Rock Drilling Tools Product Feature 1. Special easy-retraction structure design with relief chamfers on the bit body, reducing withdrawal resistance and
preventing bit sticking.
2. Standard threaded connection for tight matching with drilling equipment, convenient for installation and disassembly.
3. Reasonable arrangement of carbide buttons ensures stable rock breaking and regular borehole forming.
4. The bit body is integrally heat-treated for high impact resistance and wear resistance, adapting to complex rock formation operations.
The retractable threaded drill bit is designed with a special profile and matching thread structure. It performs normal impact rock breaking during drilling. When retracting, its chamfered and relieved shape greatly reduces jamming and friction with the borehole wall, allowing the bit to be pulled out easily and avoiding bit sticking.
