Whether in the machining of injection nozzles for vehicles or in the production of molds for the smallest injection-molded components - machining in the micro range is in demand for many applications.

Mapal has expanded its range of solid carbide drills for steel machining in order to offer the right tool for these machining operations. Users can use the new Micro-Drill-Steel series for the diameter range from 1.0 to 2.9 mm with internal cooling at drilling depths of 5xD, 8xD and 12xD. Four guide chamfers ensure the best guiding properties. The tool experts have developed the geometry specifically for the efficient and economical machining of very small holes in steel.

The flute shape with tapered core ensures ideal chip evacuation even with tough steel materials. Maximum performance and tool life are guaranteed thanks to the new combination of cutting materials and specially adapted micro-geometries.
