Maintain Stable Air Pressure
Insufficient air pressure causes poor cuttings discharge, while excessive pressure increases impact fatigue on the buttons. Keep the pressure within the recommended range.
2. Choose the Correct Bit Type & Button Shape
Different formations require matching bit types—spherical buttons for hard rock, ballistic buttons for medium-hard formations.
3. Avoid Dry Firing and Jamming
Dry firing accelerates wear; forcing drilling during jamming can damage the bit structure.
4. Control Feed Force and Rotation Speed
Too much feed force increases risk of button breakage; too little
reduces penetration rate.
5. Use High-Quality Drill Grease
Lubrication reduces wear on connections and extends the entire drilling system’s life.
6. Inspect Wear Regularly
Replace the bit when buttons are broken, cracked, or excessively worn to avoid damage to the hammer.
7. Keep the Borehole Clean
Accumulated debris increases counter-impact and causes premature failure.
8. Ensure Clean Water or Air Supply
Contaminated water or air causes internal abrasive wear.
