Gear hobbing tooling from DTR
DTR Gear-Cutting Tools – Proven Quality Across Industries
DTR (formerly Dragon Precision Tools), based in Incheon, South Korea, has been producing high-performance cutting tools since 1976. With three factories and global exports to the US, Europe, Japan, India, and beyond, DTR delivers over 3,000 hobs per month to meet the needs of customers in the automotive, aerospace, wind, mining, construction, and general engineering sectors.
DTR offers a full range of coarse to fine pitch hobs, including:
Involute gear hobs
Worm and chain sprocket hobs
Timing pulley, serration, and spline hobs
Special profile cutters
Shaper cutters and milling cutters
All tools are manufactured to AGMA, DIN, JIS, and ISO standards, with modules ranging from 0.5 to 32 and tolerances available in A, AA, and AAA grades, depending on your production needs:
- A Grade – General Purpose Use: These hobs are made to standard tolerances and are well-suited to jobbing shops, low-volume runs, or maintenance work. They provide dependable performance for less critical gear applications where basic accuracy is acceptable.
- AA Grade – High-Quality Production: Manufactured to tighter tolerances, these hobs offer improved precision and repeatability. They are ideal for medium-to-high production environments where consistent gear quality, surface finish, and tool life are important factors.
- AAA Grade – Critical Tolerance Applications: Built for the most demanding applications, these hobs meet the tightest specifications and deliver superior accuracy, minimal runout, and maximum tool life. Ideal for aerospace, defence, and precision gear production where quality cannot be compromised.
Using premium-grade steels such as M2, M35, ASP30, and ASP60, and coated with the latest wear-resistant technologies, DTR’s hobs are produced on top-tier equipment, including Reishauer CNC grinders and Klingelnberg inspection systems, to ensure unmatched tool performance and consistency.
Star SU – A Leader in Gear Tool Technology
Through the combined strength of Star Cutter Company (USA) and SAMP S.p.A., Star SU delivers one of the most comprehensive ranges of gear-cutting tools available globally. Known for their innovation and technical expertise, Star SU tools are a go-to choice for manufacturers seeking consistent quality and performance.
