw clamping system. The CoroTurn 107 is the first choice system for internal longitudinal turning of small diameters, and is also used for external light roughing to finishing of smaller, slender components.

## Features

- Designed for turning operations – from medium machining to finishing – on stainless steel in average to good machining conditions
- GC1125 grade is a PVD coating of titanium aluminum nitride (TiAlN) and chromium oxide (Cr2O3) over carbide that provides hardness for wear resistance without limiting shock resistance
- Triangle shape is suitable for light roughing and finishing, and 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 (MM, UM) and finishing (MF) chipbreaker styles reduce buildup of chips at a range of cutting depths and feeds
- Positive single-sided insert with 7-degree clearance angle for light cutting forces and side clearance
