basic information
The BTA method is highly efficient, but due to the high cost of equipment, it is not economically feasible for companies to install it when the processing quantity is low. Since our company's founding in 1959, we have supported Japan's heavy industry as a pioneer of BTA tools, machinery manufacturing and sales, and BTA deep hole drilling processing. The quality of our deep hole drilling processing, based on experience and proven results, is highly regarded by customers both in Japan and abroad.

Company information
What is "BTA"? It is a question we are always asked when we mention our company name. BTA stands for "Boring & Trepanning Association." The BTA method is one of the cutting processes for creating deep holes in metal, and due to its structure, it excels in chip removal, rigidity, and productivity. As a result, it can perform high-precision deep hole machining at high speeds, and it features an excellent finish. Our company was established in 1959 with the aim of selling BTA deep hole drilling machines and tools. Since then, we have opened new factories, starting with the Kamata factory in Tokyo, to carry out BTA deep hole drilling, followed by the Sagamihara factory and the Kakogawa factory (which later moved to the Akashi factory). Additionally, we began manufacturing BTA deep hole drilling machines and tools at the Kazo factory, and our company has always been a pioneer in the BTA method.
