General Purpose Taps
Cut threads into 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. For better chip flow, choose a tap with fewer flutes.
Drive square-shank taps with a tap wrench or use them in a tap holder for drill presses and milling machines. Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. 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 chamfers. 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.
Sets include one taper-, one plug-, and one bottoming-chamfer tap.

Left-Hand General Purpose Taps
Tap threads for left-hand threaded fasteners. Made of uncoated high-speed steel, these taps are durable enough for small-scale tapping jobs, but they're not recommended for production use. All have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.

Economy Carbon Steel Taps
Often used for thread repair and occasional hand tapping, these carbon steel taps can thread holes in most metal and plastic, but they have a shorter tool life than standard taps.
Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. This lets them cut with 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 start threads less easily than taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Chip-Clearing Taps for Through Holes
Keep chips clear while tapping. Also known as gun taps, these have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. They're made of high-speed steel 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 plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. Taps with a black-oxide finish cut with less friction than uncoated taps.

Taps for Steel and Stainless Steel
These taps are made of high-speed steel for higher strength and wear resistance than standard taps. Their flutes are designed to keep chips clear, so they don't need to be reversed to prevent buildup. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. Taps with plug chamfers have 3-5 chamfered cutting threads. Taps with bottoming chamfers have 1-2 threads.
Taps for through-hole threading have spiral-point flutes, which push chips ahead of the tap and out of through holes. They're also known as gun taps.

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. 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.

Acme and Metric Trapezoidal Thread Taps
Form general purpose Acme threads. These high-speed steel taps are for use on most metal and plastic. With a square shank, they're compatible with tap holders for drill presses and milling machines. Also known as tandem taps, these have an extended chamfer with two sets of chamfered cutting threads. Because these sets of threads have different shapes, reversing the tap for removal may cause damage to the workpiece and is not recommended. Use these taps with a rigid setup to tap through holes only.
Metric trapezoidal threads are similar to Acme threads.
