Key Features & Advantages
1. Superior Diamond Technology
Premium Synthetic Diamonds: High-grade diamond segments ensure maximum cutting efficiency in hard formations.
Optimized Segment Design: Reinforced matrix prevents premature wear and reduces bit balling.
Customizable Grit & Bond Hardness: Adjustable for specific rock types (e.g., coarse grit for fast drilling, fine grit for smooth coring).
2. Robust Construction for Hard Rock
High-Strength Steel Body: Resists bending and deformation under heavy load.
Enhanced Waterways: Efficient coolant flow prevents overheating in deep drilling.
Reinforced Crown Design: Minimizes breakage in fractured or highly abrasive rock.
