STS STH65 12.0xD12x30x75

Description

STS STH65 12.0xD12x30x75 is a precision solid carbide end mill engineered for CNC machining of hardened materials up to 65 HRC. Designed for consistent performance and stability, this end mill is ideal for die & mould machining, automotive components, aerospace tooling, and precision engineering applications where dimensional accuracy and surface quality are critical. With a 12 mm cutting diameter, 30 mm flute length, and 75 mm overall length, it offers an optimal balance of rigidity and reach for semi-finishing and finishing operations in hardened steels.

Manufactured from premium micro-grain carbide rod, the STS STH65 series delivers strong edge integrity, wear resistance, and thermal stability, enabling dependable results during high-speed CNC milling. The tool performs effectively 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 cutting geometry reduces vibration and cutting forces, helping maintain tight tolerances and a smooth surface finish even in demanding machining conditions.

The D12 shank ensures secure clamping with low run-out, improving machining stability and minimizing chatter. The flute design supports efficient chip evacuation, reducing heat buildup and the risk of edge chipping during continuous cutting cycles. This makes the tool 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.
