Stable cutting, high wear resistance
Six design advantages behind the Flat Top PDC Drag Bit.
01 / 06 Flat Top Non-Coring StructureThe flat top design provides stable drilling performance and efficient rock contact during non-coring drilling. | 02 / 06 Durable Alloy Steel BodyManufactured with a wear-resistant alloy steel body for longer service life under demanding drilling conditions. | 03 / 06 Flexible PDC Cutter ConfigurationDifferent PDC cutter combinations can be matched according to rock hardness and drilling requirements. |
04 / 06 Suitable for Medium-Hard FormationsDesigned for limestone, dolomite, sandstone, coal seams and other relatively intact medium-hard formations. | 05 / 06 Multiple Thread OptionsDifferent female thread connections can be manufactured according to drilling rigs and drill rods. | 06 / 06 Custom Sizes AvailableStandard sizes are available from 65 mm to 153 mm, with 171 mm customized size available on request. |
Used across grouting, gas drainage and water well drilling
This flat top PDC drag bit is suitable for grouting holes, gas drainage drilling, water well drilling and geothermal drilling. Other applications include engineering construction drilling and general non-coring drilling projects.
01 Grouting HolesStable hole formation for grouting and foundation support projects. | 02 Gas Drainage DrillingReliable drilling in coal seams and gas drainage boreholes. |
03 Water Well DrillingStable penetration for efficient borehole advance in medium-hard formations. | 04 Geothermal DrillingEfficient penetration for geothermal borehole and energy projects. |
Suitable Rock FormationsSuitable for medium-hard and relatively intact formations. Different PDC cutter configurations can be selected according to formation hardness and abrasiveness.
⚠️ Note: Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters, cutter selection and operating conditions. | ||||||||
Multiple PDC cutter options available
Different PDC cutter configurations are available according to drilling conditions.
Standard Standard 1308 PDC CuttersSuitable for general drilling in medium-hard formations. | Reinforced Reinforced Cutter ConfigurationRecommended when better wear resistance and stronger cutting support are required. |
Heavy-Duty Oil-Grade / Heavy-Duty PDC OptionsSuitable for more demanding drilling conditions, depending on formation hardness and drilling parameters. | |
Standard sizes and PDC cutter configurations
Standard sizes from 65 mm to 153 mm. 171 mm and other custom sizes are available on request.
