View DetailsChittagong, the primary seaport and industrial hub of Bangladesh, represents a highly complex geological terrain. The region is characterized by the Chittagong Hill Tracts (CHT), a continuation of the Arakan Yoma fold belt. The stratigraphy consists of thick tertiary sedimentary sequences featuring layers of sandstone, siltstone, shale, and highly abrasive clay.
For contractors and developers working on major infrastructure projects such as the Matarbari Deep Sea Port, the Karnaphuli River Tunnel (Bangabandhu Sheikh Mujibur Rahman Tunnel), and extensive rail links, geological stability is the primary challenge. Boreholes in these terrains are highly prone to collapse due to loose formations and high groundwater tables. This is where premium Down-The-Hole (DTH) drill bits and self-drilling anchor systems are crucial.
As a leading manufacturer of rock drilling tools, we engineer specific metallurgical solutions. Our DTH bits feature premium tungsten carbide button configurations designed specifically to resist the aggressive abrasion of Chittagong's silty sandstone, ensuring maximum penetration rates and cost-per-meter efficiency.
Procuring heavy rock drilling equipment for large-scale Bangladeshi infrastructure demands strict compliance with international standards and local customs requirements. Import activities through the Chittagong Port require accurate HS Code classification, ISO certifications, and detailed Mill Test Certificates (MTC) to prevent customs delays.

High structural yield strength anchor bar, suitable for the long-span tunnels of the Chittagong hilly regions.
View DetailsTo withstand the highly abrasive sandstone and coastal soil profiles in Chittagong, our DTH bits are manufactured with state-of-the-art metallurgical technologies.
Tungsten Carbide Insert (TCI) Optimization: We use ultra-premium tungsten carbide buttons, specifically configured for rock hardness and density. Spherical buttons provide excellent resistance to fracturing in high-impact operations, while ballistic buttons increase penetration speed in sedimentary sandstone.
Superior Steel Alloy (20CrNiMo / 23CrNi3Mo): By employing ultra-high-strength steel alloys and implementing precise computer-controlled heat treatment (carburizing and shot peening), we maximize fatigue strength and prevent shank failures during intense rotation.
Optimized Flushing Passages: DTH drilling requires excellent air/water flushing to clean the drill hole. Our bit designs feature optimized face shapes and flushing holes to ensure debris is cleared instantly, avoiding secondary grinding and reducing wear.

Chittagong’s soil consists heavily of weak sedimentary rock layers, soft clay, and silt. During traditional anchor installation, boreholes collapse easily before the anchor bar is inserted. Self-drilling anchors act as both the drill string and the grout pipe, drilling and grouting simultaneously, which eliminates the casing step and guarantees borehole structural integrity.
Coastal environments accelerate hydrogen embrittlement and surface corrosion of high-carbon steels. Shandong Kat Drilling Tools employs alloy compositions high in Chromium and Nickel (such as 23CrNi3Mo) alongside advanced rust-prevention coatings, ensuring the drilling rods and couplers maintain their structural integrity during storage and drilling.
For the abrasive sandstone found throughout the Chittagong Hill Tracts, we recommend a Convex Face or Flat Face with spherical tungsten carbide inserts. This configuration offers maximum durability against high-impact forces and prevents premature bit body wash.
Yes. We manufacture high-compatibility shank adapters for major drilling brands, including Atlas Copco, Furukawa, Sandvik, and Ingersoll Rand. Our shank adapters ensure efficient transmission of kinetic energy from the hydraulic drifter to the drill rods, minimizing internal shock and wear.
