T2139-R5-carbide finish ball mill insert

Description

T2139-R5-carbide finish ball mill insert is a precision carbide finishing insert developed for CNC finish milling, contouring, and 3D surface machining in medium to hardened materials. Designed for use in indexable finish ball mills, this insert delivers excellent surface finish, stable cutting performance, and consistent dimensional accuracy, making it ideal for die & mould machining, automotive components, aerospace parts, and precision engineering applications. The R5 ball radius ensures smooth profiling and uniform contact during finishing passes on curved and contoured surfaces.

Manufactured from high-quality carbide substrate, the T2139-R5 insert provides superior wear resistance, edge strength, and thermal stability, supporting reliable performance at high spindle speeds. Its optimized geometry reduces cutting forces and vibration, resulting in low chatter, improved surface integrity, and extended insert life. This allows machinists to achieve clean finishes while maintaining productivity and minimizing tool changes.

The insert is engineered for effective chip control and smooth cutting action, which helps reduce burr formation and often minimizes the need for secondary polishing. It performs well on commonly machined materials such as P20 steel, stainless steel, EN8/EN19, alloy steels, and other engineering materials used in moulds and precision components. The accurate seating in the cutter body ensures repeatable results across multiple inserts and production runs.

This product is commonly searched using keywords like finish ball mill insert, R5 ball nose insert, carbide milling inserts, CNC finishing insert, precision carbide tools India, CNC cutting tools manufacturers, and industrial cutting tools suppliers, aligning with strong buyer intent for high-quality finishing solutions. It is suitable for CNC vertical machining centers, high-speed milling machines, and multi-axis CNC systems where finish quality and reliability are critical.

The T2139-R5-carbide finish ball mill insert helps CNC shops improve surface finish consistency, reduce cycle time, and lower overall machining cost. By providing stable finishing performance and predictable tool life, it supports efficient production of mould cavities, fillets, complex contours, and precision surfaces in demanding CNC environments.
