Drillmax – Your Reliable Partner for Wireline Coring & Geological Drilling Tools
🔹 （Geological Drill Bits）
Geological drill bits are the frontline drilling tools mounted on drill rods. By applying axial pressure and rotation (or impact rotation), sintered or welded abrasive materials break down rock formations efficiently.Drillmax Advantage: Our drill bits are engineered for robust adaptability to diverse geological drilling scenarios, delivering stable performance, excellent compatibility, and simplified selection for your projects.
🔹 （Bits Classification）
By Manufacturing Process
- Hot-press Sintering: Used for regular diamond bits
- Pressureless Impregnation: Applied for high-matrix diamond bits and reaming shells
- Secondary Inlay Welding: Ideal for TC bits and PDC bits
By Product TypeTC bits, PDC bits, surface-set diamond bits, impregnated diamond bits, and special-purpose bits
By Product StructureWireline coring bits, double pipe bits, single pipe bits, drill pipe shoe bits, and casing shoe bits
🔹 （Cutting & Grinding Materials）
Our drill bits utilize premium cutting and grinding powders, including:
- Tungsten Carbide: A high-hardness, high-strength alloy with exceptional wear resistance and toughness, produced via powder metallurgy. Available in octagonal, needle-shaped, and crushed alloy grades to suit various drilling demands.
- Diamond & PDC Chips: Synthetic diamonds and polycrystalline materials ensure efficient rock crushing and reliable drilling system operation.
🔹 （Diamond Materials）
Diamond is the hardest known cutting material. While natural diamonds are rare and costly, synthetic diamonds (accounting for 90% of global production in 2021) offer superior hardness, wear resistance, and consistent crystal shape – making them the ideal choice for industrial drilling.Drillmax Selection: We use only top-grade synthetic diamonds with a single-grain compressive strength >400N, matched to your bit type:表格Specification (mesh)Grain Size (mm)Application12/141.4Surface-set diamond bits16/181.1Surface-set diamond bits20/250.8Impregnated bits & reaming shells30/350.45Impregnated bits & reaming shells35/400.4Impregnated bits40/450.35Impregnated bits
