Product Description

Plug Hole Integral Steel High Grade Alloy Steel Tungsten Carbide Tip For Direct Energy Transmission Superior Chip Flushing

Optimizing your small hole drilling operations requires equipment that minimizes energy loss and maximizes impact. Our Integral Rock Drill Steels are engineered for precision in stone quarries and underground mining, offering a seamless, one-piece construction that eliminates the need for extra coupling components.

Technical Specifications Configurations

We provide a comprehensive range of dimensions to suit various rock drills and geological conditions:

Bit Profile: Durable Chisel shaped carbide heads
Available Shanks:
- H19 × 108mm (Ideal for ultra small holes)
- H22 × 108mm (The industry standard for quarrying)
- H25 × 159mm (Designed for heavy duty pneumatic drills)
Drilling Diameter: 17mm - 42mm (Customizable D-range)
Operational Length: Flexible options from 150mm to 9600mm (L)
Premium Alloys: Manufactured from high grade Z708 (40SiMnCrNiMo) and 55SiMnMo steel for extreme fatigue resistance

Core Performance Advantages

Direct Energy Transmission: By integrating the bit and rod, percussion energy is transferred directly from the rock drill to the rock face. This avoids the 10%-15% energy wastage typical of multi piece systems.
Precision Weight Balancing: The optimized 1:1 piston-to-bit weight ratio extends the service life of the tool while delivering more crushing force per blow.
Superior Chip Flushing: Features an advanced central flushing hole for efficient air exhaust, ensuring cuttings are discharged rapidly to prevent secondary crushing and overheating.
Cost Effective Operation: The all-in-one design means no investment is needed for shank adapters or coupling sleeves, reducing your total cost per foot drilled.

Primary Application Fields

Our Plug Hole Steels are the go-to choice for diverse geotechnical and industrial projects:

Dimensional Stone Quarrying: Granite, marble, and limestone extraction
Infrastructure Civil Works: Road construction, trenching, and gas line installation
Mining Tunneling: Underground roadway support and blast hole preparation
Stabilization Projects: Rock anchoring, foundation drilling, and water well industry
