Our eccentric drill bit adopts a unique asymmetric offset structure, with the bit center deviating from the central axis. During rotation, it generates stable lateral centrifugal force to efficiently ream hole walls and expand borehole diameter. Featuring an integrated robust steel body and premium carbide/PDC cutters, this drill bit delivers high hardness, strong wear resistance and excellent impact toughness, ensuring stable drilling performance in complex working conditions.

High-precision concentric drill bit features a symmetric balanced structure for straight-hole drilling with minimal deviation. Adopting premium carbide cutting teeth and high-strength steel body, it delivers outstanding wear resistance and impact toughness. Designed for simultaneous drilling and casing operations, this bit ensures stable hole formation in loose, broken and complex geological formations. Ideal for water well drilling, geotechnical exploration, foundation construction and geothermal drilling, offering high penetration efficiency and long service life.

Cross drill bit features a cross-shaped symmetric blade structure with high rock breaking efficiency and smooth chip removal. Made of high-quality alloy steel and welded carbide buttons, it has high strength, good impact resistance and wear resistance. Suitable for rock drills and DTH drilling rigs, widely used in mining, tunneling, slope support and hard rock foundation drilling.

Our button bits are premium rotary rock drilling tools engineered for high-efficiency and heavy-duty rock drilling. Each bit is forged from high-strength alloy steel body and embedded with high-density tungsten carbide spherical buttons, featuring excellent hardness, impact resistance and ultra-low wear rate.
Adopting professional hot pressing and multi-stage heat treatment technology, the drill bit ensures tight combination of carbide buttons and steel body, avoiding tooth falling and cracking under high-frequency impact and rotary drilling.
Available in multiple thread specifications (R25, R32, R38, T38, T45, T51) and diameter sizes. Widely compatible with rock drills and drilling rigs, ideal for mining, quarrying, tunnel excavation, water well drilling, blasting hole drilling and foundation engineering. It greatly reduces drilling cost per meter and extends service life for long-term field operation.

Our coal cutting bits are professional heavy-duty mining cutting tools specially engineered for underground coal mining, roadway tunneling and coal seam drilling. Manufactured with high-grade alloy steel body and premium tungsten carbide tip through high-temperature vacuum sintering and precision heat treatment, the picks feature exceptional hardness, superior impact resistance and excellent wear resistance.

High-strength rotary drilling teeth, also known as foundation bullet teeth, are professionally engineered for rotary piling rigs, auger buckets and core barrels. Adopting premium tungsten carbide inserts and heat-treated alloy steel body, these drilling teeth feature excellent wear resistance, high impact toughness and stable welding performance. Suitable for various complex geological conditions, widely used in foundation piling, road construction and engineering drilling.
