If the value falls within the blue area (1.5° standard), the anvil that comes with the holder is the most suitable. If it falls outside the blue area, we recommend switching to an appropriate anvil.

Go to our Helix Angle Calculator with Anvil Selector Tool to calculate the exact helix angle and get recommendations for a suitable anvil based on the type of threading insert you are using.

This industry comprises establishments primarily engaged in fabricating plate work and structural products by cutting, punching, bending, shaping and welding purchased steel plate.

To achieve optimal cutting properties, the threading insert must be adjusted in the holder to match the thread’s helix angle. This is usually accomplished using anvils (also known as insert shims) that adjust the insert’s angle. Ensuring the correct setup guarantees that the tool operates with maximum efficiency, minimizes the risk of errors, and extends the tool’s lifespan.

The diagram illustrates how FourCut uses the same holder for many different diameters and pitches. This threading tool, which doesn’t require anvils, is a smart and flexible choice because almost all threads can be manufactured with the standard holder.

A solid understanding of the helix angle of a thread is crucial for successful thread turning. The helix angle describes how much the sides of the thread incline. A thread is not a straight groove but a spiral winding around a cylinder. If the angle of the threading insert in the holder is not correctly aligned with the thread’s helix angle, you risk excessive tool wear and defective threads.

For triangular inserts, it’s important that their angle matches the thread’s helix angle. If a lower or higher angle is needed, you can adjust by changing to a suitable anvil.

When using triangular inserts, it’s important that the holder’s setup matches the thread’s helix angle. The standard holder for triangular inserts has a preset angle of 1.5°. If you need to adapt the tool for a different helix angle, you can switch to a suitable anvil to match the thread’s helix angle and ensure optimal machining.

A major advantage of FourCut inserts is their extra flank clearance. This eliminates the need to precisely match the thread’s helix angle. The standard holder has a preset angle of 2°, allowing almost all threads to be made with the same holder. This offers enormous flexibility and enables the use of the same holder for different helix angles.

Select the right anvil based on the threading insert you’re using and the angle you need. In the table, you’ll find the part number to use when ordering. Negative angles on anvils are used when producing a right-hand thread with a left-hand tool or a left-hand thread with a right-hand tool.
