With a robust 4-flute design and a 30-degree cutting angle, it excels in both roughing and finishing tasks. The TiN finish enhances durability, while the innovative chipbreaker styles ensure efficient cutting and minimal chip buildup. ## Description The Sandvik Coromant SCMT H13A uncoated carbide indexable turning insert with a choice of KR and KM chipbreaker has a square shape with a 7-degree clearance angle, providing a balance of hardness and toughness for resistance to wear and shock for turning of aluminum in average machining conditions. The single-sided positive insert has chip grooves on one side, a countersunk hole in the center, and four 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 for roughing, facing, interrupted cuts, and large lead angles. This uncoated carbide grade combines hardness and toughness for resistance to wear and shock when turning aluminum in average conditions. The SCMT H13A is available with a choice of two types of chipbreakers: KR and KM. The KR chipbreaker style is designed for high cutting depths and feed rates when roughing aluminum. The KM chipbreaker style is designed for medium machining of aluminum. Tolerance of distance from the outer edge of the inscribed circle to the point of the square is + or - 0.002” to 0.005” and tolerance of the theoretical diameter of the insert is + or - 0.002” to 0.005”. 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 angle, tolerance, size, geometry, grade, and chipbreaker style.Sandvik Coromant produces tools for turning, milling, and drilling. Headquartered in Sweden and represented in 130 countries, the company manufactures tools used throughout the metalworking field, including the automotive and aerospace, die and mould, and general engineering industries. All Sandvik Coromant inserts meet ISO and ANSI standards.Matching Inserts to HoldersThese inserts are part of the Sandvik Coromant 107 Positive Insert family, which means they can be used in the CoroTurn 107 clamping system. The CoroTurn 107 system is used for internal longitudinal turning of small diameters, and is also for external light roughing to finishing. ## Features - Designed for turning operations – roughing to medium machining -- on aluminum in average machining conditions - H13A uncoated carbide grade provides a balance of hardness and toughness for resistance to wear and shock - Square shape offers edge strength and is suitable for roughing, facing, interrupted cuts, and large lead angles - Roughing (KR) and medium-machining (KM) chipbreaker styles help prevent chip buildup at a range of cutting depths and feed rates - Positive single-sided insert with 7-degree clearance angle for light cutting forces and side clearance ## Images ![Niagara Cutter N41120 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 4-Flute, 2.875" OAL, 0.375" Cut Diameter, 0.375" Shank Diameter - Image 1](https://m.media-amazon.com/images/I/61ScFpDrDtL.jpg) ![Niagara Cutter N41120 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 4-Flute, 2.875" OAL, 0.375" Cut Diameter, 0.375" Shank Diameter - Image 2](https://m.media-amazon.com/images/I/61aG6nG09HL.jpg) ![Niagara Cutter N41120 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 4-Flute, 2.875" OAL, 0.375" Cut Diameter, 0.375" Shank Diameter - Image 3](https://m.media-amazon.com/images/I/718lvJkbBoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Awersome *by M***L on Reviewed in the United States on November 21, 2015* This end mill has been bullet proof for me so far. Contact Niagara and they will send you a slide rule for figuring out speeds and feeds too. I now own about 25 Niagara cutters.
