XIAN TYDRILLBITS.CO.LTD

Xi'an Tydrillbits Co.,Ltd is one of the most famous China tsp core bit manufacturers, welcome to wholesale cheap pdc core bit from our factory. Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.
