Attention:

1.The difference between the outer diameter of the bit and the reamer should be reasonable, the outer diameter of the reamer

is 0.3-0.5mm larger than the outer diameter of the bit, and the hard formation should not more than 0.3mm.

2.When the new bit reaches the bottom of the hole light pressure (1/3 of the normal pressure),

slow turn (about 100rimin), and then continue drilling with normal parameters after the initial grinding for 10 minutes.

3.When drilling in soft rock layer, the pressure should be reduced appropriately. When drilling in intact, medium-hard orhard

rock formations, the pressure on bit should be appropriately increased; When drilling in fractured, fractured and heterogeneous

rock formations, the pressure on bit should be appropriately reduced, generally by 25%-50%.
