Threading Holder

What Are Threading Holder?

Products like a smartphone, automobile, etc. are all an essential part of lives. They cannot be created without producing the parts that comprise them, which is done by using machine tools. During the process, cutting, grinding, and drill of metal material are undertaken.

Threading holders, also known as the threading tool holders or shortened as tool holders, are a machining component that is used to mounting the cutting tools in machine tool equipment to carry out the operations mentioned above. Threading tool holders can affect the accuracy of machine tools, hence the quality of product. So they are typically designed to offer the highest precision that even the slightest bit of error is not permitted.

Applications of Threading Holder

One thing we should all keep in mind is that there is no “one-size-fits-all” when it comes to tool holding. In other words, you will not find a threading tool holder that can be used across all applications.

To better illustrate, threading tool holders that are designed to perform high speed finish operation will normally be compromised in strength and rigidity. Also, a tool holder that is engineered for rough machining will typically lack the ability to allow machine tools to run smoothly at high speed in finishing operations.

Simply put, what type of threading tool holder you choose is very much relative to the quality of your work piece. For instance, you will need threading tool holders with superior strength and rigidity for tougher workpiece materials.

With the above said, you should always refrain from choosing an inappropriate tool holder that isn’t suitable for the job. This can result in dimensional inconsistency, scrapped parts accompanied by excessive wear on machine tool spindles, as well as decreased lifespan and increase in tool breakage. Therefore, to help you choose the right tool, we’ll address some of the selection factors in the subsequent section.

Budget Concerns for Threading Tool Holders

Generally speaking, you can get away with standard priced threading tool holders for low intensity jobs. However, if you are undertaking operations that require repeatable precision, you’ll need to invest in a specialty holder that tailors to the intended applications even if it means to incur more upfront cost. This will ensure that satisfactory result is produced while protecting you against unanticipated losses (e.g., repair, replacement, etc.).

For keeping the expenses down, many shop owners opt for longer tool holders. Although valid, sometimes it is better to use the shortest tool holders possible for maximum strength, while keeping surface-degrading vibration to the minimum. Whatever your cost-saving strategy is, choosing the right tool is always more important because tool holders are only made up of less than 2 percent of total production costs. Even with limited budget, your cost-saving strategy should not revolve around the threading tool holders because the savings are relatively negligible while broken tool or scrapped work pieces can have way more adverse financial impact. 

Workpiece Factor for Threading Tool Holder Selection

As we’ve already touched base above, the machinability of the workpiece material will hugely affect how you go about choosing your threading tool holders. The idea is easily reflected on the distinct dimensions of the tool holder for various applications. Choosing the right tool relative to your workpiece can ensure that the process is as simple as it can be, thereby minimizing the possibility of error. That said, yet, a machine tool’s strength, spindle power and the ability to produce tight tolerance are what truly decide the feasibility of operations regardless of the tool holding method. 

Machine Tool Factor for Threading Tool Holder Selection

Following the above, the machine tool’s basic qualities are also associated with holder selection. A fast machine with linear guide way is often coupled with a tool holder engineered for high speed application, whereas a multi-tasking oriented machine will be able to take advantage of tool holders with both milling and turning capability.

Your machining strategy always plays a role in tool holder selection. For example, tool holders may be chosen based on how your production is deployed. It could be high speed cutting (HSC) operation involving lighter and shallower cuts, or it could be high performance cutting (HPC) where maximizing metal removal rates are emphasized, both of which will guide you to selecting a distinctly different threading tool holder.


As we keep emphasizing, a thread tool holder is one of those with its niche, meaning the type and model are largely depended on the intended operations. For example, simple endmill holders for welded shank tools are rigid, easy to use, can transmit elevated torque and provide a strong anti-pull out action for secure and strong clamping. They are well adapted but lack precise concentricity for extreme roughing.

The bottom line is – usability over affordability – as the upfront cost is so insignificant that it should not even be one of the major elements in your cost-saving scheme. You should be more concerned about the unexpected and potentially significant expenses that may incur later on from poor selection.
