Button Drill Bit – High-Performance Rock Drilling Tool

The Button Drill Bit, also known as a Carbide Button Drill Bit, is a specialized rock drilling tool designed for high-efficiency penetration and long service life in hard and abrasive rock formations. Its design features tungsten carbide buttons embedded in a heat-treated steel body, allowing it to fracture rock efficiently, maintain accuracy, and reduce overall drilling costs.

Button bits are widely used in quarrying, mining, tunneling, civil engineering, and construction projects, making them essential for stone extraction, blast hole preparation, foundation drilling, and underground works. Their durability and precision make them the preferred choice for DTH hammers, top hammer rigs, and pneumatic rock drills.

🔹 Key Features

1. Tungsten Carbide Buttons

High-quality tungsten carbide buttons are embedded on the bit face to resist abrasion and impact, ensuring long service life and consistent performance in medium to hard rock formations.

2. Heat-Treated Steel Body

The bit body is forged and heat-treated, providing shock resistance, structural integrity, and durability, even under heavy-duty drilling conditions.

3. Optimized Button Layout

Strategically spaced carbide buttons maximize impact energy transfer, reduce vibration, and produce cleaner, more uniform holes. This design also improves penetration speed and drilling efficiency.

4. Flushing & Chip Removal

Many button bits feature flushing holes to remove rock debris, preventing clogging and maintaining continuous drilling performance.

5. Versatility Across Rock Types

Button bits are suitable for granite, basalt, limestone, sandstone, and other medium-hard to hard rock, making them ideal for quarrying, mining, and tunneling.

🔹 Applications

Button Drill Bits are designed for:

Stone quarry drilling: precise block extraction and hole preparation

Mining and blasting: drilling blast holes in hard rock formations

Civil engineering and tunneling: foundation, rock anchor, and road construction

Geotechnical drilling: soil stabilization and rock testing

Anchor and rock bolt installation: accurate, durable holes in granite or basalt

🔹 Types & Design Considerations

Button Shapes & Configurations

Spherical / Ballistic buttons: optimized for hard rock penetration

Conical / Convex buttons: suitable for medium-hard formations

Concave / Depressed buttons: improve cutting efficiency in abrasive rock

Thread & Shank Compatibility

Common thread types: R25, R32, T38, T45, T51

Ensure the bit diameter and thread match the drilling rig for stable operation and safety

Grit & Rock Hardness Considerations

Hard rock: choose bits with higher button density and spherical or ballistic buttons

Medium-hard rock: standard conical or convex button configurations

Soft rock: fewer buttons with more aggressive spacing
