Brands
Established in 1976, 7-HERO Industrial Co., Ltd. owns its own brand, specializing in high-quality, high-precision hardware and CNC lathe tool accessories. These include: tungsten carbide fixed ejector pins (accuracy within 0.002mm), tungsten carbide anti-vibration tool holders (capable of deep hole machining up to 7 times the diameter), internal and external diameter grooving tool holders (compatible with inserts from major global brands), tungsten carbide precision boring tool holders (an excellent aid for deep hole machining in mold bases), and the new brand "ADONAI" series of turning tools. The products are diverse and complete, boasting excellent rigidity, toughness, and wear resistance! Unique tool tip and support designs enhance vibration resistance and chip removal, reducing tool holder wear. Professional and attentive tool matching services solve customers' cutting difficulties. Furthermore, OEM services are also available!
Brand Features
Regarding the "ADONAI" series of knurling cutters, a new brand under CHU SHANG Industrial Co., Ltd., this is a high-end product line that combines nearly half a century of manufacturing experience with modern cutting technology.
The following is a detailed introduction to this series:
Technical Highlights of ADONAI Lathe Tool Series
- Exceptional vibration resistance and stability: The ADONAI series features a unique tool head and support structure design. This design effectively absorbs vibrations during machining, ensuring clear and uniform patterns even at high speeds, without ghosting, and extending the life of the tool holder and machine spindle.
- Ultimate chip removal: Turning often results in surface scratches due to chip buildup. ADONAI tools have optimized the chip removal space to reduce heat accumulation and tool wear, making them suitable for long-term automated production.
- Material rigidity and wear resistance: Continuing the advantages of the main industry in tungsten steel processing, ADONAI tool holders have excellent rigidity and toughness, and can maintain excellent processing accuracy even when facing high hardness materials such as stainless steel.


Brand Background and Core Values
Since its establishment in 1976, Zhushang Industrial Co., Ltd. has been renowned in the field of precision hardware and CNC lathe parts under the "7-HERO" brand. To meet the high standards of global manufacturing for workpiece aesthetics and anti-slip performance, it launched the new brand "ADONAI". This brand focuses on the research and development of embossing tools, aiming to provide more stable and refined embossing solutions than traditional machining methods, meeting the needs of aerospace, medical, precision electronics, and high-end parts processing.
Product diversity and applications
This series offers a variety of pattern options, including straight weave, cross weave (grid), and twill weave, and is compatible with standard blades from major global brands. Its applications are wide-ranging.
- Functionality: such as non-slip texture on hand tool handles and knobs.
- Decorative: Refined aesthetics of high-end consumer electronics and watch parts.
- Specialized solutions: We offer specialized tooling services for deep holes or small workpieces.
Summarize
ADONAI is more than just a new brand; it represents the determination of Taiwan's manufacturing industry to shift towards "high value." By combining it with the existing tungsten steel anti-vibration technology of Chi-Shang Industrial Co., Ltd., the ADONAI turning tool series solves the problems of vibration and insufficient precision commonly found in past machining processes, making it an ideal choice for those seeking perfect workpiece surface treatment.
