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.
Application of combined threading and drill bits:
The Combined Bit is suitable for universal use in materials of medium mechanical strength, non ferrous metals and thermoplastics (up to 600 N/mm² tensile strength). It is possible with this tool to produce through threads up to a maximum threaded depth of 1xD. They are especially useful for mounting and small batch production.
