1. Premium Material & Design
Crafted from high-grade HSS Co alloy, our drill bits feature a precisely engineered composition with 5-8% cobalt content. This unique blend significantly boosts red hardness up to 650°C, ensuring the bits retain sharpness and structural integrity during high-speed operations. The fully ground flutes and optimized helix angles are designed for efficient chip evacuation, reducing heat generation and extending tool life.
2. Unmatched Performance Features
Superior Heat Resistance: Cobalt addition enhances thermal stability, preventing edge softening even under intense machining conditions. This makes our drill bits ideal for continuous heavy-duty drilling tasks.
Exceptional Wear Resistance: With a hardness of 64-67 HRC, these bits resist abrasive wear 3 times longer than standard HSS drills. The fine-grained microstructure ensures consistent performance through prolonged use.
High Toughness: Balancing hardness with excellent impact resistance, our HSS Co drill bits withstand high torque and sudden stress, reducing the risk of breakage when drilling hard or uneven materials.
3. Extensive Application Scenarios
Metals: Perfect for drilling stainless steel, alloy steel, cast iron, copper, aluminum, and heat-treated steels. Their heat resistance excels in machining nickel-based alloys and other tough metals.
Non-Metals: Effective on engineering plastics, fiber-reinforced composites, and hardwoods, delivering clean holes without material cracking or melting.
4. Precision Manufacturing Standards
Manufactured using advanced rolling and heat-treatment processes, each drill bit undergoes strict quality control. We ensure tight dimensional tolerances (±0.02mm) for accurate hole sizes and consistent performance. The polished surface finish minimizes friction, further improving chip removal and cutting efficiency.
5. Diverse Sizes & Custom Options
Available in a wide range of metric (from Φ0.5mm) and imperial (from 1/64") sizes, our HSS Co drill bits suit various drilling needs. Additionally, custom geometries, flute lengths, and special coatings (such as TiN or TiAlN) can be tailored to specific industrial requirements, ensuring maximum versatility and application flexibility.
