High performance brazed diamond drill bit for efficient and wear-resistant precision drilling

Our brazed diamond drill bits have significant technical advantages: using advanced high-temperature brazing technology, high-grade diamond particles are firmly welded to the surface of the drill bit substrate, with a bonding strength that is more than three times higher than traditional sintering processes, effectively avoiding diamond detachment. The cutting edge of the drill bit is sharp and the exposed height of diamond particles reaches 60% -70%. It can quickly cut into hard materials such as stone, concrete, and metal, and the drilling efficiency is increased by more than 50% compared to ordinary drill bits. The unique brazing layer design enhances the impact resistance of the drill bit, making it less prone to chipping when drilling high hardness materials, and extending its service life to 2-3 times that of traditional drill bits. In addition, the diamond particles on the surface of the drill bit are evenly distributed, which can achieve high-precision drilling, smooth and fla

Its long-lasting characteristics can reduce replacement frequency and lower usage costs, while excellent drilling accuracy can save customers subsequent processing time. Choosing DeYi brazed diamond drill bits ensures both quality and efficiency, pr

What materials can I use diamond brazed drill bits on?

What is the difference between Beijing Deyi brazed diamond drill bits and traditional sintered drill bits? ​

The core differences between our brazed diamond drill bits and traditional sintered drill bits are reflected in three aspects: Process principle: The brazing process uses high-temperature molten brazing materials (such as copper based and nickel based alloys) to weld diamond particles onto the substrate, forming a metallurgical bond between the diamond and the substrate; The sintered drill bit is sintered by powder pressing, and the diamond is mechanically embedded and combined with the matrix. ​ Performance advantages: The diamond exposure height of brazed drill bits is higher, the cutting edge is sharper, and the drilling speed is faster; Combined with higher strength, diamond is less prone to detachment and significantly improves wear resistance, especially suitable for continuous operation of high hardness materials. ​

Customer's Real Use Evaluation of De Yi Brazed Diamond Drill Bit

Many industry customers highly recognize our brazed diamond drill bits: A stone processing enterprise feedback: "When processing high hardness granite, traditional drill bits need to be replaced 2-3 times per hour, while DeYi's brazed drill bits maintain good performance even after working continuously for 8 hours, and the drilling efficiency is nearly doubled, saving more than 200000 yuan in consumables costs every year." The construction engineering company stated: "In concrete wall drilling operations, this drill bit has excellent impact resistance, and even when encountering steel bars, it is not easy to break the edge. The drilling accuracy is high, greatly reducing rework rate and significantly improving construction efficiency." The metal processing workshop evaluation: "When used for high-precision drilling of cast iron parts, the wear resistance and stability of the drill bit are satisfactory, and the roughness of the hole wall is low. No need for secondary polishing, the prod
