Single use ring bit casing drilling bits
Product details:
KINGDRILLING Single use ring bit casing by down the hole (DTH) hammer is used in drilling and casing a hole simultaneously through unstable ground conditions.It is assembled with a single ring bit and pilot bit.
Advantage:
1. Enhance penetration and perpendicularity
2. Deal with straight, oblique hole and other angle holes
3. Material: TIMKIN Steel. Tungsten carbide: YK05, T6 from Element Six in Germany
4. Kingdrilling DTH tools are forged by advanced electron-hydraulic forging hammer, and harness process is managed by multipurpose furnace heat treatment.
5.Quality: More than 40 Years engineer to make sure the quality, 100% inspection

6. What is the materials?
Steel is TIMKEN, Alloy is from T6 from Element Six.
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.
