Description

Nmlc, Hmlc Wireline Drilling Impregnated Diamond Core Drill Bit/Coal Mine Drill Bit

Product Description:

With bottom discharge diamond core bits, which is suitable for triple tube core barrels, to improve the flushing fluid's erosion against the core during drilling.

The main crown technical parameters of impregnated diamond core bits include diamond grade,size,concentration and quality,matrix hardness and crown shapes.The users can make rational selections according to the formations to be drilled.

To avoid excessive bit wear,tungsten carbide inserts are used on both sides on the waterway,and gage stones are a bit larger.

Surface Set Diamond Core Bits can be used with any type of core barrels. By varying the diamond grade, size, quality, and matrix hardness and crown shapes, the users can satisfactorily drill and core hard and homogeneous formations.

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%.
