What is the application effect of Good Drilling Teeth on construction site?

What is the application effect of Good Drilling Teeth on construction site? Good drilling teeth have the features of high drilling efficiency, good wear resistance, and durability. This video shows the actual application of our bullet teeth drill bits on the construction site: the rock coring effect is very good, and after continuous operation, the wear degree of the drill teeth is low, and the integrity of the alloy head is good, too. This also proves that high wear-resisting, durability, and high piling efficiency are the criteria for judging good drilling teeth.
