Specification
Thin kerf bits provide a larger core size for the same diameter hole and ensure higher penetration rate. TW series of bits are especially suitable for portable and underground rig drilling, which could increase the penetration rate , drill depth ability and reduce the weight of ITH systems.
Superiorperformance
TW bits cutting ability has been developed to allow high penetration rate or lowweight on bit when formation demands it. The exceptional durability and superior abrasion resistance have proven toincrease drilling performance for a broad range of applications.
