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.
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.

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.
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.

Pipe and Conduit Tap Sets
Create pipe and conduit threads in a range of hole diameters. With a square shank, these taps are compatible with tap wrenches and tap holders for drill presses and milling machines.
Taps with NPT and BSPT threads have a plug chamfer for start-to-finish thread tapping.
Carbon steel taps are for thread repair and occasional tapping.

Tap and Die Sets
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.
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
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. However, they do not start threads as easily as taper-chamfer taps. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
