Usage and Maintenance Tips：
Avoid sudden reverse rotation to prevent PDC cutter detachment.
Ensure sufficient air flow and pressure to extend bit life.
Run-in new bits at low speed for the first 30 minutes.
Reduce drill pressure and speed in harsh conditions to prevent breakage.
Inspect the hole for debris before changing bits.
Regularly replace stabilizers for stable drilling.
Keep the drilling area clean to prevent debris interference.
Inspect threads and teeth before installing new bits.
Ensure proper lubrication and secure connection before use.
Avoid bent drill rods to prevent uneven force and wear.
Select the appropriate bit for specific conditions and methods.
Inspect the bit thoroughly before use.
