Tungaloy JBRR07290050-D068 SH730 Solid Boring Bars

Description:

The Tungaloy JBRR07290050-D068 SH730 solid boring bar is used in CNC internal boring, grooving, and profiling systems for precision metal machining. Commonly installed in CNC lathes, Swiss-type lathes, turning centers, and high-precision machining equipment for small-diameter internal machining operations. Maintenance teams, machinists, and manufacturing engineers use this tool for replacement, production machining, and precision internal boring and profiling applications.

Applications:

The Tungaloy JBRR07290050-D068 SH730 solid boring bar is designed for precision internal grooving and full-radius profiling in small bores where rigidity and dimensional accuracy are critical. Its solid carbide construction minimizes vibration while the SH730 PVD-coated grade provides excellent wear resistance and edge stability. The tool is widely used for machining hydraulic components, medical devices, aerospace parts, precision valves, automotive components, and other high-accuracy internal features requiring superior surface finishes.
