Diamond Core Bits of Turbo Type Wireline double and triple PQ HQ NQ BQ Exploration Diamond Core Drilling
Specifications:
Turbo Type Wireline double and triple PQ HQ NQ BQ Diamond Core Bits: hard to very hard formations under conditions
1. 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.
2. 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.
3. 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.
