D4×50-4F HRC55 Carbide Endmill with AlTiN Coating

The D4×50-4F HRC55 carbide endmill with AlTiN coating is a precision tool designed for detailed CNC machining. With a 4 mm cutting diameter, 50 mm overall length, and a 4 mm shank, it combines accuracy with rigidity. The 4-flute geometry ensures balanced cutting action, smooth performance, and reliable chip evacuation. This makes the tool suitable for slotting, profiling, and finishing operations.

Manufactured from fine-grain solid carbide and hardened to HRC55, the tool offers strength, toughness, and long tool life. The AlTiN (Aluminum Titanium Nitride) coating enhances heat resistance, reduces friction, and provides superior wear protection. As a result, it performs efficiently in steels up to 55 HRC, stainless steels, cast irons, and non-ferrous alloys.

Thanks to its robust shank design, the D4×50-4F HRC55 endmill minimizes vibration and ensures high precision. It is widely used in mold making, automotive, aerospace, and general engineering, delivering consistent accuracy and fine surface finishes.
