Business
NS TOOL CO.,LTD. is primarily engaged in the manufacture and sale of "end mills," cutting tools mounted on machining centers to process metal and other materials. Small-diameter carbide products with blade diameters of 6mm or less account for approximately 80% of sales volume, making the company a standout specialized manufacturer focused on precision and micro-machining fields. Its main customers span a wide range of industrial sectors, including automobiles, semiconductors, electronic components, optical equipment, and medical devices. Domestically, the Sendai Plant serves as the core production base, and the company supplies products globally through its domestic sales subsidiary (G-TEC Co., Ltd.) and overseas sales subsidiaries in Hong Kong and the United States. Consolidated net sales for FY2026 (ending March 2026) were ¥9,494 million. The company is listed on the Standard Market of the Tokyo Stock Exchange.
Business Model
The company manufactures small-diameter carbide end mills using in-house-developed tool grinding machines and proprietary coating technology, supplying users through domestic and overseas agents and distributors. Under a policy of "prioritizing profit over sales," it avoids price competition through high-value-added products that pursue "differentiation" from other companies, setting a management target of an ordinary income to net sales ratio of 20% or higher. Working capital and capital expenditures are all funded through internal reserves, maintaining debt-free management.
Company Strengths
Small-diameter carbide products with a blade diameter of 6mm or less account for roughly 80% of sales volume, with End Mills (6mm or less) sales of ¥7,635 million in FY2026 (ending March 2026). The company's policy of maintaining an overwhelming range of standard products and inventory levels prevents customer attrition due to stockouts. The accumulated technical expertise and enhanced product lineup resulting from this specialization form a position that is difficult for competitors to replicate.'
The company continuously enhances the functionality of its in-house developed tool grinding machines and expands automated lines, promoting unmanned operation and labor savings. Cost reductions have been achieved through small-group improvement activities centered on the "Orange FC Activity," resulting in an ordinary income margin of 21.2% in FY2026 (ending March 2026), exceeding the company's own target of 20%. Capital expenditures remained at ¥486 million, within the range of operating cash flow (¥2,138 million).
The company maintains debt-free management, funding all working capital and capital expenditure needs from internal reserves. Against total assets of ¥19,595 million at the end of FY2026 (ending March 2026), cash and cash equivalents stood at ¥9,467 million, accounting for approximately 48% of total assets. While deteriorating asset efficiency is recognized as a financial challenge, the company's financial stability is extremely high, and even a large-scale share buyback (totaling over ¥1.3 billion) was funded entirely from internal resources.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥9,525 million in FY2022 (ended March 2022) and has since plateaued, with FY2026 (ending March 2026) revenue reaching only ¥9,494 million, up 0.7% year on year. Operating profit, however, came to ¥1,960 million (up 10.9% year on year), marking a clear reversal from the declining trend seen since FY2022 (ended March 2022). This was mainly due to a ¥215 million decrease in cost of sales year on year, supported by solid demand for semiconductors and electronic components driven by AI- and data-center-related demand, as well as robust exports to Asia including the Greater China region. As an external factor, foreign exchange losses, which had been ¥17 million in the previous period, disappeared, improving non-operating income and expenses as well. However, there is a high risk that rising tungsten prices—an external factor—will squeeze manufacturing costs in the next period, and the sustainability of the profit improvement remains uncertain.
Growth Strategy
Aiming for sustainable growth through a three-pronged approach combining continuous rollout of high-value-added products, overseas market development, and production automation
Promoting the development of highly distinctive products with an emphasis on differentiation from other companies. In FY2026 (ending March 2026), 14 new product model numbers, including standard additions, were launched to market, expanding high-value-added products such as cermet long-neck radius end mills and products for machining high-hardness steel. Improvement of new materials and coating technologies continues to be promoted.
Capturing demand related to automobiles, optics, and data centers in China and other Asian countries based on region-specific strategies. In FY2026 (ending March 2026), sales to China reached ¥1,407 million (previous period: ¥1,373 million) and sales to other regions reached ¥1,371 million (previous period: ¥1,296 million), expanding overseas sales overall. Continuing to develop the precision and micro-machining markets by leveraging sales subsidiaries in Hong Kong and the United States.
Promoting unmanned operation and labor savings through enhanced functionality of in-house developed tool grinding machines and reinforcement of automation lines. Also aiming to diversify risk by increasing production capacity at subsidiary factories. In FY2026 (ending March 2026), the synergy between mass production effects and small-group improvement activities reduced cost of sales by ¥215 million year on year, improving the operating margin from 18.7% to 20.6%.
Implementing capital efficiency improvement measures combining profit growth and capital reduction, with the goal of achieving an ROE of 10%, exceeding the consolidated cost of capital of 8.6%. In FY2026 (ending March 2026), share buybacks totaling over ¥1.3 billion were carried out, improving ROE from 7.1% in the previous period to 8.0%. Although the target has not yet been achieved, the improving trend continues.
