Kyocera TSJ00246 Turning Insert Ccmt 80 Diamond Cermet

Product Description

The KYOCERA TSJ00246 is a CCMT-style cermet turning insert designed for precision metal cutting in CNC and manual turning applications. Manufactured to ANSI and ISO standards, this insert features an 80-degree diamond shape (Insert Shape Code C), a positive rake angle of 15 degrees, and a honed cutting edge for consistent, repeatable performance on steel workpieces. The TN60 cermet grade with TiCN and NbC coating process delivers wear resistance suited to finish and semi-finish turning. With two cutting edges per insert and screw-type holding, it is a practical choice for high-volume production environments where dimensional consistency is critical.

This insert is intended for use on steel workpieces classified under material grade P01, P10, and P20, making it well suited to finish turning and light semi-finish passes on carbon and alloy steels. Applicable operations include boring, external turning, chamfering, facing, and internal facing. The HQ chip breaker geometry promotes controlled chip evacuation during these operations. It is a multi-use insert appropriate for both live-tool and conventional CNC lathe setups where positive-rake tooling is specified.

Key Features

• CCMT insert style with 80-degree diamond shape for strong cutting edge and versatile entry angles
• TN60 cermet grade with TiCN and NbC for wear resistance on steel (P01, P10, P20 material grades)
• Positive rake angle of 15 degrees with honed cutting edge reduces cutting forces on finish passes
• HQ chip breaker geometry supports controlled chip flow in boring, turning, chamfering, facing, and internal facing
• Two cutting edges per insert extend usable tool life per unit
• Screw-type insert holding method for secure, repeatable seating in compatible toolholders
• Conforms to ANSI and ISO standards; ISO code CCMT09T302HQ, Industry Standard Number CCMT32505HQTN60

Compatibility

Designed for use in CCMT-style toolholders conforming to ANSI and ISO insert seating standards. Suitable for CNC and manual lathes performing boring, external turning, chamfering, facing, and internal facing on steel workpieces. Verify toolholder pocket geometry and clamping screw compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque-rated clamping screw and insert key specified by the toolholder manufacturer — do not overtighten or substitute fasteners. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper contact and runout control.
