Universal HSS-E-PM drill 'GU 500' developed by a German global manufacturer with over 125 years of history.
The 'GU 500' is a powerful HSS-E-PM drill optimized for medium lot production, which could not be covered by existing small lot high-speed drills. It features excellent wear resistance due to the use of powdered high-speed steel (HSS-E-PM) and multi-layer coatings. It has a high-precision clamp with an end mill shank tolerance of h6. The unique rounded groove shape provides excellent chip evacuation. With a tip angle of 118° and a 4-facet point grind, it enables high-precision hole machining with excellent bite performance and centering capability.
Over 125 years of establishment, a German global manufacturer has developed the carbide drill 'RT 100 R' for cast iron processing.
The 'RT 100 R', optimized for machining gray cast iron and ductile cast iron, features a cutting-edge radiused point shape patented by Gooling. By shaping the corners into a radius, it excels in wear resistance and achieves a longer lifespan compared to conventional products. Additionally, it accommodates machining of relatively new materials such as CGI (Compact Graphite Iron) and ADI (Austempered Ductile Iron), which are increasingly in demand in the automotive industry. In through-hole machining, it suppresses burrs on the exit side.
"RT 100 VA" stainless steel processing carbide drill developed by a German global manufacturer with over 125 years of history ≪internal cooling specification≫
