STS STH65 8.0xD8x35x100

Description

STS STH65 8.0xD8x35x100 is a high-performance solid carbide end mill designed for CNC machining of hardened materials up to 65 HRC. Engineered for precision and stability, this end mill is widely used in die & mould machining, automotive components, aerospace tooling, and precision engineering applications where surface finish, dimensional accuracy, and tool life are critical. With an 8 mm cutting diameter, 35 mm flute length, and 100 mm overall length, it provides extended reach while maintaining rigidity—ideal for deep cavities, profiles, and finishing operations in hardened steels.

Manufactured from premium micro-grain carbide rod, the STS STH65 series delivers excellent edge strength, wear resistance, and thermal stability, enabling consistent performance during high-speed CNC milling. The tool performs reliably on D2 tool steel, hardened P20, alloy steels, and other materials in the 55–65 HRC range commonly used in mould and die manufacturing. Its optimized cutting geometry minimizes vibration and cutting forces, supporting tight tolerances and superior surface quality even in demanding machining conditions.

The D8 shank ensures secure clamping with low run-out, enhancing machining stability and reducing chatter during long-reach operations. The flute design promotes efficient chip evacuation, limiting heat buildup and reducing the risk of edge chipping during continuous cutting cycles. This makes the end mill suitable for a wide range of CNC operations including profile milling, pocketing, slotting, and contour machining on vertical machining centers and high-speed milling machines.

This product aligns strongly with commonly searched terms such as 65 HRC carbide end mill, carbide end mill tools, CNC cutting tools manufacturers, high performance end mills, precision carbide tools India, die and mould machining tools, best carbide end mill for D2 steel, and CNC tools supplier in India, helping strengthen WordPress SEO performance and online visibility for industrial buyers.

The STS STH65 8.0xD8x35x100 is a dependable choice for CNC workshops seeking a cost-effective yet reliable hardened steel end mill. It is particularly suitable for regular production work, mould components, and precision parts, where consistent cutting behavior, controlled wear, and predictable results are essential for productivity and quality.
