In the manufacturing industry, many Chinese experts are dedicated to researching cost and efficiency performance, facilitating human technology. Regarding the future, Professor Hu believes, “one day globally renowned high-tech companies like Boeing or Tesla will also use Crown Drills, making even greater contributions to human.”

Due to the precise design of parameters, Crown Drills avoid the issue of iron chip entanglement. With smooth chip breaking and effective chip evacuation, the aluminum alloy drilling process maintains surface roughness within Ra 1.6~0.8. Additionally, a 40% reduction in axial force, a 30% decrease in torque, a 50% increase in processing efficiency, and over a two-fold increase in tool life signify an upgraded performance for Crown Drills. Practices show that it can drill up to 80 meters in stainless steel 316L (drill diameter 16, hole depth 50, speed 1600r/min, feed 200mm/min) and achieve 70 meters in P20 mold steel (drill diameter 16, hole depth 50, speed 1400r/min, feed 280mm/min), demonstrating good performance in titanium alloy and high-temperature alloy hole machining. As a self-developed drill, Crown Drill meets the demands of modern drilling processes for efficiency, precision, and durability.
“We dare customers to try it because those who have tried Crown Drills find it prone to be impressed by cost-performance. We confidently offer a no-questions-asked 7-day return policy because the likelihood of customer dissatisfaction is low, and even if they are dissatisfied, it informs us on how to further improve. We customize application solutions for customers because we take responsibility for the application results, rather than delivery only,” explained Professor Hu, regarding Zhongke Golden-drill’s service.

In the future, with the continuous improvement of domestic cutting tools, there is reason to believe that Crown Drills and Zhongke Golden-drill will showcase more brilliance on the world stage.
As Professor Hu states, “I have always admired inventors like James Watt, Tomas Edison, and Ni Zhifu who contributed to human technology. Drills are small, just a tiny part in manufacturing, but their impact is considerable. I hope Zhongke Golden-drill, like the small Crown Drill, dedicates a lifetime to improve efficiency slightly, then to create a bit more value for manufacturing, and then to make one small step for mankind.”
