OSG also offers an extensive line of High Technology cutting tools designed for use in today's most aggressive conditions. These premium tools feature exclusive metallurgy, cutting geometries and unique surface treatments. The surface treatments help to increase productivity, reliability, and tool life while reducing machining time, scrap, and down time. OSG also offers a complete line of thread-rolling, flat, cylindrical, planetary, and trim dies which are made of the best available die steel in the world. Special tool steels are also used. More than 700 styles and sizes are available for immediate delivery. Since 1981, more than $200,000,000 has been reinvested into developing advanced cutting tool technology. The company's advancements in cutting tool design and production have produced very high quality tools that are setting new standards for productivity and performance in the cutting of alloys, stainless steels, and exotic space-age materials. As part of this commitment to quality, OSG machines over three miles of material and removes over two tons of material per month in the testing of end mills alone. The commitment to quality includes a bank of CNC machining centers maintained for the single purpose of testing end mills. Through these facilities and our corporate commitment to excellence, we are able to continuously refine our cutting tool technology, improve product quality, and reduce cost to our customers, while at the same time preserving the environment.
