Insight into Tapping tools: Understanding the Structure and Classifications for Mechanical Applications

In the field of mechanical engineering, the terms "tapping" and "tap" are widely recognized. However, distinguishing between these concepts often leads to confusion.

Tapping refers to the process of creating threads and is commonly used for this purpose. Currently, taps are utilized for producing external threads or creating internal hole threads. Therefore, a tap is considered a tool, while tapping is categorized as an operation within the context of the technological process.

1. Tapping Tool Classification

Various methods are used to categorize tapping tools, with the most common approach being based on the following criteria:

1.1 Based on the Processing Method

Tapping tools can be classified into two main types based on the processing method: machine taps and hand taps.

Machine tapping involves the use of machine tools such as CNC milling machines, CNC lathes, milling machines, tapping drilling machines, and similar equipment. This category exclusively employs straight taps or spiral taps. Straight taps are utilized for machining through holes, while spiral taps are employed for machining blind holes.

On the other hand, hand taps are manually operated and often paired with a tap wrench. Formerly, hand taps were available in three variations (coarse, semi-finished, and fine), but advancements in materials and geometric designs have led to the necessity for only one type of hand tap. The advantages of using a single hand tap include speed and compatibility with running machines when required, particularly for managing cut material chips. Hand tapping generates fine chips, making it suitable for tapping blind or through holes.

1.2 Based on Thread Characteristics

Taps are commonly classified based on the thread pitch into standard pitch taps and fine pitch taps, also known as fine thread taps.

Standard pitch taps, such as M10x1.5 and M8x1.25, are widely used.

Fine pitch taps, like M10x1.25 and M8x1, have a smaller pitch compared to the standard pitch taps.

Both types of taps find extensive application in threading gas and water lines, as well as in the food industry to ensure secure threaded joints and prevent leaks.

1.3 Based on Thread Direction

Taps can also be categorized based on thread direction into right-thread taps and left-thread taps. The right-threaded tap features a clockwise thread and is commonly utilized. Conversely, the left-threaded tap has a counter-clockwise thread and is often employed in copper transfer thread joints, such as rotor threads or glass joints in motorcycles.

1.4 Based on Material Processing

Depending on the type of processing material, taps are manufactured from distinct billet types such as scrap billet or wire billet, each possessing varying hardness characteristics.

Common classifications encompass regular steel taps, hardened steel taps, stainless steel taps, aluminum + copper taps, and cast iron taps.

When engaging in large-scale and batch machining, selecting the appropriate tap suited for the material is crucial to ensure tap longevity, product quality, and machining productivity.

1.5 Based on Thread Standards

Different standards for thread usage are applied within each region or country.

While commonly referred to as MET and INCH tap taps, the reality is more nuanced. The MET tap tap is prevalent in Asia and is a popular tap type in Vietnam, typically denoted by the letter M. Conversely, the INCH tap tap is utilized in Europe, America, and Australia. However, each region and country has specific standards pertaining to tap and thread selection.

1.6 Based on Chip Classification

Taps can be categorized into cutting taps and forming taps based on the processing method. A cutting tap is employed to create chips, whereas a forming tap doesn't produce chips but instead compresses them.

The current market offers a diverse range of taps with varying sizes, applications, and specifications to cater to the diverse processing requirements of consumers.
