Product Description: 

Roschen CIR series hammer bits are used with Down-the-hole hammers for hole drilling through various rock types. In conjunction with DTH hammers, hammer drill bits are designed with spline drives to rotate bits on the ground. Drill bits are available in a variety of different sizes and styles so they can drill different sizes of holes. Our range of Down the Hole (DTH) bits are manufactured using high quality materials to provide you with a good balance between penetrability and bit life.

Calf type: CIR50, CIR60, CIR70, CIR80, CIR90, CIR110, CIR130, CIR150, CIR170, CIR200, CIR250, CIR300

CIR76, CIR90 and CIR110 are most widely used.





















How to choose a suitable head face for DTH drill bit?

Concave:
Suitable for all kinds of formations, especially for deep well drilling, perpendicular holes are magnificent.

Convex:
Suitable for the formation of medium hardness layers, good drilling efficiency, perpendicular to medium boreholes.
 

Flat:
Suitable for special hard formation strata, especially for fractures, spaced gaps and complex formation drilling effects are excellent, has good perpendicularity of the borehole.
