Applications

The E-FIT SDQCR/L boring bar shows its strengths when profiling complex internal contours. Thanks to the 107.5° angle and the compatible rhombic inserts, it is highly suitable for machining difficult-to-reach areas in industrial manufacturing environments.

Special features

A key advantage of this tool holder is its integration into the modular E-FIT boring bar system. This design allows for quick changes of the cutting heads, which minimizes setup times and increases cost-efficiency. The direct screw clamping of the insert also guarantees backlash-free positioning for consistently high accuracy under varying operational demands.
