Our Carbide drill bits
Carbide drill bits have wide versatility, high strength, high hardness performance, fast cutting speed, wear resistance, and good red hardness, and are suitable for processing parts of various materials. 
Solid carbide drill bit processing steps
1. Bar Selection
The manufacturing process begins with the careful selection of raw materials. High-quality cemented carbide round bars are typically used as blanks. These bars are made from tungsten carbide powder and a cobalt-based binder using powder metallurgy. Strict control over particle size, cobalt content, and density is crucial, as these characteristics directly determine the hardness, toughness, wear resistance, and service life of the final drill bit, laying a solid material foundation for producing high-performance drill bits.
2. CNC Grinding
This is the core step in giving the drill bit its precise geometry. The bar stock is clamped on a precision five-axis CNC grinding machine and ground using diamond grinding wheels according to a preset program. This process precisely shapes all critical parts of the drill bit, including the drill tip, cutting edge, chip flutes, and shank, in a single pass. CNC grinding ensures that each drill bit has a complex and precise geometry, including the point angle, helix angle, and cutting edge, which is crucial for achieving efficient cutting, smooth chip removal, and excellent hole quality.
3. Tool Inspection
After grinding, the drill bit must undergo rigorous and comprehensive inspection to ensure it meets design standards. Inspectors use high-magnification microscopes, projectors, and precision measuring instruments to meticulously check the drill bit's critical dimensions (diameter, cutting edge length), geometric angles, cutting edge quality, and surface finish. This step is central to quality control, aiming to eliminate any defective products with microscopic chipping, dimensional deviations, or shape defects, ensuring the reliability and consistency of the products leaving the factory.
4. Tool Coating
To significantly improve drill bit performance, an extremely thin (typically a few micrometers) superhard coating is applied to the rigorously inspected and cleaned drill bit surface using advanced processes such as chemical vapor deposition or physical vapor deposition. Common coating materials include titanium nitride and titanium aluminum nitride. This coating greatly improves the drill bit's surface hardness, heat resistance, and chemical stability, effectively reducing friction, wear, and heat accumulation during cutting, extending drill bit life several times over, and enabling higher-speed cutting operations.
5. Laser Marking
After coating, a permanent mark is clearly engraved on the drill bit shank using a laser marking machine. These marks typically include the brand logo, drill bit diameter, flute code, production batch number, and other important information. Laser marking is not only clear, wear-resistant, and durable, facilitating user identification and management, but also serves as a brand anti-counterfeiting and product traceability mechanism, making it an indispensable information-based step in the production process
6. Packaging
Finally, qualified drill bits are packaged according to specifications and order requirements. Each drill bit is usually individually protected with a dedicated plastic or foam sleeve and then placed in an elegant packaging box or tube. The packaging may include a product certificate and instructions for use. Proper packaging not only prevents damage during transportation and storage, ensuring the product is delivered to the customer in perfect condition, but also reflects the brand's professional image and commitment to the product.
