Tungaloy Co., Ltd. JBGR07210100-D068 SH730 Boring Bar

Description:

The Tungaloy JBGR07210100-D068 SH730 boring bar is used in CNC internal grooving and precision metal cutting systems. Commonly installed in CNC lathes, Swiss-type lathes, turning centers, and precision machining equipment for small-diameter internal grooving operations. Maintenance teams, machinists, and manufacturing engineers use this tool for replacement, production machining, and precision internal grooving applications.

Applications:

The Tungaloy JBGR07210100-D068 SH730 boring bar is designed for precision internal grooving and boring 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 stable cutting performance. It is widely used for machining hydraulic components, valve bodies, aerospace parts, medical devices, and precision mechanical components requiring high-quality internal grooves and superior surface finishes.
