Mechanical tool holders are essential components in machining operations that hold cutting tools in place. They come in different shapes and sizes, each designed for specific applications. In this blog post, we will discuss mechanical tool holders, their usage, and their application.
Mechanical tool holders are devices that secure cutting tools in place during machining operations. They are designed to prevent the cutting tool from slipping or moving during the operation, which can result in poor-quality parts, damaged tools, and even injury.
Mechanical tool holders are used in a variety of machining operations, including milling, drilling, turning, and boring. They are available in different types, including collets, end mill holders, shell mill holders, and tapping holders.
Drill Chucks
Drill chucks are used to hold drill bits in place during drilling operations. They are available in different sizes and can hold drill bits with diameters ranging from 1mm to 13mm
Collets
Collets are the most common type of machine tool holder. They are used to hold drills, taps, and end mills in place during machining operations. Collets are designed to grip the tool tightly, preventing it from slipping or moving during the operation.
End Mill Holders
End mill holders are used to hold end mills in place during milling operations. They are designed to provide maximum rigidity and accuracy, ensuring that the end mill stays in place during the operation.
Shell Mill Holders
Shell mill holders are used to hold shell mills in place during milling operations. They are designed to provide maximum rigidity and accuracy, ensuring that the shell mill stays in place during the operation.
Tapping Holders
Tapping holders are used to hold taps in place during tapping operations. They are designed to provide maximum rigidity and accuracy, ensuring that the tap stays in place during the operation.
CNC lathes are made up of many elements to ensure they operate correctly and deliver the desired geometry. Tool holders are an essential part of the process and a deep understanding of their technical specifications is fundamental for choosing the right one. The following article provides an in-depth discussion of what tool holders are, the different types available and how to choose the most appropriate one for your production process.
The tool holder is an attachment system for the cutting tools used when machining on a lathe, or any other machine tool. That is, tool holders are used to attach a cutting tool during the machining process. They also facilitate torque transfer from the lathe spindle to the cutting tool.
They are mainly used in a wide variety of CNC lathe applications. Different tool holders are required for different types of machining or cuts. It is essential they ensure high geometric accuracy to guarantee the quality of the finished parts. Maintenance is also crucial, because a tool holder with signs of excessive use can lead to costs due to defective parts. For that reason it is advisable to conduct thorough routine checks and ask your supplier for the estimated change date.
For example, a common bad practice which should be avoided is to secure the cutting tool into the tool holder while it is assembled in the turret. This practice creates deformations in the track the tool holder flange travels along when the turret turns.

Related articles:There are different types of tool holders for different applications. There are two main groups: driven tool holders and static (non-driven) tool holders. Driven tool holders:
There are also tool holders with both characteristics, that is, they are both axial and radial. With these tool holders, the angle of the tool can be adjusted +- 90º, so they can fulfil both functions. These tool holders are called orientable live toolholders, and they offer many advantages for machining.
On the other hand, static tool holders include:
In this case as well, there are multifunctional tool holders which offer many advantages and high flexibility for machining. There are tool holders which can be used for internal and external machining. Work is done simultaneously with two tools mounted in the same turret. While one tool works on the left spindle centre line, the second works on the right spindle centre line at the same time. These tool holders, known as double tool holders, are of great interest for anyone wanting to take their machining to the next level.
Finally, another of the interesting technical characteristics of some tool holders is that the cutting fluid can be applied on the outside (external) and inside of the tool (internal) There is a valve to select how the cutting fluid flows onto the cutting tool.
The correct choice of tool holder is essential for optimising machine performance and ensuring precision machining. Many characteristics influence the choice of tool holders best suited to your production needs. These characteristics include:
These are some of the characteristics to be taken into account when choosing a tool holder. In any case, it is important to ask a trusted supplier to advise you on the purchase of your tool holders to ensure the correct fit with both the type of tool and the way it attaches to the turret.
