NAGAOKA, once a watch bearing manufacturer, has grown to become one of the finest hard-to-cut materials-processing specialists in the world. Our flagship product is the Nagaoka stylus that is loved by classic phonograph fans.

As the main manufacturer of this kind in Japan, we produce diamond styli. The machining process involves first joining a diamond to a metallic titanium shank in a vacuum deposition furnace, then polishing the diamond to a circular cone and shaping the tip to a radius of 15 microns.

The Nagaoka range of audio accessories offer the same quality and attention to detail as the Nagaoka stylus range.
