Kyocera TKT03955 Turning Insert VPGT151505CK PR930 Carbide

Product Description

The KYOCERA TKT03955 is a VPGT-style indexable turning insert in grade PR930, designed for precision metal cutting on CNC lathes and turning centers. The insert features a 35-degree diamond shape (V), a 3/16 inch inscribed circle, and a 0.008 inch corner radius with a honed cutting edge. The TiCN coating is applied via PVD process over a super micrograin solid carbide substrate, delivering sharp, consistent edges suited for finishing and semi-finishing passes. With a positive rake angle of 20 degrees and a neutral hand orientation, it is well-suited for external turning, facing, profiling, and internal facing operations. Licensed machinists and CNC operators are the primary installers.

This insert is rated primarily for steel (ISO material code P) and secondarily for stainless steel (ISO material code M). Typical applications include external turning, back boring, copying, facing, internal facing, profiling, and undercutting operations. The CK chip breaker geometry is optimized for light-to-moderate depth cuts, with a maximum depth of cut of 0.2101 inches. It fits screw-on insert holders designed for VPGT-style inserts with a 0.0906 inch hole diameter. This insert ships in individual unit packaging with a minimum order quantity of 10.

Installation Notes

Installation is performed by licensed machinists or CNC tool setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the screw-on insert. Inspect the insert pocket seat for chips or debris before seating the insert to ensure proper contact and repeatability.
