Kyocera TSJ03110 Turning Insert VBMT222HQ TN60 Cermet

Product Description

The KYOCERA TSJ03110 is a cermet turning insert in the VBMT style, designed for precision metal cutting on CNC lathes and turning centers. It carries a 35-degree diamond (V) shape with a neutral hand orientation and a positive rake angle of 15 degrees. The TN60 grade cermet substrate is finished with a TiCN and NbC coating applied via an uncoated classification process, making it well suited for fine finishing and semi-finishing passes on steel and stainless steel. With 2 cutting edges per insert and an HQ chip breaker geometry, it delivers controlled chip formation and consistent surface finish across a range of turning operations.

This insert is intended for external turning, facing, copying, profiling, back boring, internal facing, and undercutting applications. Its primary workpiece material designation is steel (ISO code P), with stainless steel (ISO code M) as a secondary material. Material grades P01, P10, and P20 apply, making it suitable for light to medium-duty cuts where tight tolerances and fine finishes are required. It follows both ANSI and ISO standards, with the ISO code VBMT110308HQ and industry standard number VBMT222HQTN60.

Key Features

• 35-degree diamond insert shape (V code) with positive rake for reduced cutting forces on steel
• HQ chip breaker geometry supports controlled chip evacuation during finishing and semi-finishing
• TiCN and NbC coating on TN60 cermet substrate for wear resistance and thermal stability
• Neutral hand orientation with honed cutting edge for consistent edge life
• Screw-clamping insert holding method compatible with standard VBMT toolholders
• Multi-use design supports back boring, copying, external turning, facing, internal facing, profiling, and undercutting

Compatibility

Designed for use in standard VBMT-style screw-clamp toolholders conforming to ANSI and ISO mounting specifications for diamond 35-degree turning inserts.

Installation Notes

Installation is performed by machining professionals on CNC or manual turning equipment. Before seating the insert, ensure the toolholder pocket and clamp screw are clean and free of chips or debris. Torque the clamp screw according to the toolholder manufacturer specifications. Index or replace the insert when cutting edge wear affects surface finish or dimensional accuracy.
