Kexian Solid Carbide Drill Bits
Product Features:
Kexian solid carbide drill bits are engineered for precision and durability in demanding industrial applications. Crafted from premium-grade micrograin carbide substrates (0.4-0.6μm), these drills offer exceptional wear resistance and fracture toughness. Our proprietary AlTiN/TiAlN nano-multilayer coating (3-5μm thickness) enhances high-temperature stability, reducing friction and extending tool life by 3-5 times compared to conventional HSS drills.
The drills feature:
Four-Plane Point Geometry for self-centering capability, minimizing deflection and improving hole position accuracy (≤±0.02mm).
Parabolic Flute Design with variable helix angles (30°-40°) optimized for efficient chip evacuation, even in deep-hole applications up to 5xD.
Edge Honing Technology that strengthens cutting edges while maintaining sharpness, ensuring consistent hole quality (IT8-IT9 tolerance) and surface finish (Ra0.8-1.6μm).
Applications:
Ideal for machining a wide range of materials, including:
Alloy steels (up to 45 HRC)
Stainless steels (austenitic, ferritic grades)
Cast iron (GG/GGG)
Aluminum alloys (including high-silicon content)
Titanium alloys (with proper parameters)
Performance Advantages:
High-Speed Drilling Capability (up to 120 m/min cutting speed in steel)
Reduced Thrust Force design minimizes workpiece deformation
Optimized Core Thickness (15-20% increase) enhances drill rigidity
Through-Coolant Options available for deep-hole and difficult-to-machine materials
Quality Assurance:
Each drill bit undergoes rigorous QC testing, including:
Laser measurement of cutting edge geometry
Coating adhesion testing via scratch method
Actual drilling performance verification
Kexian solid carbide drills deliver precision, productivity, and cost-effectiveness, making them the preferred choice for automotive component manufacturing, aerospace parts production, mold & die making, and general engineering applications.
