Micro drill bit crafted from ultra-hard 92% Tungsten Carbide (WC) with 8% Cobalt (Co) binder
Exceptional Hardness (HRA 89-95) – 3× longer life than HSS
Unmatched Wear Resistance - for stainless steel & hardened alloys
High-Temperature Stability - Maintains cutting edge at 800°C+
Precision-Ground Flutes - Optimized chip evacuation & reduced heat buildup
An uncoated (Bright) surface - reduces friction resistance during cutting
The 135-degree tip angle - provides excellent processing stability

√APPLICATION:
Tungsten carbide twist drill bits (1.75mm) excel in precision applications: PCB micro-drilling (0.15-3mm holes), device components, aerospace turbine cooling holes, maintaining micron-level accuracy in demanding industrial environments.
The drills are suitable for high-hardness metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.
