"Grease flows down with the coolant." "I'm concerned about the sticking of the chuck part." "I want to reduce the burden of lubrication work." In response to these lubrication challenges in machine tools, the Idemitsu Kosan booth at JIMTOF2026 will showcase Idemitsu NTG's grease "Kingstar EP No.1/No.2." ■ Featured Product "Kingstar EP" This grease is formulated with organic molybdenum and special polymers, providing excellent adhesion, water resistance, and extreme pressure properties. - It adheres firmly to the lubrication surface, suppressing grease scattering and leakage. - It contributes to reducing grease contamination in the coolant. - It supports the lubrication of the chuck part, helping to maintain stable tool gripping force. - It proposes a reduction in maintenance work by extending the lubrication interval. *Effects may vary depending on usage conditions. Why not start addressing the selection of grease to ensure stable operation of machine tools and review maintenance work? Please feel free to consult us about the product features and applications at our booth. ■ Event Overview Date: October 26 (Monday) to October 31 (Saturday), 2026 Venue: Tokyo Big Sight (Tokyo International Exhibition Center) Our Booth: West Hall 4 W4092 We sincerely look forward to your visit.

Thank you for your continued support. Our long-term rust preventive oil, "Idemitsu Supercoat RS," which achieves improved productivity through water displacement, has recently won the 2025 "Outstanding New Product Award" at the Industrial Cleaning Conference (JICC). This oil successfully combines water displacement (cleaning properties of cutting fluids and grinding fluids) and exposure rust prevention at a high level, which was previously difficult to achieve. Users have praised it for significantly reducing rust, stains, and white residue during rust prevention storage, and for allowing cleaning and rust prevention processes to be done with a single liquid. This recognition is a result of our contribution to the industrial cleaning industry and the technical uniqueness of our product. For those struggling with rust prevention issues between processes, or considering yield improvement and quality enhancement, we encourage you to consider "Idemitsu Supercoat RS" at this opportunity.
