Kyocera TSJ00248 Turning Insert Ccmt TN60 Cermet 3/8in Ic

Product Description

The KYOCERA TSJ00248 is a CCMT-style cermet turning insert designed for precision material removal in CNC and manual turning applications. Carrying the TN60 manufacturer grade, this insert features an 80-degree diamond shape with a positive rake angle of 15 degrees and a honed cutting edge for clean, consistent performance on steel workpieces. The TiCN plus NbC coating classification is listed as uncoated process, and the cermet substrate provides a balance of hardness and thermal resistance suited to finish and semi-finish turning operations. Holding is accomplished via screw clamp, and the insert is neutral-handed for flexible toolholder compatibility. It is sold individually with a minimum order quantity of 10 units.

This insert is intended for use on steel workpieces in material grade ranges P01, P10, and P20. Typical applications include external turning, boring, chamfering, facing, and internal facing. The HQ chip breaker geometry is optimized for finish-to-semi-finish cuts on steel, making this insert a practical choice for production turning cells and job-shop environments where consistent surface finish and edge life are priorities. Licensed machinists and CNC operators working on ferrous materials in both light and medium cutting conditions will find this insert well suited to their tooling programs.

Key Features

• CCMT insert style with 80-degree diamond shape and neutral hand for wide toolholder compatibility
• TN60 cermet grade with HQ chip breaker geometry optimized for steel finish and semi-finish turning
• Positive rake angle (15 degrees) with honed cutting edge for reduced cutting forces and cleaner chip formation
• Two cutting edges per insert for extended tooling value
• Screw-clamp holding method ensures secure seating under interrupted and continuous cuts
• Multi-use geometry supports boring, external turning, chamfering, facing, and internal facing in a single insert

Compatibility

Designed for use in CCMT-compatible screw-clamp toolholders. ISO code CCMT09T304HQ and industry standard number CCMT3251HQTN60 can be used to cross-reference compatible toolholder systems. Suitable for P-class (steel) workpiece materials per ISO material grade designations P01, P10, and P20.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician following the toolholder manufacturer's torque and seating guidelines for CCMT screw-clamp inserts. Ensure the machine spindle is fully stopped and locked out before indexing or replacing the insert. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Do not exceed the maximum depth of cut of 0.125 inches to avoid insert fracture or premature edge failure.
