Types of Metal Threading Tools: What to choose? 

You have to choose metal threading tools based on the type of operation needed.

Types of Threading toolsModeMachineryApplication
Thread rollingManualManual Fine and smooth threads

Tapping and threadingManual and machineDrilling, tapping machinesThreading blind, small holes
Single-point thread cuttingMachineLathe machineBatch production or unique threads like V shape threads
Types of threading tools and their features

Thread Rolling Tools

You can produce fine and smooth threads using thread-rolling tools.

The process of metal forming allows the formation of thread without wasting a lot of material in the form of chips.

It is ideal when working on thin spokes, small-length threads, or expensive material.

Thread Milling Tools

Thread milling tools are much more versatile as they offer a wide range of thread dimensions, higher tolerance, and accuracy.

You can equip a milling machine with a thread milling tool to machine threads on holes of large diameter.

A change in the cutter's rotation direction helps achieve right-hand or left-hand threads.

The thread milling process can quickly achieve threads with a pitch greater than 15". Lead screws are often produced using these tools.

Tapping and Threading Tools

Tapping and threading involve the use of taps and die to form thread. It includes both metal cutting and metal forming processes.

You can perform such jobs using a drilling or tapping machine. It facilitates threading small blinds or through holes.

Single-Point Thread cutting Tools

Single point cutting tool usually used in a lathe machine offers threading operation with minimal material removal.

These tools are suitable for batch production and developing unique threads like V-threads.

Things to Consider When Selecting Metal Threading Tools

There are several factors to consider when choosing a tool for metal threading:

Size and shape of the workpiece

The size and shape of the workpiece will influence the tool that can be used.

For example, a large threading tap may be required to thread a large hole, while a small-diameter tapping tool may be sufficient for small holes.

Also, if you want to thread oddly shaped workpieces, you'll have to work with a thread milling tool.

But when working on symmetrical parts like a pipe or cylinder, you can thread with a single-point thread milling tool.

What metal are you planning to work with?

Before choosing a threading tool, you must consider the type of metal you are working with.

For example, taps and dies are typically used for cutting threads in soft metals such as aluminum or brass.

In comparison, tools like thread mills are better suited for threading more complex materials such as stainless steel, titanium, etc.

Internal or External Threads?

Threading tools are available in different configurations based on where on the workpiece you want to make the threads.

For example, taps are an excellent choice to create internal threads (threads on the inside of a hole), while dies are best at creating external threads (threads on the outside of a rod).

Thread Pitch

Nomenclature of a Thread
Nomenclature of a Thread

The thread pitch is the distance between threads. Your required thread type must match the tool used.

For example, a tool with a small cutter will create threads with a fine pitch (small distance between threads), while a tool with a large cutter will create coarse threads (more considerable distance between threads).

Thread Fit (Tolerance)

The thread fit is the tolerance between the threads of different parts.

A loose thread fit will only be suitable for low-stress applications, while a tight thread fit allows it to be used on high-stress applications.

Frequently Asked Questions

Which tool is suitable for threading hard materials?

Thread milling tools are an ideal choice for threading hard materials. Materials of hardness up to 62 HRc can be threaded using these tools. Cutters made of carbide facilitate a large rate of material removal.

Can I cut a square thread using a single-point cutting tool?

Yes, you can cut a square thread using a single-point cutting tool. Choosing the right pitch and cut depth will help achieve the right thread size. Setting the compound rest at 0 degrees and giving light cuts will help get a good thread.

What is the difference between a tap and a die?

Tapping tools and forming dies are two basic tools used in producing threads in a metal workpiece. A tapping tool help in cutting internal threads, whereas a forming die helps form an external thread on metal shafts.
