Applications

These boring bars are developed for versatile internal machining in various metalworking tasks. Featuring a 107.5-degree approach angle and utilizing standard 55-degree rhombic inserts, the tools are highly suited for longitudinal turning, internal profiling, and enlarging existing bores. The staggered minimum bore diameters accommodate a wide range of workpiece dimensions. This flexibility renders the set a valuable asset for general engineering and precision manufacturing shops, where varying contour requirements are common.

Special features

The solid steel body of the tool holders absorbs vibrations during the cutting process, thereby supporting a consistent surface finish on the internal contours of the workpiece. The streamlined screw clamping mechanism securely locks the insert in place while ensuring unimpeded chip evacuation, as there is no top clamp to obstruct the flow. By relying on widely standardized insert geometries, this set promotes cost-effective inventory management and efficient tool changes on the shop floor.
