This product is used for construction of gas drainage drilling, water exploration drilling and grouting drilling in coal mines. The steel body bit is suitable for soft-medium hard formations (f = 4-8). Carcass drills are suitable for medium-hard to partially hard formations (f = 6-10) or strong abrasive formations, and should not be used in complex formations such as fractures and fissures.
[Design features]
