Suitable for extensive buffing and polishing! Bias cotton buff with pleats formed.

■For catalog downloads and inquiries, please visit the URL below and click on "Request Materials Here." http://www.koyo-sha.co.jp/ This is a buff with a thickness of 12 to 16 mm, made by gathering bias-cut cotton fabric into numerous pleats and securing the center with a metal fitting. While the number of cotton layers is 16 plies, the greater the number of pleats, the higher the rigidity. It is graded into five levels (M-0, 2, 4, 6, 8) ranging from the softness equivalent to loose cotton buffs to the hardness equivalent to spiral cotton buffs. For selection in the polishing process, M-4 to 8 is used for coarse and medium polishing, while M-0 to 2 is used for finishing polishing. 【Features】 ○ Long lifespan due to the bias structure. ○ Air is expelled from the center to the periphery, providing a cooling effect. ○ The pleated surface results in a larger buff surface area, enhancing abrasive retention performance. ○ Available in versions using M fabric and C fabric.

Amazing polishing power! Experience the shine recognized by professionals with this sisal buff for disc grinders.

■For catalog downloads and inquiries, please visit the following URL and click on "Request Materials" below. http://www.koyo-sha.co.jp/ 【Features】 It has greater polishing power than conventional portable polishing tools because it can polish at high speeds. Being a unit type, it has good compatibility with the workpiece, and at the same time, the buff surface is less likely to clump, providing stable polishing effects. By selecting the appropriate buff polishing agent, it is possible to achieve a rough polish that removes #240 grit marks, up to a polishing finish equivalent to #400 grit. ○ After using the offset sisal, using the offset felt will yield outstanding gloss.

Nitto Kohki will hold the "2025 Attack Fair in Meiko" for two days from July 23 (Wednesday) to July 24 (Thursday), 2025, at the "Kowa Seminar Plaza 2F Training Room NO.12 (inside Kowa Sports Land)." The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful souvenirs for attendees and many fun activities planned. We look forward to welcoming everyone!

On August 4, 2026 (Tuesday), we exhibited at "Wellness Food Japan 2026" held at Tokyo Big Sight. We would like to express our heartfelt gratitude to all the visitors who attended. The products and services that particularly attracted attention at the exhibition are as follows: 1. No shaker needed? "Protein Spout Pouch" At the venue, we showcased a "shaker style" display inspired by protein and supplements. Due to its convenience for portioning, portability, and ease of use, we received numerous inquiries such as, "We want to create a pouch for easy protein consumption" and "We want to switch from existing aluminum pouches." 2. High light-blocking pouch that can pass through metal detectors "ZEKKO Series" "We want to conduct foreign matter inspections with metal detectors for all products before shipping. However, we have no choice but to use aluminum pouches because the ingredients are sensitive to light and oxygen..." We heard many such concerns regarding quality control and product development at the venue. Our proposed "ZEKKO Series," which does not use aluminum at all while maintaining excellent light-blocking and barrier properties, garnered significant interest from many attendees.

[Speaker] Accenture Ltd. Managing Director, Industry and Enterprise, Yoshiyuki Fujino Principal Director, Digital Core, Strategy, Akihito Masuda [Key Lecture Content] With the rapid spread of AI, the infrastructure supporting urban competitiveness is transitioning from physical foundations such as roads and water supply and sewage systems to a "Watt-Bit Collaboration" that integrates computation (bits), power (watts), and communication into a single design. The idea of placing data centers in areas with surplus power and delivering only the results as bits redefines the location of data centers, power systems, communication networks, and even urban and regional development, fundamentally changing the design philosophy of social infrastructure. This lecture will explain the role that private companies can play and the strategies for achieving this, taking into account overseas leading examples. [Lecture Items] 1. Watt-Bit Collaboration - The Core of Urban Infrastructure Reorganization 2. The Significance of Integrating Computation, Power, and Communication in Three Layers 3. The Speed of Change Observed in Overseas Leading Examples 4. Changes in Collaboration with Government Agencies and Local Governments 5. The Next Move for Private Companies - Points of Strategic Shift 6. Q&A / Business Card Exchange

[Lecturer] Anderson Mori & Tomotsune Foreign Law Joint Enterprise Partner Attorney Fumiya Utagawa [Key Lecture Content] Thermal power generation occupies an important position for ensuring stable electricity supply, but there is also a social demand for decarbonization. In addition to the establishment and replacement of LNG-fired power plants, the utilization of hydrogen and ammonia as fuels and the application of CCS are also anticipated. Recently, there have been revisions to the system in preparation for the fourth round of the long-term decarbonized power source auction and the full implementation of the CCS Business Act. In this lecture, the instructor, who has been involved in the Japanese government's policies at the Agency for Natural Resources and Energy until June of this year, will explain the challenges and considerations in project formation, focusing on the utilization of hydrogen, ammonia, and CCS. [Lecture Items] 1. Overview of policy trends regarding decarbonized thermal power 2. System revisions for the fourth round of the long-term decarbonized power source auction 3. Introduction of preliminary examination based on the Hydrogen Society Promotion Act 4. Full implementation of the CCS Business Act 5. Considerations for project formation 6. Q&A / Business card exchange
