Types of Taps

When it comes to taps, there are several different types to choose from. Each type has its own unique characteristics and is designed for specific applications. Let’s take a closer look at some of the most commonly used taps:

Straight Flute Taps

Straight flute taps, also known as hand taps, are the most basic type of tap. They have a straight flute design with sharp cutting edges. These taps are commonly used for general-purpose threading in softer materials like aluminum or brass. Straight flute taps are easy to use and suitable for both hand and machine tapping.

Spiral Flute Taps

Spiral flute taps, also known as machine taps, have a spiral flute design that helps to evacuate chips from the hole while tapping. This design reduces the risk of chip clogging and ensures smooth and efficient threading. Spiral flute taps are ideal for machine tapping in materials with long chips, such as steel or cast iron.

Taper Taps

Taper taps have a tapered design with gradually increasing diameter along the length of the tap. These taps are used to start the threading process and create a gradually deeper hole. Taper taps are commonly used in applications where the hole needs to be threaded all the way through the material.

Plug Taps

Plug taps, also known as intermediate taps, have a straight fluted design with a chamfer at the tip. These taps are used to continue the threading process after the taper tap. Plug taps are suitable for through-hole threading or blind-hole threading where the hole does not go all the way through the material.

Bottoming Taps

Bottoming taps, also known as finishing taps, have a shorter flute length compared to other taps. These taps are used to thread the bottom of blind holes or holes that do not go all the way through the material. Bottoming taps have a flat or slightly concave tip that creates a full thread profile in the hole.

Choosing the Right Type of Tap

When choosing the right type of tap, there are several factors to consider. Here are some important points to keep in mind:

Material

The type of material you are working with plays a significant role in determining the appropriate tap. Different materials have different hardness levels, chip characteristics, and cutting requirements. For example, a spiral flute tap is more suitable for threading in steel, while a straight flute tap works well with softer materials like aluminum.

Thread Type

Consider the type of thread you need to create. Taps come in various thread forms, such as metric, UNC, or UNF. Ensure that the tap you choose matches the desired thread type and pitch.

Depth of Hole

The depth of the hole you need to thread is another crucial factor. If you are creating a through-hole, a taper tap followed by a plug tap may be sufficient. However, for blind holes, you may need to use a bottoming tap to ensure proper threading at the bottom.

Tapping Method

Consider whether you will be hand tapping or using a machine for the threading process. Some taps are specifically designed for hand tapping, while others are more suitable for machine tapping. Ensure that the tap you choose matches your preferred tapping method.

Quality

Lastly, consider the quality of the tap. Higher-quality taps are made from durable materials and undergo precision manufacturing processes, resulting in sharper cutting edges and longer tool life. Investing in a high-quality tap can save you time and effort in the long run.
