Impactors and Drill Bits
High Performance DTH Impactor and Drill Rig Bits for Mining, Quarry & Water Well Drilling
Drill Rig Bits and DTH Impactors are the core working components of a Down-The-Hole (DTH) drilling system, widely used in mining, quarry blasting, water well drilling, geothermal exploration, and rock excavation projects. The DTH impactor delivers high-frequency percussion energy, while the drill bit directly breaks hard rock formations, enabling fast, efficient, and precise drilling performance.
Our DTH drilling tools are engineered with high-strength alloy steel and precision tungsten carbide inserts, ensuring high durability, strong impact resistance, and long service life under extreme working conditions.
The company uses high-quality raw materials, advanced production processes, and rigorous inspection methods to produce high-performance, high-quality impactors and drill bits. We offer impactors and drill bits ranging in diameter from 90mm to 305cm. Each impactor and drill bit is made of high-quality tungsten carbide alloy teeth and precision-machined body shape. After heat treatment, it achieves appropriate hardness, resulting in good surface wear resistance and fatigue strength, suitable for various rock types, whether hard or soft, abrasive or fractured.

What Is a DTH Impactor?
A DTH (Down-The-Hole) impactor is a pneumatic or hydraulic hammer located directly behind the drill bit at the bottom of the borehole. It uses compressed air to drive an internal piston that repeatedly strikes the drill bit.
This design ensures that:
Impact energy is delivered directly to the rock
Energy loss is minimized compared to top hammer systems
Drilling speed is significantly increased in hard rock
DTH impactors are widely used in open-pit mining, quarry drilling, water well drilling, and foundation engineering projects.
What Are Drill Rig Bits?
Drill rig bits (DTH drill bits) are cutting tools installed at the front end of the DTH hammer. They are responsible for breaking rock formations into small fragments through:
High-frequency impact from the hammer
Rotary motion from the drill rig
Tungsten carbide cutting action
Drill bits are the most wear-intensive component in a drilling system and directly affect penetration rate, drilling accuracy, and operational cost.
