Combination Drill Tap

The Combination drill tap has been designed for drilling, tapping, or deburring in one operation using battery-powered screwdriver drills and electric hand drills. Still, they are also suitable for thread cutting in a stationary drilling machine.

They are very popular due to the vastly reduced time to drill and tap a hole versus conventional taps that require pre-drilling. Combi drill taps are great for thin soft materials such as aluminum and steel sheet or conduit. Only suitable for through holes. 

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.
