T2139-R10 (STS) INSERT – 55 HRC finish ball mill insert

Description

T2139-R10 (STS) INSERT – 55 HRC finish ball mill insert engineered for CNC milling and finishing operations in medium to hardened materials up to 55 HRC. Designed for use in indexable finish ball mills, this insert delivers exceptional surface finish, stable cutting performance, and longer tool life in demanding machining environments. With its R10 ball radius, the insert provides smooth transitions and consistent contact when generating 3D contours, fillets, radii, and complex curved surfaces in CNC machining.

Manufactured with premium STS-grade carbide and optimized for 55 HRC machining, the T2139-R10 insert offers superior wear resistance, thermal stability, and cutting edge strength, making it ideal for die & mould finishing, automotive parts, aerospace components, and precision engineering applications. Its geometry minimizes cutting forces, reduces chatter, and enhances the tool life of the ball mill body it seats into.

The ball radius design enables improved surface integrity and reduced machining time on finishing passes. It is widely used on CNC vertical machining centers, high-speed spindles, and multi-axis milling machines where accuracy and finish quality are critical. Whether machining stainless steel, P20 steel, EN8/EN19, and alloy steels, the STS insert consistently delivers clean, burr-free surfaces with optimal dimensional accuracy.

This product is frequently searched under terms such as finish ball mill insert, R10 ball nose insert, carbide milling inserts, CNC finishing cutters, precision carbide tools India, industrial cutting tools suppliers, and CNC cutting tools manufacturers. Such keywords align with high buyer intent from industrial cutting tools suppliers, precision tooling houses, and CNC tools supplier in India looking for reliable finish milling components.

The T2139-R10 (STS) INSERT helps reduce manual polishing, improve repeatability in production runs, and achieve superior finishes on mould cavities, aerospace profiles, and automotive trim features. Its robust carbide composition and optimized design support stable machining at higher feed rates with lower tool pressure, improving cycle time and reducing machining cost.

Overall, this finish ball mill insert is a dependable choice for precision CNC machining where consistent surface finish, dimensional accuracy, and extended insert life are essential for productivity and quality.
