サイトウ製作所 Company Profile

The ultra-hard small diameter drill is ATOM. Including end mills, the size lineup consists of approximately 7,000 items! We also accommodate special tools.

Our company was established in 1934 as the first factory in Japan specializing in the manufacture of metal cutting saw blades. Since then, we have inherited the spirit of development cultivated at the time of our founding and have continuously challenged ourselves with new technologies and processing methods. In 1954, we began manufacturing carbide precision cutting tools, pioneering a new field in cutting processing, and we have become unmatched in the world of micro-diameter tools. The knife-making technology developed by ATOM continues to evolve, and our refined know-how has made the sub-micron world possible. All of us at ATOM stand at the origin of "manufacturing," pouring our soul and sincerity into each tool as we continue to produce precision cutting tools.
