Firstly, in the SmiCut catalogue, we specify the approximate minimum bore size for each toolholder. This is the smallest diameter that the tool can enter. However, it’s important to note that the actual size can vary depending on the insert you use.

To assist you further, we’ve developed a chart that helps you determine the exact minimum bore diameter for our thread turning toolholders, based on the insert used.

Selecting the right tools for threading operations is crucial for precision and efficiency. To ensure you choose the appropriate size of the toolholder and insert, follow these steps:

When producing internal threads with a thread turning operation, one important factor is the minimum bore diameter. This dimension plays a key role in selecting the right tools for a specific thread.

By knowing the correct minimum bore size measurement, you can choose the best tools for the threads you need to produce.

For instance, if you’re using an SIR_0020_P16 toolholder with an 16IR_1.25ISO_FC insert, and the X-measurement for the 16IR_1.25ISO_FC insert is 0,8 mm (as found in our Catalogue or Online Store), the minimum bore diameter for the SIR_0020_P16 toolholder would be 22,9 mm as you can see in the PDF chart.

The X- measurement represents the distance from the cutting edge to the size of the insert (L). This measurement varies with the pitch of the insert.
