Rock Drilling: Innovative Button Bits
Special-structured bits open new paths for granite and basalt drilling.
Button bits lead this innovation: carbide buttons create high-stress points to crush rock efficiently.
In granite, button bits penetrate deeply, breaking rock with high-frequency impacts. Drilling speed rises by ~30% vs traditional bits.
Tips for rock drilling with special bits:
- Use button bits on basalt to handle brittleness, reducing tooth cracking risks.
- Try combo bits: PDC front cuts, roller cones assist. Adapt to rock layers flexibly.
- Leverage structure strengths for interbedded formations. Cut losses and boost efficiency.
Button bits and combo designs enhance performance in tough granite and basalt.
