STS STU65 12.0xD12x45x100

Description

STS STU65 12.0xD12x45x100 is a high-performance solid carbide end mill designed for CNC machining of hardened materials up to 65 HRC. Engineered for reliability and consistent results, this end mill is ideal for die & mould machining, automotive components, aerospace tooling, and precision engineering applications where stable cutting and predictable tool life are essential. With a 12 mm cutting diameter, 45 mm flute length, and 100 mm overall length, it offers excellent reach and rigidity for both semi-finishing and finishing operations.

Manufactured from premium micro-grain carbide rod, the STS STU65 end mill provides strong edge toughness, wear resistance, and thermal stability, enabling dependable performance during high-speed CNC milling. It is suitable for machining D2 steel, hardened P20, tool steel, and high-hardness alloy steels in the 55–65 HRC range, which are commonly used in mould and die manufacturing. The cutting geometry is optimized to reduce vibration, maintain dimensional accuracy, and deliver a smooth surface finish even in challenging hardened materials.

The D12 shank ensures secure clamping with low run-out, improving machining stability and surface quality. Its flute design supports efficient chip evacuation, helping to minimize edge chipping and heat buildup during prolonged cutting cycles. This makes the tool suitable for a wide range of operations including profile milling, slotting, pocket milling, and contour machining on CNC vertical machining centers and high-speed milling machines.
