Product Detailed Description
The micro diameter drill bit is engineered for extreme precision in drilling tiny holes (typically 0.1mm-3mm in diameter), making it indispensable in industries where miniaturization and accuracy are critical. Crafted with high-grade tungsten carbide and enhanced with a wear-resistant TiAlN coating, this tool delivers consistent performance across diverse materials and demanding applications.
Key Application Scenarios
- Electronics Manufacturing: Perfect for drilling micro-vias and through-holes in PCBs (printed circuit boards), where even a 0.01mm deviation can ruin components. It handles FR4 laminates, copper-clad substrates, and flexible circuits with minimal burring, ensuring clean connections in smartphones, laptops, and wearable devices.
- Medical Device Production: Essential for machining tiny components like surgical needles, catheter ports, and implant parts. Its ultra-fine tip and stable cutting action prevent material deformation in stainless steel, titanium, and medical-grade plastics, meeting strict biocompatibility and dimensional standards.
- Aerospace & Defense: Drills precision holes in lightweight alloys (e.g., aluminum, titanium) for aerospace components like sensor housings, fuel line nozzles, and avionic connectors. Withstands high-speed rotation (up to 50,000 RPM) without vibration, critical for safety-critical parts.
- Jewelry & Micro-Machining: Creates intricate holes in precious metals (gold, platinum) and small metal parts (watch gears, micro fasteners), where detail and finish matter. Reduces material waste with accurate, burr-free results.
Core Advantages
- Unmatched Precision: Ground to tight tolerances (±0.002mm) with a sharp, centered tip, ensuring hole roundness and concentricity - vital for press-fit components and fluid/electrical pathways.
- Extended Tool Life: Tungsten carbide substrate resists chipping, while the TiAlN coating reduces friction and heat buildup. Lasts 3-5x longer than standard HSS micro drills, lowering replacement costs.
- Versatile Material Compatibility: Efficiently drills metals (steel, brass, alloys), plastics (PEEK, acrylic), and composites, eliminating the need for multiple tools in mixed-material production.
- Stable High-Speed Performance: Optimized flute design enhances chip evacuation, preventing clogging in deep micro holes (up to 10x diameter depth). Maintains balance at high RPMs, reducing tool breakage.
- Cost-Effective for Small-Batch & Mass Production: Reliable consistency minimizes rework, making it ideal for both prototyping (e.g., microfluidic chips) and high-volume runs (e.g., PCB fabrication).
