Any machinist worth their salt will ensure they have a tool for threading holes securely tucked away in their toolkit. It’s important to select the appropriate tool according to the size and shape of the hole to be threaded, as tools come in a massive variety of constructs and sizes.
For threading holes, a tap is the usual choice. Ranging from tiny to grandiose, the perfect tap size and style corresponds with the size and kind of hole that needs to be threaded. Both manual and powered options are available – working together to create internal threads.
When threading holes that must have an outwardly facing opening, a die is the tool of choice. Hand-operated and powered varieties of dies exist to provide the necessary precision, both featuring diverse sizes and styles for all manner of tasks. Appropriate selection is dependent upon the size and configuration of the hole being threaded.
Knowing the proper size and type of tap or die to use is essential when carrying out any task. Neglecting to select the right one can result in serious harm to both the material and the tool, thereby disrupting your work.
Keeping the size of the hole to be threaded in mind is the primary factor when deciding which tap or die is most appropriate. With a myriad of sizes to choose from, from minuscule to immense, selecting the best tool for the task is effortless. The size of the target hole is directly linked to choosing the right size of tap or die.
When threading a hole, the type of tap or die used depends on the style of thread. Options include coarse and fine metric threads, as well as National PipeThread (NPT) and National Fine Thread (NF). It’s important to check the measurements of each thread type to determine which tap or die best suits your needs.
When deciding on the material of your project, you need to think about which type of tap and die is best. For softer material such as aluminum, brass, or plastic, you should opt for a tap and die set created to work with soft materials. For materials like steel and stainless steel that are more resistant, choose a tap and die tool designed for hard materials.
Finding the most suitable tap or die for a task requires precision and care. After all, opting for an incorrect size or style can result in damage to both the workpiece and the tool.
