OSG Korea Corporation Overview
OSG Korea Corporation (also known as K-OSG) is a major South Korean manufacturer and distributor of high-precision cutting tools, thread-making tooling, and industrial machining solutions. Originally established in June 1976 as OSG Precision Tool Trading Company, the organization was later restructured in 1985 as a joint venture with Japan’s OSG Corporation. Headquartered in Daegu, South Korea, OSG Korea operates major production facilities across the Seongseo Industrial Complex and Hosan-dong regions.
The company focuses on manufacturing tools that enable high-efficiency, high-speed, and high-precision machining across automotive, aerospace, shipbuilding, electronics, and general machinery manufacturing industries.

Core Manufacturing and R&D Infrastructure
OSG Korea maintains dedicated manufacturing sites and research units equipped with multi-axis CNC grinding machines, specialized heat treatment furnaces, advanced physical vapor deposition (PVD) coating systems, and micro-geometry inspection equipment.
- Tool Coating Technology: Develops proprietary tool coatings (including TiAlN, DLC, and specialized nano-composite coatings) designed to withstand extreme thermal loads and extend tool life when machining hardened steels, titanium, and heat-resistant superalloys.
- Micro-Grain Carbide Production: Utilizes ultra-fine and micro-grain solid carbide substrates to prevent tool chipping and maintain edge sharpness under high-speed milling and drilling conditions.
- Quality and Environmental Certifications: Operates quality and environmental management systems compliant with global standards, including ISO 9001 and ISO 14001 certification.
Key Products and Tooling Solutions
OSG Korea offers a comprehensive catalog of industrial tooling across five main product categories:
1. Thread-Cutting Tools (Taps)
Taps represent one of the company's core product lines, designed for high-precision female thread processing.
* Application-Specific Taps: Engineered for specific workpiece materials, including alloy steel, stainless steel, cast iron, aluminum, and hardened steels up to high HRC levels.
* Spiral Point and Spiral Flute Taps: Optimized for through-hole and blind-hole tapping operations with superior chip evacuation properties.
* Form/Roll Taps: Cold-forming taps that produce internal threads through plastic deformation without generating chips, increasing thread tensile strength.
2. Milling Cutters (End Mills)
OSG Korea manufactures high-performance end mills for roughing, finishing, profiling, and high-speed die and mold machining.
* HS and HS+ End Mill Series: Specialized carbide end mills capable of milling materials hardened up to 70 HRC.
* Micro-Diameter End Mills: Precision miniature end mills engineered for delicate electronics, medical device manufacturing, and detailed mold making.
* Multi-Flute Variable-Helix End Mills: Designed to minimize chatter and vibration during heavy side-milling and slotting operations.
3. Drills and Holemaking Tools
Designed for high-productivity drilling operations across automotive, aerospace, and heavy equipment industries.
* Solid Carbide Drills: High-penetration drills featuring internal coolant holes (coolant-through) for high-speed drilling into tough materials.
* Micro Drills: High-accuracy drills engineered for small-hole machining with precise hole diameter tolerances.
4. Forming Tools and Threading Dies
- Screw Rolling Dies: Cylindrical and flat rolling dies engineered to produce male threads on bolts, studs, and automotive components via cold metal plasticity.
- Specialty Dies: Includes spline dies, pulley dies, worm dies, and lead screw dies designed for high-volume mass production with minimal tool wear.
5. Indexable Tooling (Phoenix Series)
- Indexable Milling Cutters: Multi-use indexable milling heads and inserts engineered for heavy face milling, shoulder milling, and high-feed roughing operations in large-scale structural manufacturing.
