Read Co., Ltd.

Our self-developed diamond tools have a presence in the market. 

We are a diamond tool manufacturer established in 1973. Our company has developed various original products based on reliable precision machining techniques and extensive experience and know-how. Our products include electroplated diamond wires (machining is faster by five to ten times than with the loose abrasive method), and ceramic cutting blades (minimum thickness is 30 µMT). This is increasing our presence in the industry. Our other lines of business include precision grinding and machining whetstone manufacturing and sales. We have been involved in joint R&D projects with public research institutions, including the National Institute of Advanced Industrial Science and Technology (AIST) and Japan Science and Technology Agency (JST).


Other presentation

[Company strength]
Our company applies our original technologies to develop, manufacture, and distribute various precision machining and cutting whetstones and electroplated diamond wires. We quickly respond to various customer needs regarding quality, delivery, after-sales service and other matters. A specialist on the topic always responds to customer inquiries, from development to after-sales service. We acquired ISO 9001 and ISO 14001 certification as part of our corporate activities. We have started to promote environmental measures in addition to product quality management, as these measures are have been becoming increasingly important in recent years.

[Business description]
Our company was established in 1973 as a diamond tool developer, manufacturer, and distributor and provider of ultra-precision machining services. Our company’s motto is simply “What’s next?” This implies that we should commit ourselves to realizing our corporate vision, policy, desires, and dreams. We accelerated global expansion to support technological innovation for manufacturers around the world when we entered the then-unknown field of ultra-precision diamond whetstone machining (for magnetic heads). This effort helped us become a pioneer and a leading company in the field. We now have a share of around 80% of the global whetstone market for machining magnetic heads. 

Manufacturing (various diamond tool manufacturing and sales)

[Strength of products/technologies]
Our company is committed to product development by making the most of our original technologies and development technologies, under quality management that satisfies requirements in the world’s most advanced field. This is based on creativity, the latest technologies, our know-how from nano-level precision machining, and a customer service mindset. We already have quality policies in place to realize the highest quality level. Our plants have already acquired ISO certification (ISO 9001:2000) and have established an across-the-board quality management program. We will make improvements every day under the philosophy that our company is all about quality, and we will not be complacent about quality. We possess Japan’s best manufacturing methods for ceramic cutting blades (minimum thickness, 30 µMT) and electroplated diamond wire (machining five to ten times faster compared to the loose abrasive method). 

[Representative's message]
All our divisions will take up the challenge of entering the global market, and not only the sales department. We must overcome all the obstacles in the global standards, laws, regulations, frameworks, customs, and cultures to appeal to both domestic and overseas companies. We plan to expand globally by actively increasing our expatriate staff, developing human resources, and improving technologies and services. 

[Company structure for market development/overseas expansion]
We usually suggest a single integrated manufacturing process that covers both upstream and downstream processes when we manufacture for a customer. We intend to enhance our technical support and listen to our customer’s voices. This will be done by making use of the sales forces and engineers in our domestic Japanese and overseas sites.

[Market share/Ranking]
We have an 80% share (largest share) of the market for cutting blades for magnetic head sliders,
and a 22% share (second-largest) for diamond wire for slicing solar panel wafers.
