Taps are cutting tools used to create internal threads, allowing you to fasten bolts and screws securely into materials like metal, plastic, and wood. They are commonly used in engineering, plumbing, crafting, and various household tasks. Selecting the right type of tap is crucial for ensuring strong and accurate threading.
Understanding what are the 3 types of taps can enhance your hand tool collection and improve your project outcomes. Here’s a detailed look at each type:
Hand Taps
Hand taps are the most versatile and commonly used taps for threading. Typically made from high-speed steel, these taps can be used manually by hand or with a tap wrench. Hand taps come in sets of three: taper, plug, and bottoming taps.
Taper Taps: These have a tapered end, making it easier to start threading, especially in blind holes. They create a gradual entry, reducing the risk of cross-threading.
Plug Taps: With a less tapered design, plug taps are effective for creating threads all the way to the bottom of a hole. They can be used for both through holes and blind holes.
Bottoming Taps: Designed for threading all the way to the bottom of blind holes, these taps have a flat end, allowing for maximum thread depth.
Example Usage: If you're working on a project that requires creating threads in a metal block, a taper tap would be suitable for easy start, while a bottoming tap can finish the job.
Machine Taps
Machine taps are designed for use in machinery and are often powered by drilling machines. They are faster and more efficient than hand taps, making them ideal for production work.
Spiral Flute Taps: These have flutes that spiral up the tap's body, helping to efficiently remove chips and prevent clogging, making them best for through holes.
Straight Flute Taps: With straight, parallel flutes, these taps are used in blind holes and are more suited to tapping softer materials.

Example Usage: If you’re in a factory setting tapping multiple metal pieces, a spiral flute machine tap could significantly speed up your processes.
Specialty Taps
Specialty taps are designed for specific applications or materials. This category can include taps for use with hard metals, plastics, or even specialized threading measurements. Some common types include:
Pipe Taps: For creating threads in pipes, these taps usually follow a standard measurement to ensure fitment.
Form Taps: Instead of cutting away material to create threads, form taps displace it, resulting in stronger threads in softer materials.
Example Usage: When dealing with PVC piping in plumbing work, a pipe tap will ensure the threads fit perfectly without leakage.
When selecting a tap, consider the following factors:
Material: Choose taps based on the material you are working with. Higher-speed steels work well for metals, while specialty taps may be required for plastics.
Depth of Thread: Determine whether you need a blind hole or through hole, as this impacts your tap choice.
Ease of Use: For manual projects, hand taps can be more user-friendly, especially for beginners.
Understanding what are the 3 types of taps—hand taps, machine taps, and specialty taps—enables you to choose the right tool for your threading needs. Knowing when to use each type can save you time and improve the quality of your work.
If you're considering starting a new project that requires threading, take a moment to evaluate the materials and tasks ahead of you. With the right tap in hand, you’ll find your projects will go smoother and yield better results.
