Solid Carbide Drills

Key Features:
1. Full Carbide Construction：
– Material: High-density tungsten carbide substrate with optimized cobalt content (6–12%) for balanced hardness and fracture resistance.
– Hardness: 1,500–2,000 HV (Vickers) for prolonged edge retention in abrasive or hardened materials.

2. Advanced Geometry
– Point Angles: 118°–140° (standard) or custom angles for specific materials (e.g., 90° for sheet metal, 135° for stainless steel).
– Helix Angles: 30°–40° (high-helix for efficient chip evacuation in deep holes; low-helix for stability in hard materials).
– Flute Design: 2–4 flutes with polished surfaces to reduce friction and prevent chip clogging.

3. Coating Technology
– PVD Coatings: TiAlN, AlTiN, or TiSiN (3–5 µm) for enhanced heat resistance (up to 1,000°C) and reduced built-up edge (BUE).
– Nano-Coatings: Multilayer coatings (e.g., AlCrN) for extreme wear resistance in composites or hardened steels (45–65 HRC).

4. Coolant Capabilities
– Internal Coolant Channels: Precision-drilled holes for efficient coolant delivery to the cutting edge, reducing heat and extending tool life.
– Through-Tool Coolant: Optimal chip evacuation in deep-hole drilling (up to 10× diameter depth).

5. Versatile Applications
– Materials: Steel, stainless steel, aluminum, titanium, Inconel, composites, plastics, and hardened steels.
– Operations: Standard drilling, deep-hole drilling, step drilling, and micro-drilling (down to Ø0.3 mm).

Benefits：
– High Precision: Achieve tight tolerances (H7–H9) and superior hole surface finish (Ra ≤ 1.6 µm).
– Extended Tool Life: Carbide substrate and coatings resist wear, reducing tool changes and downtime.
– Increased Productivity: High-speed capability (up to 150 m/min in aluminum) and aggressive feed rates.
– Reduced Deflection: Solid carbide structure minimizes vibration for straighter holes in deep drilling.
– Cost Efficiency: Longer lifespan and consistent performance lower per-hole machining costs.

Available Configurations:
– Diameter Range: Ø0.3–25 mm (micro-drills to large-diameter tools).
– Shank Types: Straight shank, Weldon flat, or cylindrical shank (HSK, BT, or CAT compatible).
– Length Options:
– Standard: 3×D, 5×D. – Extended Reach: 8×D, 10×D (with reinforced core for deep-hole stability).
– Specialized Designs:
– Spot Drills: Combined drilling and chamfering in one operation.
– Step Drills: Multi-diameter holes for countersinking or deburring.
– Micro-Drills: Precision-ground tips for PCB drilling or medical components.

Quality Assurance:
– Precision Grinding: CNC-ground edges and flutes ensure concentricity ≤ 0.005 mm.
– Dynamic Balancing: G2.5 or higher for vibration-free performance at high RPM.
– Certifications: ISO 9001 compliance with full traceability of materials and processes.
Packaging & Logistics
– Protective Packaging: Individually wrapped in anti-corrosion foam or shock-resistant tubes.
– Bulk Orders: Customizable kits with drill cases for organized storage.
– Lead Time: Standard sizes in stock; custom tools in 3-6 weeks.

Industry Applications:
– Aerospace: Fuel nozzle holes, turbine blade cooling channels, CFRP composites.
– Automotive: Engine block oil passages, aluminum cylinder heads, EV battery housings.
– Medical: Surgical instrument holes, bone screw pilot drilling, micro-implants.
– Electronics: Precision PCB via drilling, connector components.

Solid Carbide Drills combine cutting-edge technology with robust design to tackle the most challenging drilling tasks. Whether machining exotic alloys, deep cavities, or micro-features, these tools deliver unmatched accuracy, speed, and reliability.
