The D1×50-4F HRC55 carbide endmill with AlTiN coating is a micro-size tool designed for ultra-precise CNC machining. With a 1 mm cutting diameter, an overall length of 50 mm, and a 4 mm reinforced shank, this tool combines fine detail machining capability with strong stability. The 4-flute geometry ensures smooth cutting, controlled chip evacuation, and a fine surface finish, even on delicate operations.
Made from ultra-fine grain solid carbide and hardened to HRC55, the tool provides superior toughness, accuracy, and extended service life. The AlTiN (Aluminum Titanium Nitride) coating further enhances durability by reducing friction, improving thermal resistance, and protecting against premature wear. Moreover, it enables reliable performance in both high-speed and dry machining conditions.
The D1×50-4F HRC55 carbide endmill is ideal for micro-slotting, precision profiling, engraving, and other fine applications. It is widely used in industries such as electronics, mold manufacturing, watchmaking, aerospace, and medical device production. Thanks to its rigid shank and optimized geometry, the tool minimizes vibration and guarantees repeatable accuracy even in hard steels, stainless steels, and alloys up to 55 HRC.
