Indexable drills have long been known for their cost-efficiency—but lower price tags often come at the expense of accuracy and hole quality. The CoroDrill® 880 solves this problem with unique insert geometries and a configuration that creates a balanced, step-by-step entrance into the workpiece. This reduces cutting forces to less than half of typical insert drills, and virtually eliminates deflection on entry.
CoroDrill® 880 range features indexable insert drills from 12 to 84 mm (0.472-3.307 inch) in diameters, as well as engineered solution to 129 mm (5.078 inch). Products are available in two different designs to cover different diameter ranges.
