Product Description

Rock Bit Series

Our mineral Rock bit products are used in air drilling, such as the development of iron ore, non-ferrous metal ore and open pit mining tools, the products mainly cover 6 "-171 / 2" and other size series, and in various specifications of mining drill products, effectively improve the quality and performance of the drill.

The single rock bit is a kind of deceleration bit, that is, the speed of the tooth is smaller than that of the drill bit. It is mainly used for cutting and broken rock, which is suitable for small drilling operations such as window side drilling and deep drilling under high speed and high drilling pressure.

  • The application field is relatively wide, not only suitable for side drilling construction, but also can be used in medium and deep parallel.
  • The working torque is lower than that of PDC drill bit under the same drilling pressure and formation conditions, which can reduce the problem of small size drilling tool expansion and avoid downhole accidents.
  • The single rock drill has the advantages of three rock drill and PDC drill, which respectively make up for the deficiencies of the two. It is more suitable for the plastic formation than the three rock drill, and also suitable for the hard interlayer and other complex strata that the PDC drill is difficult to deal with.
  • Cooperate with and lower the power drilling tool to achieve high rotation speed and special drilling needs.
  • Dimensions: in sizes 3/4" (95.3mm) - 6 1/8" (155.6mm).
  • Model: YA / YC 437, YA / YC 517, YA / YC 537.

Combination Bit Series

The combined Bit Series are mainly used in Bridges and high-rise bored pile bedrock drilling, railway, water conservancy, construction and other systems, trusted by the majority of users.

Suitable for perfusion bedrock drilling, well and ventilation hole drilling, adapted to strong, medium and slightly weathered rocks and gravel, such as granite, gneiss, sandstone, limestone, shale, etc. The combined tooth wheel drill bit has the following characteristics:

  • According to the principle of hydraulic engineering to remove the sediment at the bottom of the hole.
  • The first double fulcrum rock tooth in China.
  • The back of the palm wear prevention mechanism.
  • Unique and reasonable distribution mode of rock tooth.
  • The protective cylinder protection block further enhances the stability of the drill bit and extends the life of the drill bit. The PZ series combination rock tooth bit has the following properties: Sharp nature, wear resistance, robustness, stability, slag accumulation and self-cleaning, safety.
Frequently Asked Questions
What are the primary applications of the Rock Bit Series?
The Rock Bit Series is mainly used in air drilling operations, including the development of iron ore, non-ferrous metal ore, and open-pit mining tools. They are designed to improve drill quality and performance across various specifications.
What size ranges and models do you offer for the single rock bits?
Our single rock bits are available in dimensions ranging from 3/4" (95.3mm) to 6 1/8" (155.6mm). The available models include the YA / YC 437, YA / YC 517, and YA / YC 537 series.
What are the benefits of the single rock drill compared to a PDC drill bit?
Under identical drilling pressure and formation conditions, the single rock drill operates at a lower working torque, reducing small-size tool expansion and downhole accidents. It also combines the advantages of both three-rock drills and PDC drills, making it ideal for plastic formations, hard interlayers, and complex strata.
Where are the Combination Bit Series typically used?
The Combination Bit Series is widely used in bridge construction, high-rise bored pile bedrock drilling, railway projects, water conservancy systems, and various other civil engineering applications.
What types of rock formations are suitable for the Combination Bit Series?
These bits are engineered for perfusion bedrock, well, and ventilation hole drilling. They adapt exceptionally well to strong, medium, and slightly weathered rocks and gravels, such as granite, gneiss, sandstone, limestone, and shale.
What properties define the PZ series combination rock tooth bit?
The PZ series combination rock tooth bit is characterized by its sharp cutting nature, high wear resistance, robustness, stability, safety, and excellent slag accumulation and self-cleaning capabilities.
