Whistle-Notch

What is Whistle Notch?

Whistle Notch is a special mounting method that provides a reliable and supportive way to attach tools to holders. This fastening method is especially used in carbide drill bits where high precision and reliability are required. Tools equipped with Whistle Notch are attached to special Whistle Notch holders that are designed to support and stabilize the tool during use.

Features of Whistle Notch Mounting

The unique feature of the Whistle Notch mounting system is its transverse securing surface, which is slightly slanted. This slant allows the fastening force to be directed along the tool axis toward the rear of the tool, preventing the tool from slipping out of the holder. This improves the strength and stability of the grip, reduces the risk of tool pull-out, and enhances machining accuracy.

Whistle Notch vs. Weldon

While the Whistle Notch securing surface is similar to the Weldon system, there are significant differences between them. In the Weldon system, the securing force is applied directly to the transverse surface, which can increase the risk of the tool being pushed out. In the Whistle Notch system, the transverse surface is slanted, directing the securing force along the tool axis toward the rear of the tool. This reduces the risk of pull-out and provides a more reliable grip.

Summary

Whistle Notch is an innovative and reliable fastening method that offers an excellent way to secure carbide drill bits to holders. Its unique slanted securing surface directs the clamping force along the tool axis, reducing the risk of pull-out and improving both machining accuracy and safety. This makes the Whistle Notch system an outstanding choice for machine shops and manufacturing plants where high precision and reliability are essential.
