    Pipe and Conduit Drill Taps

    Image of Product. Front orientation. Drill Taps. Pipe and Conduit Drill Taps.
    Drill and thread holes for pipe and conduit without switching tools. Made of uncoated high-speed steel, these tools are for use on most metal and plastic. Their right-hand spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping of through holes.
