Micro Drill 3.50xD4x18x50L

Description

Micro Drill 3.50xD4x18x50L is designed for ultra-precise drilling in miniature and high-accuracy applications. Made from premium solid carbide, these drills offer exceptional hardness, wear resistance, and cutting-edge sharpness for consistent performance. The 55 HRC grade makes them ideal for machining P20, SS304, sticky materials, and components with hardness between 38–45 HRC. Perfect for PCB drilling, watchmaking, jewelry, aerospace, electronics, and medical device manufacturing, these micro drills deliver clean, burr-free holes with tight tolerances.

Featuring precision-ground flutes for smooth chip evacuation, these carbide micro drills ensure minimal breakage and maximum tool life even at high speeds. Suitable for use in CNC machines, high-speed spindles, and precision drilling setups, they perform efficiently on steel, stainless steel, aluminum, brass, copper, and non-ferrous materials. Whether for tiny hole drilling in mold inserts or delicate assembly components, these micro carbide drills guarantee accuracy, reliability, and repeatable results.
