Product Description

High Quality Mining Carbide Tool DTH Button Hammer Bits Drilling Tools

Product Description

KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.

Rock drill bits Shank type:M3,M4,M5,M6,M8,M1,M12

DTH hammer bits hole diameter: 3'', 4'', 5'', 6'', 8''(85mm-350mm).

7. How to choose the suitable head face of the DTH drill bit?

a. Concave:

Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.

b. Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

c. Flat:

Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
