Product Description

Product Description

Matrix(Customizable) 

Crown Height(Customizable)

Water outlets(Customizable)

Selected premium synthetic diamond and metal powder. Using a unique vacuum sintering technology, the sharpness and lifespan of the drill bit are significantly improved.

15mm standard crown height, (vs. 10-12mm industry average). Drill bit lifespan increased significantly Reduces bit replacement by 2-3 Reduce drill bit replacement frequency,Reduce labor and time costs and improve work efficiency.

Evenly spaced water outlets, curved flow channels (reduces water resistance). Improve drainage efficiency—effectively flushes cuttings, cools the matrix, and Significantly reduce the risk of overheating.
