Drill Bit | Drill Rod | Connection Sleeve | Shank Adapter Functions

The drill bit fractures rock, the drill rod transmits force, the connection sleeve secures connections, the shank adapter drives power—these four core components of rock drilling tools synergize to enable more efficient and reliable mining and tunnel excavation.

Drill tools are important tools in rock drilling operations, mainly including drill bits, drill rods, connecting sleeves, drill tails, etc. The following is a brief introduction to them:

Drill Bit

Function: The drill bit is the part that directly contacts and breaks the rock. According to different rock drilling requirements and rock characteristics, there are various types and shapes of drill bits, such as Down-the-Hole (DTH) Bits, Button Bits, Chisel Bits (single chisel type), Cross Bits (cruciform type).

Application: Drill bits are widely used in mining, tunnel excavation, rock drilling and other engineering projects.

Drill Rod

Function: The drill rod is the part that connects the drill bit and the rock drill, responsible for transmitting the impact force and torque of the rock drill to the drill bit.

Characteristics: Drill rods are usually made of high-strength and high toughness steel to withstand high loads and impacts during rock drilling.

Application: The drill rod is used in conjunction with the drill bit, suitable for various rock drilling operations.

Connection Sleeve

Function: The connecting sleeve is a type of rock drilling tool used to connect the drill tail and the drill rod, ensuring a stable connection between the drill tail and the drill rod.

Type: Common thread types for connecting sleeves include R38, T38, T45, T51, etc. They are divided into full bridge and half bridge connecting sleeves, as well as coaxial connecting sleeves, variable diameter connecting sleeves, etc.

Application: Connection sleeves are widely used in open-pit mining, underground mining, tunnel excavation and other engineering projects.

Shank Adapter

Function: The shank adapter is the connecting part between the rock drill and the drill rod, responsible for transmitting the power of the rock drill to the drill rod.

Characteristics: The shank adapter should have high toughness and no plastic deformation to ensure the stability and efficiency of rock drilling operations.

Application: The shank adapter is mainly used for mining operations, such as underground metal mine tunnel excavation and blasting, railway and highway tunnel excavation, etc.
