Taps
![]() |
Cut threads into holes so screws, bolts, and rods fit snugly. Our basic taps have straight flutes that are good for most jobs.
High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
Carbon Steel—The economical choice for occasional hand tapping. These work on most metals and plastic but will dull more quickly than other taps.
Uncoated—The economical choice, these won't last as long as coated taps.
Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.
Plug Chamfer—These taps thread through holes and blind holes. The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, they're easier to turn than bottoming taps but require more force than taper taps.
Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.
Number of Flutes—Taps with fewer flutes have more space to capture chips, so you won’t have to clear them as often. However, they can be more difficult to keep straight in the hole.
Taps Sold as Sets—Include one tap of each chamfer type.

Chip-Clearing Taps
Remove long, stringy chips to produce cleaner threads than standard taps. The flute design prevents buildup to protect the quality of the threads and avoid damage to the tap. Since you don’t need to reverse these taps to extract chips, they also form threads faster.

Spiral-Point Flute for Through Holes |
The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.
Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun taps.

Trapezoidal Thread Taps
![]() |
The metric version of Acme thread taps. These cut the broad threads found on lead screw nuts, linear actuators, vises, and other moving components. They have two sets of chamfered threads: the first for cutting a rough profile and the second for finishing it. They’re only for through holes since the two different chamfers can damage the workpiece if you reverse the tap. Once done threading, release the tap from the holder and remove it from the other side of the hole. Also known as tandem taps.

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.
Carbon Steel—Carbon steel taps are for thread repair and occasional tapping.
Plug Chamfer—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.
Taper Chamfer—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.
Hex—Hex-shaped dies are for thread repair and can be used with conventional wrenches.
