Improved surface finish: The design of TCMT432 helps achieve a high-quality surface finish on machined parts
TCMT 432 metal lathe tools are indexable carbide inserts designed for versatile turning operations. These inserts feature a 75° diamond shape with a 7° positive rake angle, suitable for medium to finish turning. They offer three cutting edges and a 40-60° countersink on one or two sides for secure tool holding. The TCMT 432 size indicates a 21.197mm cutting edge length, 9.525mm thickness, and a 12.7mm inner corner radius, providing a balance between strength and precision. These inserts are known for their ability to produce high-quality surfaces and are suitable for a range of materials including steel, stainless steel, and cast iron.
The TG4105 grade insert, featuring a yellow color and hardness levels ranging from P15 to P30, is enhanced with a CVD coating. This insert is crafted from a dual-structure alloy substrate that offers improved toughness. It is coated with a medium-thick layer of MT-TiCN and a thick layer of a-AI2O3, which provides excellent wear resistance and thermal stability. This insert is particularly recommended for general intermittent cutting applications involving carbon steel and low-alloy steel materials
The TG4245 grade insert features a dual-color design and offers hardness levels ranging from P25 to P40. It is constructed with a strong and tough alloy substrate, coated with a combination of MT-TiCN and a thick layer of a-AI2O3. This coating provides excellent edge strength and resistance to plastic deformation, making it the ideal choice for machining under unstable working conditions.
The TG4135 grade insert, with its black color and hardness ranging from P15 to P30, is equipped with a CVD coating. This insert is made from a dual-structure alloy substrate that enhances toughness. It is coated with both MT-TiCN and a thick layer of a-AI2O3, a combination that is further treated with stress balance technology. This treatment results in exceptional reliability and wear resistance, making it highly suitable for a broad spectrum of steel processing applications.
