Maintenance Strategies for Extending the Life of Impregnated Drill Bits

Proper maintenance is essential for maximizing the lifespan and performance of impregnated drill bits. Routine care ensures efficient operation and reduces downtime.

Maintenance Best Practices

1. Cleaning After Use:

• Remove debris and slurry using water or air pressure.

• Prevents clogging and ensures smooth cutting.

2. Inspect for Wear:

• Check the matrix for uneven wear or exposed diamonds.

• Replace bits showing excessive damage to avoid operational inefficiencies.

3. Sharpening:

• Re-sharpen dulled bits to maintain cutting performance.

• Specialized tools can restore the diamond surface effectively.

Rig-Specific Maintenance Tips

1. Exploration Coring Drill Rigs:

• Regularly check for core recovery quality to assess bit wear.

• Maintain hydraulic systems for consistent performance.

2. Portable Full-Hydraulic Core Drilling Rigs:

• Lubricate moving parts to reduce friction and wear on the bit.

3. Mud Pump Core Drilling Rigs:

• Ensure slurry is free from contaminants that might damage the bit or matrix.

Long-Term Storage

• Store bits in a dry environment to prevent rusting or matrix degradation.

• Use protective covers to shield diamonds from damage.
