Indexable inserts
Drilling operations in aluminum
Sandvik Coromant has developed CVD-coated indexable inserts. The extremely hard properties of the diamond coating are said to offer a long tool life and, in combination with an innovative chip breaker and geometry design, ensure outstanding drilling performance in demanding materials such as aluminum. The diamond-coated insert grades GCN124 and GCN134 have been designed to deliver the lowest cost per hole when machining most ISO-N materials - thanks to a long tool life and/or higher productivity. The latter results from higher cutting data and minimized downtimes due to fewer insert changes.
Other advantages include easy handling thanks to high reliability and longer tool life as well as improved surface quality in the drill hole due to the ability to counteract built-up edge and lubrication effects. Reduced insert consumption reduces both stock levels and environmental impact. sw
