Kyocera TSJ00500 Turning Insert Cermet 55 Diamond TN60

Product Description

The KYOCERA TSJ00500 is a cermet turning insert engineered for precision metal removal on steel workpieces. Manufactured to the DCGT insert style with a 55-degree diamond shape, this insert carries the TN60 manufacturer grade and features a TiCN and NbC coating applied to a cermet substrate. It is designed for positive rake cutting with a neutral hand orientation. The inscribed circle measures 0.25 inches, insert length is 0.614 inches, and the corner radius is 0.004 inches. With two cutting edges and a screw-style holding method, it fits toolholders configured for DCGT-style inserts in CNC and manual turning applications.

The TSJ00500 is suited for external turning, copying, back boring, and sub-spindle operations on steel. Primary workpiece material is steel, with material grades rated P01, P10, and P20, making it appropriate for finishing to semi-finishing passes on low-to-medium carbon and alloy steels. This insert is used in CNC lathe and turning center setups where tight tolerances and consistent surface finish are required. Machinists and CNC operators working in production or job-shop environments will find it compatible with standard DCGT toolholder pockets.

Key Features

• Cermet substrate with TiCN and NbC coating for wear resistance on steel
• 55-degree diamond insert shape (DCGT style) with positive rake geometry
• Neutral hand orientation supports versatile toolholder mounting
• Two usable cutting edges per insert
• Screw-style insert holding for secure clamping in standard pockets
• Rated for back boring, copying, external turning, and sub-spindle use

Compatibility

Designed as an OEM-style replacement and standard-production insert for DCGT-style toolholders conforming to ANSI and ISO standards. ISO code DCGT070201 and industry standard number DCGT21502TN60 apply. Compatible toolholders must accept a screw-held DCGT insert with a 0.1102-inch hole diameter and a 0.25-inch inscribed circle.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret or toolholder is secured before seating or indexing the insert. Use the correct torque screwdriver for the insert clamping screw to avoid cracking the cermet substrate — do not over-torque. Verify toolholder pocket cleanliness and seating surface condition before each insert change to maintain dimensional accuracy.
