Seco Tools Develops Solid Carbide Drills for Aluminum Machining in Aerospace

Troy, Michigan - Seco Tools has announced the release of its new Feedmax(TM) -N family of solid carbide drills for high performance drilling in aluminum and non-ferrous materials. Developed in cooperation with manufacturers in the aerospace industry, -N drills feature a geometry that is wider and deeper than standard drills to improve chip flow and evacuation. The tools' coating has a lower silicon (Si) content to effectively machine aluminum with less than 10 percent Si, in addition to brass, zinc and magnesium. Cost savings are achieved through increased output and reliability, as well as fewer de-burring issues.

The -N geometry features a conical front clearance with a 12° relief angle and 140° point angle, with narrow land margins that are 40 percent thinner than standard drills to reduce friction and edge buildup. The drills also have an increased back taper for axial relief. Seco Tools' optimized edge preparation provides for light cutting and less stress.

For best results, -N drills should be used with Shrinkfit holders or hydraulic chucks and internal coolant. The new tools are available in diameters ranging from 0.1" - 0.551", with a 3xD drilling depth.
