The performance of a diamond core bit hinges on grit crystal friability and thermal stability. We exclusively utilize high-octahedral SDA (Synthetic Diamond Abrasive) crystals coated with titanium or nickel layers. This metallization ensures enhanced retention within the matrix during high-temperature laser welding, preventing premature diamond pull-out under heavy torque loads in Bangladesh aggregate core drilling.
Our engineering team formulates matrix bonds balancing Cobalt (Co), Tungsten Carbide (WC), Bronze (Cu-Sn), and Nickel (Ni). For highly abrasive soft concrete or local Bangladesh brick-aggregate mixes, hard matrix formulas resist micro-erosion. Conversely, for non-abrasive cured concrete infused with hard Sylhet quartz gravel, softer bonds erode predictably to continually expose sharp diamond cutting edges.
Unlike entry-level core bits that rely on low-temperature silver soldering (which fail under dry drilling heat), our premium wet and dry core bits feature high-energy CO2 and fiber laser-welded segments. The metallurgical bond between the diamond segment and the alloy steel barrel exceeds 1,200 MPa shear strength, virtually eliminating segment detachment risks during site operations.
"Information Gain Analysis: In core drilling applications across South Asia, aggregate mineral hardness varies from 3.5 to 7.0 on the Mohs scale. Matching matrix erosion rate to aggregate quartz content is the single most critical factor in achieving the lowest cost-per-meter cut."
| Target Substrate / Material | Aggregate Hardness | Abrasiveness Index | Recommended Bond Formula | Segment Geometry |
|---|---|---|---|---|
| Sylhet Gravel Reinforced Concrete | Mohs 6.5 - 7.0 (High) | Medium | Soft-Medium (B-20) | Roof-Top / Turbo Segment |
| Pikami / Brick-Aggregate Concrete | Mohs 4.0 - 5.0 (Moderate) | Very High | Ultra-Hard (B-80) | Flat Keyhole Segment |
| Chhatak Limestone & Cement Matrix | Mohs 3.0 - 4.0 (Soft) | Low-Medium | Soft Bond (B-10) | Crown / Continuous Rim |
| Imported Indian Granite & Basalt | Mohs 6.0 - 7.0 (Hard) | Low | Extra Soft (B-05) | ZENESIS™ Patterned Array |
| Green Concrete (1-4 Hr Pour) | Variable | Extreme | Hard Bond (B-90) | U-Slot Undercut Protection |
From Dhaka’s rapid elevated transit lines to coastal deep-sea ports in Cox's Bazar and Chittagong, our diamond core bits and cutting tools are tailored for specific regional engineering challenges.
Infrastructure expansion projects like the Dhaka Mass Rapid Transit (MRT), Padma Rail Link, and Matarbari Deep Sea Port require extensive non-destructive testing, anchor bolt placement, and deep core sampling through thick high-strength concrete piers. Our heavy-duty core bits with 1-1/4"-7 UNC standard threads easily drill through heavy rebar (28mm to 32mm deformed steel bars) without segment stripping.
High-rise commercial construction in Gulshan, Banani, and Motijheel demands quiet, vibration-free drilling for Mechanical, Electrical, and Plumbing (MEP) ducting, HVAC penetrations, and fire hydrant lines. Our wet diamond core bits deliver clean, micro-crack-free penetrations in residential and office slabs, protecting surrounding concrete structural integrity.
Export Processing Zones (EPZs) in Chittagong, Savar, and Comilla constantly upgrade garment and manufacturing facility floors. Utilizing our PCD surface preparation grinding heads and diamond cup wheels allows industrial flooring contractors to rapidly strip tough epoxy coatings, polyurea linings, and floor adhesives, preparing smooth substrate profiles for seamless re-coating.
A strategic overview of commercial regulations, customs procedures, and technical performance demands shaping the import of diamond tools into Chattogram and Dhaka.
Importing diamond tools into Bangladesh requires strict compliance with Bangladesh Bank's foreign exchange regulations. As an experienced exporter, we issue precise Proforma Invoices (PI) containing exact Harmonized System (HS) Code classifications (e.g., HS 8207.50.00 for core drill bits), enabling seamless sight L/C opening through major commercial banks like Dutch-Bangla Bank, Eastern Bank, or Standard Chartered Bangladesh.
Sea freight shipments arrive directly at Chattogram Port (CGP) or Mongla Port, with FCL/LCL options customs-cleared via Inland Container Depot (ICD) Kamalapur in Dhaka. Our export packaging features moisture-resistant, vacuum-sealed plastic wrapping inside reinforced double-corrugated export cartons to protect steel barrels from sea breeze oxidation during maritime transit.
Bangladeshi civil contractors are shifting away from cheap, unbranded low-tier core bits that overheat and strip segments after 1-2 meters. Investing in engineered, vertical-integrated diamond bits reduces labor downtime on high-cost drilling rigs, lowering the overall cost-per-meter cut by up to 35% across multi-story infrastructure contracts.
Unlike trading companies or re-label distributors, we own and operate 100% of our production lines, controlling every phase from raw diamond powder selection to final dynamic balancing.
For over two decades, our factory has maintained strict ISO quality management protocols. By executing cold pressing, hot sintering, laser welding, and arbor tensioning completely in-house, we deliver batch-to-batch repeatability that contractors can count on.
Our proprietary ZENESIS™ technology arranges diamonds in precise patterned arrays, providing optimal exposure and even wear. Meanwhile, the DiamondX® series replaces dangerous abrasive wheels with ultra-durable steel core diamond blades for cutting rebar, structural steel, and ductile iron.
We offer robust OEM and private label programs for tool importers, industrial distributors, and machinery brands across Bangladesh. Custom segment heights, specific color coatings, branded laser etching, and tailored arbors (such as 1-1/4"-7 UNC, G1/2", 5/8"-11) are produced to client exact specs.

Concrete reinforced with high quartz Sylhet gravel is notoriously tough and highly abrasive. We recommend our medium-soft bond core bit series (B-20 formulation) combined with roof-top or turbo segments. The softer matrix erodes controlledly, constantly releasing sharp diamond grains to slice through embedded 25mm+ steel rebar without bit glazing or locking up the motor.
We fully support Irrevocable Letter of Credit (L/C at Sight) issued by tier-1 Bangladeshi banks as well as Telegraphic Transfer (T/T). Standard MOQs for core bits start at 20 pieces per diameter, while standard saw blades start at 50 pieces. Custom private-label packaging and OEM color coating orders are accommodated with flexible volume tiers.
For structural concrete, bridge piers, and thick floor slabs, wet core drilling is strongly recommended as water flushes away dense concrete slurry and keeps segments cool. However, for indoor renovation work, electrical conduit installation in brick walls, or areas without immediate water lines, our laser-welded dry core bits with slotted barrels provide excellent heat dissipation when paired with dust extractors.
When drilling soft or non-abrasive material, the diamond matrix may not erode fast enough, causing the segment to feel smooth ("glazed"). If glazing occurs on site, simply perform a few cuts into an abrasive material like a sand-lime brick, sandstone, or a green concrete block to strip back the metal matrix and re-expose fresh, sharp diamond crystals.
We provide a complete commercial documentation suite including: Commercial Invoice, Packing List (showing net/gross weight and cubic measurement), Clean on Board Bill of Lading (B/L), Certificate of Origin (CO), Pre-Shipment Inspection (PSI) reports if requested, and detailed HS code declarations (8207.50.00 for core bits) to ensure smooth customs clearance without demurrage fees.
Yes. While standard barrel lengths are 350mm, 400mm, and 450mm with standard 1-1/4"-7 UNC or G1/2" threads, our machine shop produces custom core bit lengths up to 1,000mm as well as specialized adaptors for Hilti, Husqvarna, and Makita core rigs utilized by Bangladeshi specialized cutting sub-contractors.
