Threadinsert

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.

Affected Organ Systems: Cancer, Dermal (Skin), Developmental (effects while organs are developing), Immunological (Immune System), Respiratory (From the Nose to the Lungs)

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.

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:

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.

In conclusion, we are committed to ensuring precision in your thread turning tasks. Should you require any assistance in using our chart, selecting the appropriate toolholder and insert, or other inquiries, our technical support team is ready to help. Contact us at info@smicut.se.

ToxGuidepdf icon[99 KB] - Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.

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

Minimal Risk Levels (MRL) - The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.

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.

Toxicological Profile - Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.

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.

Summary: Nickel is a very abundant natural element. Pure nickel is a hard, silvery-white metal. Nickel can be combined with other metals, such as iron, copper, chromium, and zinc, to form alloys. These alloys are used to make coins, jewelry, and items such as valves and heat exchangers. Most nickel is used to make stainless steel. Nickel can combine with other elements such as chlorine, sulfur, and oxygen to form nickel compounds. Many nickel compounds dissolve fairly easy in water and have a green color. Nickel compounds are used for nickel plating, to color ceramics, to make some batteries, and as substances known as catalysts that increase the rate of chemical reactions. Nickel is found in all soil and is emitted from volcanoes. Nickel is also found in meteorites and on the ocean floor. Nickel and its compounds have no characteristic odor or taste.
