High-Precision U Drills for Aerospace & Manufacturing | Shandong Zhongren

We coat our U drills with advanced materials that provide a myriad of advantages. These coatings aid in friction reduction while drilling, causing a drop in the cutting temperature. This improved temperature extends the lifespan of the drill and enhances the surface quality of the holes that have been drilled. For instance, proprietary coating technology increases the U drill’s wear resistance by over 30%, improving the drill's capability for high-speed sustained drilling. Advanced surface finishes are critical for regions where the aesthetics of the parts post machining are vital. These industries rely not only on the precision of the drilled components but also the smoothness of their outer surface.

With our U drills, we have an innovative flute design that enhances chip removal. Their unique shape and geometry facilitate the removal of chips from the hole, mitigating chip congestion and lowering the risk of drill breakage and overheating. This flute design is especially advantageous for deep-hole drilling as it guarantees that cutting performance is maintained throughout the drilling process. Overall, this innovation allows for more efficient drilling and better quality holes.

Shandong Zhongren International Trade Co., Ltd. has been in business for more than 18 years in the CNC tool market. Such an enormous experience helps us understand the market together with their needs. We apply new techniques in producing our U drills and practice stringent quality control throughout the process. We have a global reach and over 50,000 cooperative customers which serves as a testament to the quality and dependability of our products.
