The Coro Drill 880 series features indexable blade drills 12-84 mm (0.472-3.307 inches) in diameter and custom solutions for 129mm (5.078 inches). There are two different designs covering different diameters. Indexable bits have long been known for their cost-effectiveness, but low prices often come at the expense of accuracy and hole quality. The Coro Drill 880 has a unique blade groove configuration that solves this problem by ensuring smooth access to the workpiece. Compared with the typical blade bit, it reduces the cutting force by half and eliminates the deflection at the entrance.
