Internal Coolant Micro Drill

Key Features:
– Internal Coolant System: Precision-engineered coolant channels (through-tool design) enable direct delivery of cutting fluid to the drill tip, enhancing cooling and chip removal in deep-hole applications.
– Ultra-Fine Diameters: Available in sizes from **0.5mm to 3.0mm** (standard), with tolerances as tight as ±0.005mm for critical operations like fuel injector nozzles or surgical tool fabrication.
– Advanced Materials:
– Solid Carbide Construction: Exceptional hardness (up to 1800 HV) for drilling titanium, Inconel®, and ceramic-matrix composites.
– Cobalt-Enhanced HSS: For cost-effective machining of stainless steel and aluminum alloys.
– Optimized Geometry: Helical flutes and polished surfaces minimize friction and prevent chip clogging, even at high spindle speeds (up to 30,000 RPM).
– Specialized Coatings: Optional AlCrN (Aluminum Chromium Nitride) or diamond coatings enhance wear resistance and thermal stability in dry or semi-dry machining.

Applications:
– Aerospace: Drilling cooling holes in turbine blades, combustion chambers, and lightweight structural components.
– Medical Devices: Precision machining of bone screws, microfluidic devices, and implantable sensors.
– Automotive: High-speed production of fuel injectors, transmission valves, and EV battery components.
– Electronics: Micro-drilling in high-density PCBs and semiconductor packaging.
– Mold & Die Making: Creating cooling channels in injection molds and precision tooling.

Advantages:
– Extended Tool Life: Reduced thermal stress and wear via efficient coolant flow, lowering replacement costs.
– Superior Surface Finish: Minimized burring and heat-affected zones (HAZ) ensure high-quality hole walls.
– Increased Productivity: Faster feed rates and deeper drilling capabilities reduce cycle times.
– Versatility: Compatible with oil-based, water-soluble, or MQL (Minimum Quantity Lubrication) systems.

Technical Specifications:
– Material: Solid Carbide, HSS-Co (5%–8% Cobalt), or Carbide-Tipped.
– Coolant Channel Design: Single or dual channels (customizable for flow rate optimization).
– Diameter Range: 0.5mm–3.0mm (standard), custom sizes up to 5.0mm.
– Coating Options: AlCrN, TiSiN, Diamond, or Uncoated.
– Shank Type: Straight or cylindrical shank (ER collet compatibility).
– Compliance: Manufactured to ISO 13399 standards with full traceability and QA documentation.

Customization & Support:
– Tailored Solutions: Custom coolant channel configurations, coatings, or tip geometries (e.g., parabolic drills for chip clearance).
– Bulk Packaging: Vibration-resistant trays or reusable cases for industrial-scale users.
– Technical Support: On-demand machining parameter recommendations for specific materials.
