Usage Guidelines
Important Considerations for DTH Bit Usage:
- Select the appropriate drill bit based on rock conditions (hardness, corrosion) and drill type (high/low wind pressure)
- Install carefully without force to prevent damage to the bit
- Maintain sufficient air pressure during operation
- Check compressed air system during intermittent work
- Remove any metal objects from the hole immediately
- Monitor bit diameter wear and avoid premature replacement
Hard Rock Drilling Technique
Hard rock drilling utilizes rotary percussive drilling principles with top hammers. Air serves as the primary flushing medium to remove drill cuttings, while a dust exhaust system collects expelled drilling dust.
