Product Description
CIR series 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. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.
Shank type: CIR50,CIR60,CIR70,CIR80,CIR90,CIR110,CIR130,CIR150,CIR170
CIR76,CIR90 and CIR110 are most widely used.
How to choose the suitable head face of the DTH drill bit?
- Concave:
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful. - Convex:
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate. - 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.
