Product Introduction
Drill Bits , also known as mining drill bits, are the core consumable components of the mining drilling system. They are installed at the end of the drill pipe or the sub-bit, and are directly responsible for breaking the rocks. Their performance determines the drilling efficiency, hole quality, and mining cost.
Top-Hammer Bits
Structure: Threaded connection, carbide teeth embedded, compatible with top-hammer rock drills.
Features: High impact toughness, smooth slag discharge, suitable for medium-hard to hard rocks (such as granite, iron ore).
Common models: R thread, T thread, diameter 32–152mm.
DTH Bits
Structure: Compatible with percussive drills, column teeth / ball teeth design, high-pressure air for slag discharge.
Features: High drilling speed, stable deep hole performance, suitable for blasting holes in open-pit mines and water wells.
Common models: COP, QL, Mission series, with diameters ranging from 90 to 254mm.
PDC drill bit
Structure: Blade-wing type, embedded PDC composite blades, without moving parts.
Features: High wear resistance, long service life, low vibration. Suitable for soft to medium-hard rocks (coal, shale, sandstone).
Common models: Steel body / Tire body, diameter 75–445mm.
Tricone Bits
Structure: 3 rotatable truediameter wheels, with hard alloy teeth, and bearing sealing design.
Features: Suitable for extremely hard rocks and high-grinding strata, commonly used in open-pit mines / exploration.
Common models: IADC 412–825, with diameters ranging from 152 to 445mm.
Diamond Core Bits
Structure: The casing is embedded with natural / artificial diamonds, with circular cutting to obtain core samples.
Features: High-precision core extraction, stable for hard rocks, core tool for geological exploration / mineral assessment.
Common models: NQ, HQ, PQ, with diameters ranging from 46mm to 146mm.
Key Technologies and Materials
◆ Hard Alloy Teeth: High hardness (HRA 89–92), high toughness, impact-resistant and wear-resistant, suitable for crushing / hard rock.
◆ PDC Composite Blades: Diamond layer + hard alloy substrate, hardness up to HRC85+, good thermal stability, drilling efficiency increased by 30%+.
◆ High-strength Alloy Body: Forged / heat-treated, tensile strength ≥ 1200 MPa, resistant to deformation and fracture.
◆ Fluid Dynamics Design: Optimized water holes / slag discharge channels, rapid slag discharge under high pressure air / water, reducing repeated crushing, improving drilling speed.
◆ Sealing and Lubrication: Metal sealing + high-temperature lubricating grease, bearing life extended by 50%, suitable for high drilling pressure / high rotational speed conditions.
Typical Application Scenarios
◆ Open-pit Mining: Blasting hole drilling (tongwheel / submersible drill bits), slope anchoring (top hammer drill bits).
◆ Underground Mines: Tunnel excavation (PDC / top hammer drill bits), gas extraction / water exploration holes (directional PDC drill bits).
◆ Geological Exploration: Mineral prospecting / detailed exploration (diamond core drill bits), hydrogeological drilling.
◆ Special Engineering: Tunnel advance support, well drilling, geothermal development.
Product Advantages
◆ Efficient Rock Breaking: Matching different strata with tooth types / structural designs, drilling speed increased by 20–50%, reducing operation time.
◆ Long Service Life and Low Consumption: Wear-resistant materials + precise manufacturing, life extended by 30–100% compared to ordinary drill bits, reducing replacement frequency and downtime losses.
◆ High Stability: Optimized mechanical structure, reducing hole deviation, sticking, high hole formation accuracy, reducing blasting / support risks.
◆ Full Series Compatibility: Covers soft rock to extremely hard rock, shallow holes to deep holes, customizable diameter, thread, tooth type, suitable for various drilling machines / rock drilling machines.
