Sumitomo 16JRCWB Pcbn Turning Insert 3/16 in Triangle

Product Description

The SUMITOMO 16JRCWB is a Polycrystalline Cubic Boron Nitride (PCBN) turning insert designed for single-point metal cutting operations on steel workpieces. Manufactured to the BN2000 grade, this uncoated insert features a triangular shape with a 60-degree included angle, a 3/16-inch inscribed circle, and a 1/64-inch corner radius. The positive rake geometry and NU-TPGD style designation make it suited for precision turning applications where tight tolerances and consistent edge performance are required. Machining professionals and CNC operators install this insert into compatible toolholders for finishing and light roughing passes on hardened and difficult-to-machine steel materials.

The 16JRCWB is intended for use in turning centers and CNC lathes where steel is the primary workpiece material. Its PCBN construction performs well on hardened steels and similar ferrous materials where conventional carbide inserts wear prematurely. The screw-holding method provides secure clamping in standard NU-TPGD style toolholders. With a maximum depth of cut of 0.0150 inches, this insert is optimized for light finishing cuts requiring precise dimensional control and smooth surface finishes. It conforms to ANSI and ISO 13399 standards, with an ISO code of NU-TPGW080204.
