Oh So Green

At OSG it is about more than just growing. It is also about growing responsibly, by being actively mindful of the environment and any means by which we can improve it.


This is why we strive to produce tools that are more environmentally friendly, such as coolant-fed drills and taps designed to perform with MQL (Minimum Quantity Lubrication), so coolant waste can be reduced from gallons to ounces.


By voluntarily attaining the ISO 14001 certification, we certify annually OSG's on-going commitment to reducing the impact our manufacturing facilities have on the environment. As of 2009, our 4 largest factories recycle 99.9% of all materials and liquids used in manufacturing.


While our name represents the Osawa family, we don't mind if people mistake our initials for an "Oh So Green" company.
