Specifications
Model: H22
Dimensions: 22mm in diameter and 108mm in length
Taper Angle: 11°
Type: Hexagonal Cone Drill Rod
Characteristics
High Strength and Wear Resistance:
Constructed from high-strength alloy steel, the drill rod’s main body can endure substantial drilling pressure and torque.
The tungsten carbide or other hard alloy blade design enhances the drill rod’s wear resistance and prolongs its lifespan.
Hexagonal Design:
The hexagonal handle facilitates easy connection with the drilling machine, ensuring stable rotation and propulsion.
This design also offers better leverage during drilling, making it simpler to insert and rotate the drill rod.
Cone Design:
The conical head of the drill rod aids in gradually enlarging the hole during drilling, reducing drilling difficulty.
The conical shape also provides superior cutting performance and extends the drill rod’s service life.
Versatile Applications:
Suitable for drilling various rocks and minerals, including hard, medium-hard, and soft rocks.
Widely applied in mining, tunnel excavation, and stone quarrying industries.
