OSG has been developing high quality and performance cutting tools to support the customers' machining operations. We propose the most efficient way of using our products to reduce the machining cost. Cost reduction at the machining operations leads to the environmental protection, because it reduces energy use.

OSG has been focusing on the research and development on eco-friendly products and machining operations. We propose dry machining, which means using no cutting oil while machining, and regrinding of tools to protect the environment.


The end mill series enable big cost reduction and production improvement by high efficient machining. OSG was awarded the Environmental Contributor Prize for the critically acclaimed environmental machining methods used by the Phoenix end mill series.

WDI coating developed specially for High Speed Steel cutting tools.Effective for high speed operations and longer tool life.
It contributes to cut down CO2.With high speed operations, cut down the operation time,with longer tool life, reduces the frequency of regrindings.
We have developed extra-long drills and taps suitable for dry and semi-dry machining.

MQL is the system to supply oil mist from the oil holes of cutting tools and minimizes the quantity of cutting oil.
OSG provides regrinding and recoating services to turn used dull tools into sharpened tools. With using the services, our customers can save the purchase cost of tools.
Also regrinding and recoating activities help to make full use of rare metals, materials of cutting tools, and reduce waste.
