S16R-SDJCR11 Boring Bar

The S16R-SDJCR11 Boring Bar is a high-quality internal toolholder engineered for DCMT 11 positive inserts. With its 16 mm round shank, the S16R-SDJCR11 Boring Bar provides rigidity and precise performance in boring, internal turning, and profiling operations. Featuring a secure screw-clamping system, the S16R-SDJCR11 Boring Bar ensures stable insert positioning, reduced vibration, and extended tool life when machining steels, stainless steels, and non-ferrous alloys.

Its 93° approach angle makes this boring bar versatile for a variety of internal operations, especially in tight bores. The positive rake geometry of DCMT inserts minimizes cutting forces, improves chip evacuation, and delivers high-quality surface finishes. This toolholder is ideally suited for finishing and semi-finishing, where precision and consistency are critical.

The compact 16 mm shank allows the S16R-SDJCR11 to enter smaller bores while still providing strong performance. This makes it a dependable choice in automotive, aerospace, and precision machining industries where internal features must meet strict tolerances.
