Use these carbon steel taps for thread repair and occasional tapping of pipe and conduit. They can tap threads into most metal and plastic, but they have a shorter tool life than standard taps.

Chip-Clearing Pipe and Conduit Thread Taps

Also known as interrupted-thread taps, these have extra space between the cutting threads, so large chips fall without packing and high amounts of lubricant can flow between the tap and the workpiece.

Pipe and Conduit Thread Taps
with Two Threading Ends

With a taper chamfer on one threading end and a bottoming chamfer on the other, these pipe and conduit taps can start threads easily, and they are able to thread close to the bottom of closed-end holes.

Combination Drill Bit/Pipe and Conduit Thread Taps

Drill and thread holes for pipe and conduit without switching tools.

Pipe and Conduit Thread Taps
for Stainless Steel and Plastic

The spiral flutes on these pipe and conduit taps keep chips clear by drawing them back out of the hole, so there's no need to reverse the tap while cutting threads.
