KellyBar

Kelly bar are designed for the purpose of transferring torques and pressures onto a drilling tool.The kelly used must therefore be treated with as much care as the drilling rig and the tool and bits themselves in order that consistent drilling performance be ensured.

Feature:

◊ Strict selection of raw meterials and forging parts such as drive stub to assure the reliable quality;

◊ Heat treatment is widely used in the key parts such as drive key to improve wear resistance;

◊ With High torsional coefficient,the compression and vibration resistance of kelly bar is higher than average level,high efficient in rock drilling construction;
