The YG-1 EMI43915 is a high-performance, high-efficiency carbide end mill from the advanced i-Smart / i-Xmill series. Designed with a 5-flute geometry and a .030" corner radius, this tool is engineered for severe metalworking applications, offering high stability, reduced vibration, and superior surface finishes in high-speed machining (HSM).
Coated in AlTiN (Aluminum Titanium Nitride), it provides extreme oxidation resistance and hot hardness, making it ideal for dry or high-heat cutting of stainless steels, alloy steels, high-temp alloys, and pre-hardened steels.
i-Smart 5-Flute Design: Multi-flute configuration maximizes core strength and allows higher feed rates while suppressing chatter during aggressive profiling and trochoidal milling.
.030" Corner Radius: Fortifies the cutting corners to prevent chipping, substantially extending tool life under heavy chip loads.
AlTiN Coating: Delivers exceptional thermal protection and lubricity for dry machining or high-speed cutting in tough materials.
Variable Flute Geometry: Reduces vibration and harmonics for smoother cutting action and refined surface finishes.
Premium Micrograin Carbide: High-rigidity substrate engineered to withstand shock loading and abrasive wear.
