Uncoated Carbide Micro Drills are precision cutting tools crafted from premium tungsten carbide (WC-Co), designed for applications requiring raw material performance without the interference of coatings. Ideal for high-temperature environments, custom post-processing, or specialized machining tasks, these drills deliver exceptional hardness, rigidity, and versatility. Their uncoated surface ensures compatibility with secondary treatments like grinding, polishing, or custom coatings, making them a flexible choice for industries prioritizing adaptability and cost-efficiency.
Key Features:
– Pure Carbide Performance: Made from high-grade tungsten carbide with cobalt binder (6%–10% Co), offering a hardness of 1500–1800 HV** for drilling hardened steels, ceramics, and composites.
– Uncoated Surface: Raw carbide surface allows for easy regrinding, custom edge preparation, or application of user-specific coatings (e.g., TiN, AlCrN).
– Ultra-Fine Precision**: Diameters ranging from **0.1mm to 3.0mm** (standard) with tight tolerances (±0.005mm) for micro-hole drilling in electronics, optics, and medical devices.
– High-Temperature Resilience**: Maintains structural integrity in dry or high-heat machining conditions (up to 800°C), where coated tools may degrade.
– Optimized Geometry**: Sharp cutting edges and polished flutes ensure efficient chip evacuation and reduced friction, even in brittle or abrasive materials.
Applications:
– Electronics Manufacturing: Drilling micro-vias in PCBs, ceramic substrates, and semiconductor packages.
– Medical Device Fabrication: Precision holes in surgical tools, dental implants, and biocompatible alloys.
– Aerospace: Machining cooling holes in turbine blades, heat-resistant alloys, and composite materials.
– Mold & Die Making: Creating intricate cooling channels or ejector pin holes in hardened steel molds.
– Research & Prototyping: Ideal for experimental materials or processes requiring tool customization.
Advantages:
– Cost-Effective: Eliminates coating costs, ideal for applications where coatings offer no added benefit.
– Customization Flexibility: Easily reground or coated post-purchase to suit evolving production needs.
– Consistent Performance: Unaffected by coating delamination, ensuring reliable results in extreme conditions.
– Broad Compatibility: Suitable for wet or dry machining, MQL (Minimum Quantity Lubrication), or high-speed CNC operations.
Technical Specifications:
– Material: Tungsten Carbide-Cobalt (WC-Co).
– Diameter Range: 0.1mm–3.0mm (standard); custom sizes up to 5.0mm available.
– Flute Design: 2-flute (standard), 3-flute (optimized chip clearance), or custom configurations.
– Shank Type: Straight shank (metric or imperial) or cylindrical shank (ER collet compatible).
– Surface Finish: Ra ≤ 0.1μm (as-ground), customizable upon request.
– Compliance: ISO 9001-certified production with full traceability and hardness testing.
