With the Hikoki 780139 drill and tap combination set, you significantly speed up your metalworking tasks. Instead of switching tools repeatedly, you drill the core hole, tap the metric thread, and deburr in one single operation. This 7-piece set covers standard metric sizes from M3 to M10 with six combination tap bits. Whether you are working with steel, aluminium, or other metals during installation, maintenance, or fabrication work, you create clean, accurate threads with maximum efficiency.
