Emuge Corp.’s EF-C carbide step drill program features drill-chamfer tools. Users can select from a range of stock sizes, including the ability to order customized lengths.
The step drill program is a high-penetration rate solid carbide drill that drills and chamfers in one operation, saving time and providing a more accurate hole-to-chamfer location and hole preparation for tapping or thread milling. Tools feature a double margin design on the minor diameter for the roundest threaded hole size, and the web construction is adjusted for each diameter for maximum chip evacuation efficiency.
The program includes an extensive range of sizes from 2.8 mm to 15.5 mm minor diameter, UNC/UNF (No.6-32 to 5/8”-11”, M/MF (M3 to M18), and a full size range in 2XD and 3.5XD lengths. Tools are coolant-through, four-margin design with TiAIN-T14 coating, can cut a range of materials and are available in cut or form thread diameters.
