STS STU65 10.0xD10x40x100

Description

STS STU65 10.0xD10x40x100 is a high-performance solid carbide end mill designed for CNC machining of hardened materials up to 65 HRC. Engineered for accuracy, rigidity, and dependable tool life, this end mill is ideal for die & mould machining, automotive components, aerospace tooling, and precision engineering applications where deep reach and stable cutting are essential. With a 10 mm cutting diameter, 40 mm flute length, and 100 mm overall length, it provides extended reach for deep pockets, cavities, and contour finishing while maintaining excellent rigidity.

Manufactured from premium micro-grain carbide rod, the STS STU65 series delivers strong edge integrity, 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 production. Its optimized geometry minimizes vibration and cutting forces, helping maintain tight tolerances and superior surface finish even in long-reach machining conditions.

The D10 shank ensures secure clamping with low run-out, improving machining stability and reducing chatter during extended cutting operations. Efficient flute design supports smooth chip evacuation, limiting heat buildup and reducing the risk of edge chipping during continuous machining. This makes the tool suitable for a wide range of CNC operations including profile milling, pocket milling, 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 STU65 10.0xD10x40x100 is a dependable choice for CNC workshops seeking a cost-effective yet reliable hardened steel end mill. It is particularly suitable for deep mould components, precision cavities, and production machining, where consistent cutting behavior, controlled wear, and predictable results are essential for productivity and quality.
