Precaution
![](https://www.sumitool.com/en/products/cutting-tools/assets/mt-images/attension_x-bar.gif)
Clamping on labeled portion may prevent the tool from working correctly (due to the built-in anti-vibration mechanism). Therefore, minimum tool overhang should be 3.5D.

1. Achieves 6D deep hole boring for ø32mm or more.
2. Negative type insert reduces the per corner cost.
3. Coupled with a wide selection of chipbreakers to cover a wide range of applications from roughing to finishing.
