Solid Carbide Spot Drill Bit

1. Q: What are the main functions and applicable scenarios of this 90-degree point drill?
A: This hard alloy point drill integrates center drill, point drill and 90-degree chamfering functions. Its precise 90-degree angle design is specifically designed for accurately locating the center of the hole, creating guiding holes, and processing high-precision chamfers before turning or milling operations. It is a key tool for achieving efficient and accurate hole processing preparations.
2. Q: What does the term "HRC45 hardness" mentioned in the product description mean?
A: HRC45 indicates that the hardness of the tool body reaches 45 degrees on the Rockwell hardness scale. For hard alloy tools, a high base hardness is the fundamental guarantee for wear resistance and service life. This ensures that the point drill can resist wear during continuous processing, maintain dimensional stability and sharpness, and achieve long-term high-performance machining.
3. Q: How does "five-axis grinding machine processing" specifically enhance the performance of the cutting tools?
A: The five-axis grinding machine process achieves ultra-high precision for the edge formation and the grinding of complex geometric structures. This directly results in sharper cutting edges, thereby achieving smoother cutting surfaces and lower cutting resistance. At the same time, the unparalleled precision ensures the consistency and repeatability of each tool angle.
4. Q: How does the "large core diameter design" of the cutting tool ensure both rigidity and chip removal space?
A: We have achieved a large core diameter between the double-edge grooves through optimized design. This structure significantly enhances the overall rigidity and anti-vibration performance of the cutting tool, reduces the risk of fracture, and at the same time provides a smooth chip removal channel, effectively avoiding the common chip blockage problem that occurs during deep hole drilling.
5. Q: Compared to ordinary high-speed steel or cheap carbide point drills, where does this product's core advantage lie?
A: The core advantage lies in the combination of "high-performance carbide material" and "precise five-axis grinding process". This brings: 1) Longer service life and better wear resistance; 2) Higher processing accuracy and consistency of chamfers; 3) Stronger rigidity and reliability, reducing the risk of breakage; 4) Better chip removal and surface finish. It is a high-end tool designed for professional users who pursue efficiency, accuracy, and long-term cost-effectiveness.
