Function characteristics
1, bit long life: diamond surface extended use wear-resisting degree, the drill its service life is more than five times as much as hard alloy.
2, high drilling efficiency: the more wear-resisting, saves the time and cost, replace drill and greatly improve the work efficiency;
3 and drill to scratch to broken rock; Set the diamond crystal, high resistance to gather, the diameter performance is good, can make the cutting teeth to receive efficient use;
5, use range: practice proves that the drill is applicable to carbonate, limestone, chalk rocks, clay rocks, silty sandstone, sandstone in soft, hard (drillability of rocks below the rank 9) formation of drilling, with general of the drill bit, especially compared into 6-8 class layers, effect is particularly significant;
