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.
