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.

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.

With a taper chamfer on one threading end and a bottoming chamfer on the other, these pipe and conduit taps start threads easily and are good for threading close to the bottom of closed-end holes. The taper chamfer has 7-10 chamfered cutting threads to drive into the workpiece and start threads with less torque than other chamfer types. The bottoming chamfer has 1-2 chamfered cutting threads to create full threads near the bottom of closed-end holes. To tap threads, turn the tap with an open-end wrench or drive it at either end using an L-key or ratchet wrench. All are made of high-speed steel and are for use on most metal and plastic.

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 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.

Uncoated high-speed steel taps are for use on plastic. They have a bottoming chamfer that cuts into the workpiece with 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.

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.

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.

Use a single set for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic. Hex-shaped dies are for thread repair and can be used with conventional wrenches.

Carbon steel taps are for thread repair and occasional tapping.

High-speed steel taps and dies last longer than carbon steel when used on similar material.

Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes
