Product Description

NTW HTW Thin Wall Turbo Type Double Tube Impregnated Diamond Core Bit




Cost reduction and efficiency improvement ; compared with the general drill bit ,further 20~50% footage can be realized in the same stratum.,


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.

  • In order to help the customer to select suitable bit and reduce customer’s workload, please follow below three steps to choice your bit.
