Mark all as readModular Boring Bars with Serrated Interface
These boring bars utilize a new portfolio of bolt-on heads that connect to the bar by a serrated design.
- Short design bolt-on heads result in low weight, providing high stability and consistent repeatability.
- Serrated design interface provides higher connection strengths, enabling an increased accuracy of insert positioning.
- Vibration-Free boring bars provide stability and rigidity when boring at extended overhangs up to 10xD.
- Vibration-Free boring bars are a plug-and-play solution designed to work out of the box with no manual adjusting required or possible. The internal dampening package is designed to provide process stability by increasing the stiffness of the bar and dampening out chatter.

Modular Steel Boring Bar
- Modular steel boring bar with through coolant.
- Boring with overhangs up to 4xD.
Vibration Free Boring Bar
- Vibration free boring bars with internal dampening package.
- Ensures vibration and chatter-free machining, allowing high metal removal rates and large depths-of-cut, resulting in high surface quality and increased productivity.
- Boring with overhangs up to 10xD.
