Sandvik Coromant, a global leader in metal cutting solutions, has unveiled its latest innovation, the CoroDrill® 860 with -SD geometry, a solid carbide drill designed specifically for drilling in nickel-based Heat-Resistant Super Alloys (HRSA) materials. This new drill offers exceptional drilling depth capabilities of up to 8 times the drill diameter (8×D) and is set to become a trusted tool in industries with stringent quality and performance requirements, such as aerospace.
In industries like aerospace, the demand for drilling nickel-alloy aero-engine components is critical, with a strong emphasis on process security and achieving maximum tool life. Current drilling strategies often fall short of meeting these demands, leading to compromised tool life and process stability. However, the CoroDrill® 860 with -SD geometry has been purpose-designed to excel in machining nickel alloys, providing consistent and predictable tool life while ensuring high hole integrity.
One of the key elements contributing to the drill’s outstanding performance is its unique grade, S2BM. This grade combines a fine-grained cemented carbide substrate with a multi-layer PVD coating and post-treatment, resulting in maximum tool life. The drill’s geometry includes optimized clearance angles, precise edge preparation, flute shape, corner chamfer, and a double margin, all of which work in harmony to deliver superior performance and process security.
Extensive design development and rigorous testing in various HRSA materials have confirmed the CoroDrill® 860 with -SD geometry’s consistency and reliability, even in drilling applications with depths of 3, 5, and 8 times the drill diameter. This level of performance stability enhances process planning and cost calculations, allowing for more accurate tool life predictions and cost-per-part analyses.
Robert Smith, Offer Manager for Hole Making and Composites at Sandvik Coromant, emphasized the drill’s reliability and performance, stating, “CoroDrill® 860 with -SD geometry is a reliable drill that guarantees the highest performance and process security in heat-resistant superalloys.” For industries that demand precision, longevity, and cost-effectiveness, the CoroDrill® 860 with -SD geometry stands as the drill of choice for high-value components, helping to reduce the cost per hole and per component while ensuring uncompromised quality. Trust in the CoroDrill® 860 with -SD geometry for all your drilling needs in nickel-based HRSA materials, and experience the highest levels of tool life and process security.
