Custom OEM/ODM manufacturing conforming to NAS 965 Type D, DIN 6535/6537, and stringent aerospace quality standards for Nordic manufacturing excellence.
As the European manufacturing landscape pivots toward zero-defect tolerance, sub-zero fatigue resistance, and micro-alloy structural assembly, the Finnish industrial ecosystem—ranging from defense aerostructures in Jämsä to naval component machining in Turku and precision machinery hubs in Tampere—demands tool integrity that exceeds standardized ISO twist drills. NAS 965 Threaded Shank Adapter Drills (Type D 1/4-28 UNF) represent the benchmark for restricted-access, high-thrust drilling applications where conventional chucking systems fail due to spatial limitations or chatter induction.
Engineered specifically for right-angle air motors, positive-feed microstop units, and automated drilling jigs, our factory-direct OEM and ODM NAS 965 drill bits solve the critical engineering challenge faced by Nordic OEMs: achieving perfect hole roundness and zero exit-burr delamination in stacked materials (Titanium Ti-6Al-4V, 7075-T6 Aluminum, Inconel 718, and Carbon Fiber Reinforced Polymers - CFRP) under tough, sub-zero operating environments.
Conforms strictly to National Aerospace Standard NAS 965 Type D dimensions, guaranteeing zero pitch deviation and perfect axial lock-up in all standardized microstop cages and angle attachments.
Eliminates center-punching and drill walking on curved airframe skins or hard-surfaced stainless steel. Reduces thrust force by up to 40% compared to standard 118° points.
Secondary margin lands burnish the hole wall during penetration, achieving H7 tolerance and surface finishes below Ra 0.8 µm, bypassing separate reaming cycles in structural joints.

Threaded shank drills must operate inside enclosed wing boxes, fuselage rib channels, and tight turbine housings where standard drill chucks cannot physically fit. We manufacture five standardized NAS 965 length classes:
Finland’s industrial landscape relies heavily on specialized metallurgical performance due to severe environmental conditions and advanced manufacturing standards. Our NAS 965 Threaded Shank Drills are custom tailored to match key Finnish regional manufacturing clusters:
In military aircraft maintenance (such as F/A-18 Hornet and upcoming F-35 fleet integration) and Patria aerospace defense manufacturing, our M42 Cobalt and Solid Carbide NAS 965 drills enable burr-free single-pass drilling through High-Strength 7050 Aluminum and Titanium Ti-6Al-4V airframe bulkheads.
Naval architecture built by Meyer Turku and arctic marine equipment suppliers requires drilling high-yield duplex stainless steels (e.g., 2205, 2507) and thick hull plating. Our cryogenic-treated M35 drills withstand thermal shock and work-hardening during tight-access structural stiffener installation.
For brands like Ponsse, Valmet, and John Deere Forestry, internal hydraulic valve blocks and boom arm assemblies require ultra-precise threaded adapter drills to clear internal burrs and finish oil ports in constrained spaces without removing large component assemblies.
A frequent root-cause failure in Nordic outdoor MRO operations (e.g., northern Finland mining facilities in Sodankylä or aviation hangars in Rovaniemi) is micro-chipping of cutting edges caused by cold-brittleness. Our custom OEM thermal treatment process includes a triple-tempered cryogenic bath at -196°C. This converts retained austenite to stabilized martensite, increasing matrix toughness by 28% and ensuring that high-torque threaded shank drills maintain structural elasticity even at sub-zero field service temperatures (-30°C to -40°C).
Finland is leading Northern Europe in sustainable, low-carbon manufacturing. Modern procurement protocols established by Finnish industrial buyers prioritize tool life longevity, minimal lubricant consumption (MQL), and recyclability. Our ODM supply chain aligns directly with these evolving market dynamics:
The Finnish lightweight transport and aerospace sectors are rapidly expanding their adoption of carbon-fiber composites stacked over titanium or aluminum structural frames. Standard twist drills cause Severe Delamination (type I and type II fiber peel-up) when transitioning between soft matrix carbon and hard metal alloys. Our OEM solution provides custom-ground Dagger-Point NAS 965 Carbide Drills with polished flutes. The multi-angle point shears polymer fibers cleanly before piercing the metal substrate, maintaining strict diameter tolerances across the entire stack thickness.
To reduce hazardous coolant waste in line with Finnish environmental legislation (Ympäristönsuojelulaki 527/2014), our solid carbide NAS 965 drills can be manufactured with internal micro-coolant channels (Coolant-Through) optimized for 5 to 10 bar MQL mist systems. Specialized AlTiN and Diamond-Like Carbon (DLC) coatings lower friction coefficients down to μ = 0.1, suppressing thermal build-up during dry structural assembly.
Automated manufacturing centers in Oulu and Espoo are replacing manual handheld air drills with robotic cobot end-effectors equipped with 1/4-28 UNF adapter spindles. Our high-precision ground shanks ensure dynamic runout under 0.003 mm, preventing spindle vibration and protecting expensive automated microstop heads against premature bearing failure.
