    Whether in the machining of injection nozzles for vehicles or in the production of moulds for the smallest injection moulding components – machining in the micro range is a challenge with numerous applications.

    MAPAL has expanded its range of solid carbide drills for steel machining to offer the correct tool for these machining operations. The new MICRO-Drill series is now available for diameters from 1.0 to 2.9mm with internal coolant. This allows users to drill at depths of 5xD, 8xD and 12xD. Four guiding chamfers ensure the best guiding properties and the MAPAL experts have developed the geometry especially for the efficient and economical machining of very small bores in steel.

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