Economy Carbon Steel Pipe and Conduit Thread Taps
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. 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. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
