VÖLKEL-Combined-Bits have been designed for drilling, tapping and
deburring in one operation using battery-powered screwdriver drills and
electric hand drills with right-hand and left-hand rotation, but they are
also suitable for thread cutting in a stationary drilling machine. The
Combined Bit is suitable for universal use in materials of medium
mechanical strength, non ferrous metals and thermoplastics (up to 600 Nm² tensile strength). It is possible with this tool to produce through
threads up to a maximum threaded depth of 1 x D. They are especially usefull for mounting an dsmall batch production. Take care that the tool and the axis of the
hole are exactly aligned and use a suitable cutting oil.
