made from PDC.They have faster drilling speed and longer life when
drilling soft to medium stratum£¨f¡Ü10£©. Drilling holes without the contract og the diameter,the quality of the drilled hole is perfect and decreasing the waste of rolled up powder and anchor-shank. Need not repeat replacing and grinding the bits,and increase supporting efficiency,decrease the labour strength. |
