Core Products Supporting Global Manufacturing with Top Class Products and Technology OSG maintains absolute control over every aspect of its manufacturing capabilities. OSG products are produced in-house - from the production of tool material, creation of tool geometry, to the development of its own proprietary coatings - the 3 vital elements in the manufacturing of superior cutting tools. Taps Taps are used to cut screw threads on the inside surfaces of holes, creating the "female" half (nut) of the screw. High precision is of vital importance, particularly in areas such as automobile engines, which require precision screws. OSG offers a lineup of taps with diameters in various sizes and with specifications suitable for a wide variety of uses. Drills Drills are used to make holes in a wide range of surfaces. OSG has received high acclaim for the development of high-precision, high- value-added products for its use in automotive and aircraft part manufacture, which demands advanced processing techniques and zero margin of error. End Mills End Mills are used to cut and contour molds for plastic parts, which include electric home appliances, die-casting dies for automotive parts and stamping molds. To meet today's demanding requirements (smaller size, lower weight and reduced cost), OSG has developed many carbide end mills that are excellent in both processing accuracy and durability. 14 About OSG WWW.OSGTOOL.COM
