Sandvik Coromant aims to reduce cost per hole in steel with CoroDrill 860

Available in lengths 3-8XD as standard, the company describes CoroDrill 860 as a high performance drill that can be applied to a wide range of hole making tasks. For instance, aside from conventional drilling and stack drilling, it can produce chamfered holes and cross-holes, as well as holes through inclined or convex/concave surfaces. The CoroDrill 860 provides an optimised cutting edge geometry and flute shape for effective chip clearance, particularly at increased rates of penetration. This is demonstrated when using high cutting data in long and short chipping materials. Its consistently problem-free performance results in both superior hole quality and tool life, says the company. A further benefit, says Sandvik Coromant, is that the lower cutting forces mean fewer problems when weak fixtures or thin-walled components are involved.
