Manufactured to NAS 965, DIN 6535, and ISO 9001:2015 aerospace standards. Engineered for superior performance in heat-resistant superalloys, titanium, and carbon-fiber composites (CFRP).
As Central Asia emerges as a major cross-border logistical corridor under the Belt and Road Initiative (BRI) and Trans-Caspian International Transport Route (TITR), the Republic of Kazakhstan is rapidly scaling its domestic aviation maintenance, repair, and overhaul (MRO) infrastructure. Key aviation facilities across Almaty (ALA), Astana (NQZ), and Shymkent (CIT) require aerospace-compliant cutting tools capable of handling extreme operational demands.
As a leading China-based manufacturer and exporter of aerospace cutting tools, we deliver high-performance M35/M42 Cobalt Twist Drills, NAS 965 Threaded Shank Drills, and Internal Coolant Solid Carbide Systems directly to Kazakhstan’s flight repair depots, defense workshops, and commercial air transport operators.
Our tooling engineering addresses the specific metallurgic challenges of modern airframes—including 2024-T3/7075-T6 aluminum alloys, Titanium Grade 5 (Ti-6Al-4V), Inconel 718, and modern composite laminates—ensuring precise tolerance control without burr formation or micro-cracking.
Aircraft drilling demands zero-defect execution. A single out-of-round rivet hole in a pressurized fuselage sheet can introduce stress concentrations that compromise structural integrity. Our manufacturing protocols integrate CNC 5-axis Rollomatic and Walter grinding technologies to guarantee point concentricity within 0.003 mm and web thickness uniformity across large batch runs exported to Central Asia.
M35 (5% Cobalt) and M42 (8% Cobalt) high-speed steels retain hardness at cutting edge temperatures up to 650°C, making them essential for work-hardening stainless steels and titanium alloys used in engine nacelles.
Specifically engineered carbide substrates and nano-coatings resist brittle fracture under extreme sub-zero ambient maintenance operations in Northern Kazakhstan (Astana, Karaganda regions).
1/4-28 threaded shank adapter drills fully compatible with pneumatic right-angle drill motors (Nova®, Desoutter, Dotco) and microstop depth-control cages employed by Kazakh line technicians.
Our tooling lines are tailored for specific structural repair challenges encountered by engineers, procurement directors, and maintenance personnel in Kazakhstan.
Heavy C-Check and D-Check maintenance on Airbus A320/A321 family and Boeing 737/767 fleets operated by domestic flag carriers. Our 135° split point M35 cobalt twist drills allow clean penetration through multi-layered aluminum skins and fastener holes without requiring pre-drilling pilot holes, drastically reducing turnaround time (TAT).
Overhaul and modernization of military transport helicopters (Mi-8/Mi-17 series) and defense transport aircraft. Utilizing NAS 965 threaded shank stubby drills in tight-clearance rotor heads and gearbox housings, ensuring concentric fastener installation under restricted access conditions.
Maintenance of offshore support helicopters and specialized air freight fleets servicing the Kashagan and Tengiz oilfields. Drilling high-strength stainless steel fasteners and marine-atmosphere corrosion-resistant alloy plates demands our Solid Carbide Internal Coolant Drills to withstand harsh saline and chemical environments.
A practical engineering baseline for tool crib managers and manufacturing planners selecting optimal cutting geometry for aerospace materials.
| Substrate Material | Recommended Drill Series | Point Geometry & Coating | Operating Characteristics |
|---|---|---|---|
| 2024-T3 / 7075-T6 Aluminum | M35 Cobalt / Jobber Length Twist | 135° Split Point, Bright / TiN | Prevents burr formation; optimal chip evacuation in high RPM hand-held air tools. |
| Titanium Grade 5 (Ti-6Al-4V) | Solid Carbide Coolant-Through (3XD–8XD) | 135° Heavy-Duty Web, TiAlN Nano-Coated | Low cutting speed, heavy continuous feed. Internal coolant eliminates thermal expansion. |
| Stainless Steel (15-5PH / 17-4PH) | M35 Cobalt / DIN 6537 Solid Carbide | 135° Split Point, TiSiN Coated | High red hardness prevents edge degradation during work-hardening phases. |
| CFRP / Composite Laminates | Solid Carbide Brad Point & Dagger Drills | Brad Point / 4-Facet Dagger Geometry | Shears outer composite fibers cleanly before exit to eliminate surface delamination. |
| CFRP / Titanium Stack-ups | Custom Double Margin Carbide Drills | Special Stepped Dagger Geometry | One-shot hole sizing; second margin burnishes hole wall to reamer-quality fit (H7 tolerance). |
Direct factory supply, stringent quality control, and streamlined Eurasian customs logistics.
We provide full EAC (Eurasian Conformity) documentation, certificates of origin, and optimized land transport freight options via Khorgos Dry Port and Dostyk rail hubs. Enjoy rapid 5 to 7 day door-to-door transit to Almaty, Astana, and Karaganda.
Whether you require non-standard stepped drill diameters, special overall lengths (NAS 907 Type J extension drills), or custom pilot countersinks, our engineering team manufactures to your exact technical blueprints within 10 business days.
By leveraging China's advanced raw material tungsten supply chains and automated CNC grinding clusters, we offer Kazakh buyers premium-grade aerospace tooling at 30% to 45% lower procurement costs compared to Western European alternatives.
We provide comprehensive export documentation including Commercial Invoices, Packing Lists, Certificates of Origin (Form A / Form EC), and EAC declaration support. Goods are dispatched via international express or direct overland trucking through Khorgos gateway.
We recommend our M42 (8% Cobalt) or Solid Carbide Internal Coolant Drills featuring a 135° split point and heavy web thickness. Low cutting speeds (15–25 m/min) combined with high, positive feed force prevent work-hardening of the titanium sheet.
Double margin drills carry a secondary guide margin on each land. This provides continuous contact with the hole wall, eliminating chatter, preventing hole bell-mouthing, and producing reamer-quality hole finishes in a single operation.
Yes. All our NAS 965 Type D drills feature standard 1/4-28 UNF threads and precise shank geometry, fully interchangeable with standard microstop countersink cages and right-angle pneumatic motors used globally.
Absolutely. Our micro-grain tungsten carbide substrates undergo specialized stress-relieving heat treatment and multi-layer PVD coating (TiAlN/TiSiN), maintaining micro-structural toughness down to -45°C ambient operational conditions.
For standard stocked sizes (jobber length, M35 cobalt twist drills), MOQ is 10 units. For custom engineered tooling (special stepped diameters or non-standard NAS lengths), our MOQ starts at just 50 units with rapid prototyping.
Internal coolant ducts deliver high-pressure fluid directly to the cutting shear zone. This instantly flushes hot chips out of the flute groove, drastically reducing thermal shock and extending tool life up to 300% in stainless steel processing.
We accept T/T (Telegraphic Transfer), Irrevocable Wire Transfers, and Letters of Credit (L/C) for bulk contracts. Flexible payment terms are available for verified long-term aviation MRO partners and official distributors.
