DTH Hammer Bit
Product Description
Our Down-The-Hole (DTH) hammer bits are engineered for high-performance drilling in the toughest rock formations, including granite, basalt, and hard limestone. Designed with premium tungsten carbide buttons and a reinforced steel body, these bits deliver exceptional durability and penetration rates.
Key Advantages:
✔ Optimized Button Layout – Strategically placed carbide inserts ensure even wear and superior crushing efficiency.
✔ High-Strength Steel Shank – Heat-treated for impact resistance, reducing breakage risk in demanding conditions.
✔ Multiple Bit Profiles – Flat, convex, and ballistic shapes available for varied rock hardness and drilling speeds.
✔ Compatibility – Fits leading DTH hammer models (e.g., COP, Mincon, Sand vik) for seamless integration.
Ideal for mining, quarrying, and construction, our DTH bits offer extended lifespan and reduced downtime. R
