Multi-flute Micro Drills are high-performance precision tools engineered for rapid, efficient material removal and superior surface finishes in micro-scale drilling applications. Featuring multiple cutting edges (typically 2–4 flutes), these drills optimize chip evacuation, reduce cutting forces, and enhance stability, making them ideal for machining soft to medium-hard materials like aluminum, copper, plastics, and composites. Designed for industries prioritizing speed and precision, they are widely used in electronics, optics, and high-volume manufacturing.
Key Features:
– Multi-Flute Design: 2 to 4 flutes maximize cutting efficiency, enabling higher feed rates and smoother hole walls compared to single-flute drills.
– Ultra-Fine Precision: Diameters range from **0.2mm to 2.5mm** (standard) with tolerances as tight as ±0.005mm for applications like PCB via drilling or optical component fabrication.
– Advanced Materials
– Solid Carbide: Delivers exceptional rigidity and wear resistance for drilling ceramics, fiberglass, and carbon-fiber composites.
– High-Speed Steel (HSS): Cost-effective solution for non-ferrous metals and thermoplastics.
– Optimized Geometry: Polished flutes and sharp cutting edges minimize friction and prevent chip adhesion, critical for sticky or ductile materials.
– Specialized Coatings: Optional TiCN (Titanium Carbo-Nitride) or ZrN (Zirconium Nitride) coatings reduce heat buildup and extend tool life in high-speed operations.
Applications:
– Electronics Manufacturing: Drilling micro-vias in high-density PCBs, flex circuits, and LED substrates.
– Optics & Photonics: Precision holes in lenses, fiber-optic connectors, and laser components.
– Automotive: High-speed production of sensors, connectors, and lightweight alloy parts.
– Medical Devices: Machining biopsy needles, microfluidic channels, and implantable device components.
– Consumer Goods: Detailed work in watch mechanisms, jewelry, and miniature plastic parts.
Advantages:
– Increased Productivity: Multi-flute design allows faster feed rates, reducing cycle times in mass production.
– Superior Chip Control: Efficient chip evacuation prevents clogging and reduces heat-related tool wear.
