SANDVIK Coromant has released a drill for heat resistant super alloy (HRSA) machining in aerospace applications.According to the company, the CoroDrill Delta-C R846 can continuously and reliably produce holes in demanding HRSA materials, which place heavy demands on the cutting edge.The drill’s geometry is said to be optimised for maximum efficiency in repeat short hole drilling. The cutting edge has a more consistent curve to add strength to the outer corners, in order to counter high cutting forces.A deep flute shape on the drill body optimises chip removal from the cutting zone, in order to preserve the integrity of the component surface.The company claims this distributes the cutting forces evenly over the cutting edge to evenly wear the drill without sudden changes. This improves the tool life.The standard CoroDrill Delta-C line has tools for three to 12mm diameters.Key contact:Sandvik Coromantorder-australia.coromant@sandvik.com
