Kyocera TSJ00350 Turning Insert TN60 Cermet 5/16 in

Product Description

The KYOCERA TSJ00350 is a cermet turning insert designed for precision metal cutting in CNC turning and boring applications. It follows the CPMH insert style with an 80-degree diamond shape, providing a strong cutting geometry well-suited for finishing and semi-finishing passes on steel workpieces. The insert carries the TN60 manufacturer grade with a TiCN plus NbC coating classification, though it is applied as an uncoated cermet substrate. With a 5/16-inch inscribed circle, a 0.3125-inch insert length, and a 1/64-inch corner radius, this insert delivers tight tolerances under the M tolerance code and a positive rake geometry for reduced cutting forces.

This insert is intended for steel turning applications, particularly in the P01, P10, and P20 material grade ranges. It is suited for internal operations including boring and internal facing on CNC lathes and turning centers. The neutral hand orientation and screw-type holding method make it compatible with standard CPMH-style toolholders. Two cutting edges per insert provide cost-effective usage in production turning environments. Licensed machinists and CNC operators in job shops and manufacturing facilities are the primary users of this insert.

Key Features

• 80-degree diamond insert shape with positive rake for reduced cutting forces on steel
• TN60 cermet grade with TiCN plus NbC composition suited for P01 through P20 steel grades
• 1/64-inch corner radius with M tolerance code for consistent dimensional accuracy
• Neutral hand orientation compatible with standard CPMH screw-on toolholders
• Two cutting edges per insert for extended tooling value in production runs
• Meets ANSI and ISO standards with ISO code CPMH080204

Compatibility

Designed as an OEM-style replacement for CPMH-style screw-on turning insert seats. Compatible with toolholders designed for insert size code 25151 and the CPMH insert style per ANSI and ISO standards. Suitable for boring and internal facing applications on steel workpieces in the P material group.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully against the pocket locating surfaces before tightening the clamp screw to avoid insert rocking or chipping. Follow the toolholder manufacturer torque guidelines for the clamp screw and inspect the insert seat for chips or debris before each insert change.
