Sandvik Coromant Co. Drills For Composites CoroDrill 854/856

Producing holes in high-resin materials, with increasing demands on delamination and splintering, can be optimized with the drill geometry design. The CoroDrill geometries is designed to improve hole entrance and exit quality on carbon fiber materials with high fiber content. Benefits Excellent hole quality and surface finish Reduced risk for delamination and splintering Reduced burr formation on exit in aluminum materials (CD854) Features CoroDrill 854: Point geometry designed to prevent splintering and fraying CoroDrill 856: Design to reduce delamination problems Diamond coating (N2OC) Available as standard stocked items 4-12.7 mm (0.157-0.500 inch) as well as engineered solutions.
