Tap left-hand threads for pipe and conduit. For use on most metal and plastic, these high-speed steel taps are durable enough for small-scale tapping jobs, but they're not recommended for production use. The square shank is 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.

Also known as short-projection taps, these have fewer tapered threads at the tip than standard pipe taps, so you don't have to drive them as deep to produce full threads. They're made of high-speed steel and are for use on most metal and plastic. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a bottoming chamfer with 1-2 chamfered cutting threads, so they can thread close to the bottom of closed-end holes.

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. Made of uncoated high-speed steel, these taps are for use on most metal and plastic. Their square shank is 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.

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.

The cutting teeth are shaped to cut smooth threads in soft pipe and conduit material. With a square shank, these taps are compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 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.
