Micro Drill Bit: 2.9 mm Dia, 140 &deg MPN:06050

Manufactured from high-quality cobalt steel for exceptional wear resistance and durability, this micro drill bit has a diameter of just 2.9mm with cutting lengths under 1 making it ideal for precise, delicate applications. Its thin flutes allow easy entry into tight spaces while keeping the bit rigid during use, preventing deflection when working in hard-to-reach areas such as computerized mills or CNC machines' circuit boards, avionics wiring harnesses or precision machined parts with minimal clearance. With a high-performance two-cut helix design featuring 140 degrees angle per flute this bit evacuates chips efficiently maintaining chip load control thus increasing its longevity by minimizing heat build-up and reducing stress caused when cutting into hard metals such as stainless steel, titanium or inconel alloys typical of aviation components fabrication. In addition to its specialized function in electronics work and machining industry where holemaking is critical for quality and precision; it can also serve a broad range of DIY enthusiasts who need versatile bits capable to tackle metal drilling tasks efficiently while avoiding excessive clogging or breakage due to extreme material requirements.
