Pipe and Conduit Thread Taps
Create threads sized 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. They have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.
Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
Bottoming-chamfer taps cut into the workpiece with just 1-2 chamfered threads. This short chamfer lets them thread holes closer to the bottom than other taps, but they require more torque to start threads.

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. 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.

Combination Drill Bit/Pipe and Conduit Thread 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.

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. All have a square shank, so they're compatible with tap wrenches and tap holders for drill presses and milling machines.
Titanium-nitride (TiN) coated cobalt steel taps can cut threads in plastic and stainless steel. They resist heat and wear better than high-speed steel taps, letting them last up to twice as long. All have a plug chamfer with 3-5 chamfered cutting threads, so they require moderate torque and are good for start-to-finish tapping.

Pipe and Conduit Thread Taps for Aluminum, Copper, and Brass
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.
