1. Cutting rings with rock drilling bits and releases the internal stress of rock.
2. Cutting with the method of rolling and squeezing can increase the anti-wear ability of the barrel.
3. Small barrel facilitates the coring operation, large barrel performs stage breaking.
4. Extended Lifespan Design The barrel design incorporates heavy-duty spiral wear-resistant strips. Because of this protective feature, the tool can prevent surface abrasion and subsequently extend the overall lifespan of the equipment.
5. Broad Geological Compatibility This tool is engineered for maximum versatility. Therefore, it is perfectly matched with backfill layers, moderately weathered rock, and various types of bedrock.
