Diamond Core Bit.pdf

Description of Goods

Bits are attached to the foremost part of the Core barrels to be used in direct drilling of the ground, and play the most important role among the equipments that are used in drilling. There are many types of bits classified and used according to the purpose of drilling or ground conditions, and the bits are also different in their material, shape, and performance.

Turbo type diamond core bit is best suited to formations that are hard to very hard under conditions that are solid or at most slightly broken. The Turbo (Style T) waterway configuration is not recommended for use in highly fractured formations.

Due to the reduced face contact area, core bits with the Turbo (Style T) configuration will generally cut with less than a core bit of equivalent size and manufactured with the Regular (Style W) configuration and will usually do so with an equivalent or higher rate of penetration.

As a result, there is less of a tendency for the drill hole to deviate due to the application of lower bit loads. The partial (turbo) waterways also assist in ejecting the fine cuttings that are created when drilling hard, consolidated, non-abrasive formations and prevent the build-up of slurry on the bit face during drilling.
