what are sacrifical Drill bit?
Sacrificial drill bits are specialized drilling tools designed to remain in the ground after drilling.
They are used with casing systems to advance the casing while drilling, ensuring borehole stability in loose or unstable ground. These bits are commonly applied in foundation, anchoring, and geotechnical drilling projects.
how many types of sacrifical Drill bits?
Sacrificial drill bits are available in several types, each designed for specific ground conditions and drilling requirements.
Based on cutting structure and wear protection, sacrificial drill bits are commonly classified into five main sacrificial drill bit types to ensure stable casing advancement and efficient drilling performance.
EX Type (Hardened Cross Bit): This type is suitable for loose to medium-dense soil, offering stable penetration and reliable casing advancement while maintaining good control in softer ground conditions.
EXX Type (Cross Bit with Carbide Inserts): Designed for soft rocks with low to medium hardness, this bit combines a cross structure with carbide inserts to improve wear resistance and drilling efficiency.
ES Type (Flat Face Hardened Button Bit): Ideal for broken ground and soft sandstone or limestone, this bit provides balanced cutting performance and stable drilling in fractured formations.
ESD Type (Sunken Hardened Button Bit): This type is used in weathered rock and stone walls, with recessed buttons that improve durability and reduce wear during extended drilling operations.
ESSD Type (Sunken Hardened Button Bit): Similar to ESD but with enhanced button protection, this bit is suitable for highly weathered rock and stone walls, offering longer service life and consistent drilling performance.
what are sacrifical Drill bits used for?
