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.
★ Strong drill body and high rigidity tool holder interface can ensure safe and reliable drilling
★ The chip groove is designed with spiral angle, and the blade groove is optimized for all materials, so the excellent chip control and chip removal effect can be achieved.
★ Excellent flexibility-replaceable fixed tool holder system ensures one drill body for 5 diameters
★ Easy to use economical solution with commutative tool holder and indexable blade
