Seco Tools’ Feedmax -N solid carbide drills are designed for high-performance drilling in aluminum and nonferrous materials. The drills feature a geometry that is wider and deeper than standard drills to improve chip flow and evacuation. The tools are available in diameters ranging from 0.1" to 0.551" with a 3×D drilling depth.
The drills’ coating has a lower silicon (Si) content to effectively machine aluminum with less than 10 percent Si, as well as brass, zinc and magnesium. According to the company, the tools achieve increased output and reliability as well as fewer deburring issues. The geometry features a conical front clearance with a 12-degree relief angle and 140-degree point angle, with narrow land margins that are thinner than standard drills to reduce friction and edge buildup. The drills also have an increased back taper for axial relief. The inserts’ edge preparation provides for light cutting and less stress.
